IETIC members are continuing to focus their efforts on seed supply issues. Efforts to establish two new seed orchards are underway. These new orchards will be "shared" by IETIC members interested in the seed. Both orchards are being established using the best genetic material available. Efforts are continuing to broaden our understanding and use of techniques designed to increase seed crops in seed orchards. These techniques include flower induction to increase crops and cone and seed insect monitoring and control to protect crops. IETIC is pursuing publishing of the western larch reproductive biology manual written for us by Dr. John Owens. This manual is designed for orchard managers and foresters interested in western larch seed crops.
Impacts
The IETIC continues to pursue selection, testing and breeding programs for 5 commercial tree species: western white pine, western larch, ponderosa pine, Douglas-fir, and lodgepole pine. The objective of these programs is to develop genetically improved materials that can be used to produced seed for reforestation and eocosystem restoration.

IETIC members have continued to focus on seed supply issues. Efforts are underway to study flower induction techniques in ponderosa pine and western larch seed orchards. In addition, we have been studying seed and cone insects with the aim of developing better monitoring and control measures. Several of our Idaho and Washington members have joined together to establish two new seed orchards, one for ponderosa pine and one for western larch. In addition, two of our Montana members have recently worked together to establish a new western larch seed orchard. We have contracted with Dr. John Owens to write a reproductive biology manual for western larch. This manual is designed for orchard managers and foresters interested in western larch seed crops.

During the year, the IETIC Steering Committee continued to make changes designed to shift some of our focus toward seed supply issues. Two important activities were 1) a review of management practices at the Missoula Ponderosa Pine Seed Orchard designed to increase seed yield and improve the consistency of crops produced at the orchard, and 2) a proposal to establish a new cost-share western larch seed orchard to provide improved seed for our Idaho and Washington members. In addition, members approved funding for five projects or studies that will provide important information to our seed orchard and breeding orchard managers. One of those projects is a contract to write a comprehensive reproductive biology manual for western larch, two are aimed at developing operational procedures to enhance flowering, and two are aimed at a better understanding of insects and insect control options in our orchards.

During the last year, the IETIC Steering Committee has made several changes aimed at positioning IETIC to better serve the needs of its members. The most significant change is the formation of two new working groups to address seed supply issues for Idaho/Washington and Montana members. IETIC members are continuing to discuss opportunities to use genetic material from the program to establish additional western larch, ponderosa pine and western white pine seed orchards. In addition, members have been discussing and evaluating the management of existing seed orchards in an effort to increase the supplies of genetically improved seed for reforestation. The Douglas-fir and lodgepole pine species groups are continuing to maintain long-term genetic tests. Some members have been collecting materials from these tests to establish their own seed orchards. In addition, IETIC members have been working closely with the USDA Forest Service to pursue advanced generation breeding
efforts in ponderosa pine, western larch, and western white pine.

During the last year, the IETIC examined member seedling needs and estimates of seedling production from existing seed orchards. The result showed a need for additional ponderosa pine and western larch seed orchards. These needs are currently being studied by the membership. Our oldest genetic tests were measured in 2001, providing us with 30- year growth data for ponderosa pine. These data are being used to select the best sources for new ponderosa pine seed orchards. The ponderosa pine species group continues to address management issues in the two cooperative ponderosa pine seed orchards. The white pine species group continues to manage the R.T. Bingham seed orchard for seed production. In addition, the group is grafting additional sources to expand the seed orchard. The new orchard will be blocked by blister rust resistance type. This group has also been collecting materials for the white pine breeding project. The western larch species group is continuing to
collect scion for second generation breeding efforts. Several larch genetic tests were measured in 2001. The Douglas-fir and lodgepole pine species groups are continuing to maintain their genetic tests. Some of our members have been collecting materials from these tests to establish their own seed orchards.

