OUTPUTS: The new Galletta variety, tested as NCS 93-05, was released from NCSU in 2008. It was awarded US plant Patent PP19,763 in 2009. It was named in memory of Dr. Gene J. Galletta, former NCSU and USDA strawbweey breeder. NCL 03-06 remains the most promising day-neutral selection from NCSU. It is unique among day-neutral strawberry genotypes in that it is resistant to anthracnose fruit rot caused by Colletotrichum acutatum. It is planned for release cooperatively with the new NCSU strawberry breeding program directed by Dr Jeremy Pattison which is headquartered at Kannapolis, NC. Pink flowered day-neutral selection NCL 04-07 continues to look promising as a potential very high quality small fruited specialty variety for homeowners. During the last five years of this project major efforts were made to broaden the genetic diversity in the breeding program by outcrossing to anthracnose resistant Fragaria virginiana accessions from the southeastern and south central US. Parental accessions identified in seedling progenies resulting from these crosses continue to be utilized in crosses in Dr Pattison's new breeding program. PARTICIPANTS: Dr. Frank Louws, Plant Pathologist, NCSU, was the primary collaborator in screening elite NCSU selections for anthracnose fruit rot resistance. Dr. Barbara Smith, Plant Pathologist, USDA, Poplarville, MS, was also a major collaborator in screening seedling progenies for anthracnose resistance.Dr. Richard Hassell, Clemson University, Charleston, SC, collaborated with the program in evaluating elite NCSU selections in coastal South carolina. The North Carolina Strawberry Association provided the majority of the financial support for the day to day operations of the project. TARGET AUDIENCES: North Carolina and southeastern region strawberry growers. Strawberry breeding colleagues around the world. PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
Galletta continues to look promising as a new early season variety with marketable yields similar to standard varieties, and large, firm, very attractive high quality fruit that starts ripening 10 days earlier than Chandler. Galletta is also more tolerant to anthracnose fruit rot than either Camarosa or Chandler. NCL 03-06 and NCL 04-07 are being multiplied from clean source mother plants for potential release in several years. NCL 03-06 will be the first anthracnose fruit rot resistant day-neutral strawberry variety when it is released. Backcross parents involving anthracnose fruit rot resistant Fragaria virginiana in their backgrounds continue to be used to expand the genetic base in the current NCSU breeding program directed by Dr. Jeremy Pattison.

Progress 10/01/08 to 09/30/09
Outputs
OUTPUTS: Strawberry Festival and Chandler were the top performers among named cultivars at Castle Hayne, NC in 2009. NCC 02-25 and NCC 02-63 were top performers among advanced selections and both continue to show promise as potential cultivars. Seedlings consisted primarily of open pollinated progenies from elite female Fragaria virginiana accessions from the southeastern USA. These were prescreened for resistance to anthracnose fruit rot at the USDA Thad Cochran Horticultural Field Laboratory, Poplarville, MS, prior to being established in the field. Therefore selected seedlings are only of utility as parents for broadening the germplasm base in strawberry breeding and increasing the levels of resistance to anthracnose fruit rot. The pink flowered day-neutral selection NCL 04-17 was determined to be very promising as a potential multiple utility cultivar for homeowners. NCL 05-87 was the most promising day-neutral selection with commercial potential. Galletta continues to look good as an early season variety with large very attractive high quality fruit. PARTICIPANTS: The North Carolina Strawberry Association provides the majority of the financial support for the day to day operation of this project. Main collaborators included Dr. Jeremy Pattison, NCSU, and Research Stations in North Carolina, plus Dr Barbara Smith, USDA Horticultural Laboratory, Poplarville, MS. TARGET AUDIENCES: Strawberry growers and breeders. PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
Galletta provides southerstern and middle Atlantic growers with another alternative early season strawberry cultivar that produces very large very attractive high quality fruit. NCL 04-17 is very promising as a potential day-neutral cultivar for homeowners. It produces large very attractive pink floweres all summer in cooler climate regions, and medium size extremely high quality aromatic fruit.

Progress 10/01/07 to 09/30/08
Outputs
OUTPUTS: 2008 was a successful year for the NCSU strawberry breeding program overall. Deer destroyed the selection plots at the Mountain Horticultural Crops Research Center at Fletcher, NC, so no useful information was derived from this location. We did have successful selection evaluation plots at Castle Hayne, Jackson Springs, and Laurel Springs. We also had successful seedling plantings at Both Castle Hayne and Laurel Springs. PARTICIPANTS: Kerry Olive was the technican with the strawberry breeding project. Dr. Frank Louws in Plant Pathology at NCSU continued cooperative screening for anthracnose fruit rot resistance in NCSU breeding selections. TARGET AUDIENCES: Other strawberry breeding programs. North Carolina Strawberry Growers Association. North Carolina and southeastern region strawberry growers. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
Galletta continues to look promising as a new early season variety with marketable yields similar to Camarosa and Chandler in many cases, and large, firm, very attractive high quality fruit that starts ripening 10 days before Chandler. NCC 02-63 is a large size short-day selection that is promising for late season production in plasticulture. It has proven highly resistant to anthracnose fruit rot. NCL 03-06 and NCL 05-87 appear most promising overall among day-neutral selections from the NCSU program, and these are also resistant to anthracnose fruit rot. Sixty four elite new short-day selections were identified among seedling progenies at Castle Hayne, and 68 elite new day-neutral selections at Laurel Springs in 2008.

Progress 10/01/06 to 09/30/07
Outputs
Released strawberry selection NCS 93-05 as Galletta. Determined that day-neutral strawberry selection NCL 03-06 is most promising as a potential new cultivar following virus cleanup. NCL 05-87 and NCL 05-115 are the most promising among recent day-neutral selections and are being established in replicated trials. NCC 02-63 remains promising as a late season short-day type.Fifty-two new selections were identified at Laurel Springs, NC. Completed the first full season performance of strawberry varieties in a high tunnel at Salisbury, NC.
Impacts
The new Galletta strawberry ripens early, before Bish and Camarosa. It produces large very attractive fruit with good firmness and quality. The berries have glossy dark red skin color, medium red flesh, and are conic in shape. It is being released as a high quality cultivar to start the season, but yields are often equal to Camarosa and Chandler. Testing elite day-neutral strawberry selections in western NC has demonstrated the potential for all summer and fall strawberry production in this region. The most promising cultivar during the first year of high tunnel production was Strawberry Festival, which produced over two pounds of marketable fruit per plant over 18 weeks with 30-40 percent of the production during fall and early winter. White and black plastic were equal for total yield, but spring yield was higher on black plastic for most cultivars.