Some important staffing changes were recently made in the IETIC. Lauren Fins, resigned her position as Director and has become a quarter-time Scientific Advisor for the Cooperative. Long-time Assistant Director, Marc Rust, was selected to become the new Director. Joanna Mignano was hired to fill a one-half time Data Manager position and a three-eighth time Secretary position. In early 2000, the IETIC completed a new strategic plan. The plan identifies important objectives for the Cooperative and will be used to set priorities for the future. The White Pine Species Group of the IETIC continued to graft white pine selected for blister rust resistance for the establishment of a new seed orchard. The first grafts were planted in the new orchard in Spring 2000. The study of differences in needle surface morphology between samples from three nurseries and two resistance levels has been completed. Stomata on needles from susceptible families were generally wider and larger
compared to those from resistant families. In addition, statistically significant differences were found among samples from three nurseries for several needle characteristics. Further investigation is required to determine the importance of these findings to current white pine blister rust research efforts.

Progress 10/01/98 to 09/30/99
Outputs
We assisted the White Pine Species Group in developing a 5-year plan for expansion and installation of a second phase seed orchard that will increase the level of rust resistance from the predicted 66% to closer too 100%. Initial grafts were made in 1998 and additional grafts were made in spring 1999. Committee decided to remove parts of the existing orchard to make room for new grafts since the expansion land is not adequate to hold the four planned new orchard blocks. Scion was collected from the trees that will be removed and grafted onto rootstock to be planted in a gene archive. We have begun to analyze data from control-pollinated study of seed from the Moscow White Pine Seed Orchard. This is the second of two studies on rust resistance in orchard seed. Results from the first study show that both horizontal and vertical resistance types are present in the orchard and that the horizontal resistance appears to be more stable than the levels of ve3rtical resistance
from year to year. These results were published in the IETIC 1998 Annual Report. Results from the second study suggest little difference in resistance among progeny from trees initially identified as having different resistance mechanisms. Results from this study will be written in manuscript form for submission to a refereed journal. The Douglas-fir root-bark study was completed. Jenny Myszewski, the graduate student on the project has written two manuscripts for publication. Results which show that there are differences between Douglas-fir families in root-bark chemistry and that selection for these chemical differences is possible. Manuscripts are in revision and will be sent to journals in 2000. The study of differences in needle surface morphology between samples from three nurseries and two resistance levels is near completion. Results will be reported in the IETIC 1999 Annual Progress Report and will be submitted as three manuscripts to refereed journals.

We continue to assist the white pine species group in developing plans for a second phase seed orchard that will increase the level of rust resistance from the predicted 66% to closer to 100%. An agreement was reached between the University of Idaho and the White Pine Seed Orchard Group for allocation of additional acres to the north and south of and adjacent to the existing seed orchard. Scion was collected in February 1998 and grafted in the spring. However additional acres are needed to complete the orchard as currently designed. Deliberations continue. Seed from the Moscow White Pine Seed Orchard has been evaluated for types of blister rust resistance in the first of two studies. Results show that both horizontal and vertical resistance types are present in the orchard and that the horizontal resistance appears to be more stable than the levels of vertical resistance from year to year. The Douglas-fir root-bark study is almost complete. Jenny Myszewski, the
graduate student on the project is in the process of writing several manuscripts for publication of the results which show that there are differences between Douglas-fir families in root-bark chemistry and that selection for these chemical differences is possible.

Developed preliminary guidelines for blocking the two IETIC Ponderosa Pine Seed Orchards. Plans will be refined during the winter of 1995-96 and distributed to seed orchard managers to use in roguing the orchards. Result should be an upgrading of the seed with greater adaptability to local environments. Proposal for project to map white pine blister rust markers was funded. We have recruited a new graduate student to begin work on the project during 1996. Completed collections of rootbark samples from 20 families in each of two Douglas-fir progeny tests in the mid-elevation zone of Breeding Unit 12 (north Idaho/eastern Washington). Half of the samples were delivered to the analytical lab. Results due in early 1996. We have commitments from two cooperators to establish western larch seed orchards. We completed analyses and recommended individual tree selections for inclusion in the orchards.

Progress 01/01/89 to 12/30/89
Outputs
Emphasis in the project during the last year has been on developing a data base for decisions about cooperative seed orchards for IETIC members. The future of tree improvement lies in the ability of the member to capture genetic gains through planting genetically improved stock from seed orchards. Thus, the planning and establishment of seed orchards remains a critical factor in our future success. We continued to make strong contributions in technology transfer in the region. We analyzed data on 7-year height of western larch, 10-year-height of grand fir, 9-year height of lodgepole pine and 9 and 10 year height of western white pine. We completed and distributed reports of the larch and fir information in 1989, including genetic gains available through selection. In March 1989 we conducted a short course on Quantitative Forest Genetics in Corvallis. Sixty-six people attended the short course and the next outcome will be a book from the lectures by each
instructor. We have already secured a publisher and are about to sign a contract to finalize the agreement.

Progress 01/01/88 to 12/30/88
Outputs
Current major emphasis of the project is still data analysis and technology transfer. During 1988 we analyzed data from tests of two species - ponderosa pine and Douglas-fir, and provided information to cooperators about potential genetic gains from selecting the best individuals of these species to use in seed orchards. We also designed a breeding program/mating design for ponderosa pine in Montana breeding units. The information from both analyses was presented at the annual meeting of the Inland Empire Tree Improvement Cooperative, and results were compiled in a comprehensive report that was distributed to all members of the ponderosa pine species group. The Douglas-fir data will be further analyzed, and interpreted, and will be presented at a IUFRO conference in 1990. After those analyses, the results will be compiled and written up in a comprehensive report and distributed to all members of the Douglas-fir species group. The technical advisory committee of the
IETIC met six times in 1988 and developed a new fiveyear plan for the cooperative. In that plan, four important projects are described that will assist cooperators in tree improvement efforts in the near future, and which will require no additional funding. Five additional special projects were identified that will require further exploration and new support.

Outputs
Current emphasis in the project is on data analysis and technology transfer. Analysis and interpretation thereof will be used to guide members of the cooperative in their choices of genotypes to include in seed orchards and breeding orchards, and to design well-matched genotypes in breeding programs. New efforts include development of a project to determine appropriate coefficients for genetically improved trees in a growth and yield model; comparisons of early growth data with later growth data from nursery tests, and comparisons of nursery performance and field performance over time. An additional project emphasizes changes in growth patterns of western larch families and populations over time (six-year-old trees compared to two-year-old trees.) Also, a comparison of shoot growth patterns of lateral branches compared to terminal branches. The IETIC Annual Meeting took place in February. Attendance was approximately 80. Theme of the workshop was economic analysis
and results of tree improvement programs.

Emphasis in the Cooperative has recently shifted somewhat from establishing tests to handling data from test measurements. The Cooperative has established 68 long-term tests and one short-term test. These tests are scheduled for periodic measurement until they reach approximately one-third rotation age. Some tests will be allowed to reach one-half rotation age. Research on Douglas-fir involves a comparison of growth results in a nursery environment as compared to a field environment, and a correlation of results of both over time. Six species are currently under study: Douglas-fir, western larch, grand fir, ponderosa pine, lodgepole pine, and western white pine.

Progress 01/01/81 to 12/30/81
Outputs
Work continues on the six major species of interest to the Cooperative. In the Fall of 1981, 10 genetic tests of western larch were established in western Montana. Each test includes seedlings from approximately 450 families, and occupies approximately 18 acres. These tests will be measured for height and assessed for survival and damage during the Fall of 1982. During Spring 1982, we established 9 field tests of Douglas-fir in north Idaho, and one nursery test in Bonner's Ferry. Each test includes seedlings from approximately 225 families and occupies approximately 8 acres. We requested analysis of data from the ponderosa pine genetic tests established in 1974 from the Forestry Sciences Lab in Moscow. Analysis indicates that seed transfer rules for ponderosa pine in the Inland Empire may be fairly broad, but we urge caution in translating the results into practice since the field tests were established with various types of seedlings, and suffered many
environmental problems during the early years after planting.
