Impacts
Windsor and Sante Fe Southern Highbush blueberry cultivars are the earliest maturing of the eighteen lines in this trial. Several peach breeding lines with white flesh and high sugar to acid ratios have been identified for advanced trials and evaluation. Development of late season ripening cultivars was a major objective of the peach breeding program and several selections with cultivar potential have been identified. Peach breeding selections,L96-a5-1,L96-a4-1,L96-a5-51 and L85-a13-54 have been identified for release as named cultivars. The latest maturity selection is L85-13-54 which ripens the second week of August and demonstrates good marketing traits. These selections represent maturity ranges from very early to three weeks later than any currently recommended cultivar. All selections are well colored and with firm flesh to meet local and long distance market criteria. The late-maturing selections have at least fifty percent red overcolor and an average fruit diameter of 7cm. The chilling unit requirement for late varieties is about 500 hours which would allow its area of for adaptation to central Louisiana and similar production areas. Another selection, L96-A4-62, a seedling of the 'Ouachita Gold' cultivar, ripens about the last week of July with large 7 to 8 cm diameter fruit and has very good attributes for local markets.

OUTPUTS: Data collected from fruiting characteristics of promising peach and plum varieties growing in trials at Idlewild and Burden Research stations has enabled us to construct a new variety recommendation list for southern and coastal Louisiana. Results of these trials were reported at regional horticultural forums. These data will be made available on station websites. Southern Highbush Blueberry evaluation trials at the Burden Research center have identified four early varieties with very high quality fruit. Results were reported at regional horticultural forums. PARTICIPANTS: Charles E Johnson, PI TARGET AUDIENCES: Target Audiences are fruit crop producers, extension agents and market gardeners PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
The major goals of the fruit research program have been to develop and identify fruit varieties adapted to south Louisiana conditions. Fruit characteristics of varieties and breeding lines are carefully scrutinized for fruit characteristics that would be suitable for local markets. We have identified five very low chill peach varieties that can be used for fresh market production in southern and coastal Louisiana. Gulf King, Delta, Gulf Crest and Gulf Prince can increase marketing opportunities for south Louisiana growers. These varieties will offer larger, sweeter fruit with more red color than those currently recommended. Southern highbush blueberries offer an opportunity for fruit growers in coastal Louisiana to expand marketing potential for early season (April and May) fruit. Many new varieties have been released from breeding programs in southern US. We have selected four potential varieties from a variety trial planting of eighteen varieties at the Burden Research Center. Windsor, Santa Fe, Millennium, and Biloxi varieties all ripened in mid April with large good quality berries. A recommended list of adaptable Southern Highbush varieties will be published after additional seasons of observations.

Impacts
One of the major goals of the peach breeding program from the beginning in the 1950's was to develop late season ripening peach cultivars with good marketable traits such as uniform red color and fruit diameter size of 6 to 8 cm diameter. The use of the pollen parent, Ouachita Gold, peach has contributed to late season ripening and fruit size when crossed with mid season ripening selections such as L96-A4-62. One outstanding seedling, L85-A14-54, ripened the second week in August with over fifty percent red overcolor and diameter of 7mm and very good eating quality. Extension of the harvest period with late season, late July and August, peach varieties would increase the marketing opportunities for Louisiana growers.There are no currently recommended peach varieties that ripen in late season with low chilling hour requirements. Nine low chill 250 to 450 chilling unit requirement peach cultivars were evaluated for commercial potential. Of the nine cultivars planted in
2004 and 2005 only five fruited in 2007.Gulf King ripened the first week of May with a full crop of round fruit averaging 5.6 cm diameter. Gulf Crest, Florida King, Gulf Prince, and Delta ripened in 5 to 7 day intervals, respectively. Florida King was the only cultivar that did not produce a full crop of fruit in 2007. The fruit of Fla. King contain split pits and were not marketable. Southern Highbush Blueberries: Eighteen southern highbush blueberry cultivars were evaluated in raised beds. New Southern Highbush Blueberry (SHB) varieties developed by the USDA and University of Florida offer a potential new crop for southern Louisiana. The earliest maturing cultivar in 2007 was Windsor the third week of April. Berries from Sharpeblue, Sante Fe, Star and Bluecrisp were ripe by the first week in May. Sharpeblue and Biloxi produced the highest yield of berries per plant with 4.2 and 1.8 kg per plant, respectively. The most vigorous plants were Sharpeblue, Jubilee, Biloxi and Jewel with
vigor ratings of 4.5/5.0 and higher. Mortality rates were highest among plants of Misty and O'Neal with 60% dead. The best survival rate was with Jubilee, Sharpeblue, Windsor and Jewel with 90% survival.These varieties require low chilling hours and produce large marketable fruit. SHB varieties ripen extremely early (April and May) and offer growers a chance a high market prices at a time when competition from other blueberry growing areas would be very low.

Progress 01/01/06 to 12/31/06
Outputs
Peaches: Sixty eight advanced peach selections were evaluated for fruiting characteristics alongside recommended cultivars. Two early season selections, L77-A60-13 and L96-A4-1 ripened the third week of June and had fruiting characteristics superior to any existing recommended cultivar. L96-A4-62, exhibited good red fruit color and size for a late season ripening selection. One of the major goals of the peach breeding program from the beginning in the 1950's was to develop late season ripening peach cultivars with good marketable traits such as uniform red color and mature fruit diameter size of at least 6 to 8 cm diameter. The use of the pollen parent, Ouachita Gold, peach has contributed to late season ripening and fruit size when crossed with mid season ripening selections such as L96-A4-62. About one hundred and fifty seedlings from controlled crosses fruited for the first time and were evaluated for ripening time and fruit quality. Twenty five seedlings were
selected for further evaluation of fruiting characteristics. Southern Highbush Blueberries: Eighteen cultivars were planted in raised beds at Burden Research Center during spring 2005. The purpose of this experiment was to identify early ripening cultivars with market potential. The growing media consists of 30 cm of aged pine bark. Plants were irrigated daily during the growing season. The earliest maturing cultivar in 2006, Windsor, had berries the first week of April. Berries from Sharpeblue, Sante Fe, Star and Bluecrisp were mature by the third week of April. Sharpeblue and Jewel produced the highest yield of berries per plant with 4.2 and 1.8 kg per plant respectively. Berry weight was fairly consistent among cultivars at about 4 g per fruit. The most vigorous plants were Sharpeblue, Jubilee, Jewel and Biloxi with vigor ratings of 4.5/5.0 and higher. Mortality rates were highest among plants of Misty and O'Neal with 60% dead after the second growing season. The best survival rate
was with Jubilee, Sharpeblue, Windsor and Jewel with 90% survival.
Impacts
Extension of the harvest period with late season, late July and August, peach varieties would increase the marketing opportunities for Louisiana growers.There are no currently recommended peach varieties that ripen in late season with low chilling hour requirements. New Southern Highbush Blueberry (SHB)varieties developed by the USDA and University Of Florida offer a potential new crop for southern Louisiana. These varieties require low chilling hours and produce large marketable fruit. SHB varieties ripen extremely early (April and May)and offer growers a chance a high market prices at a time when competetion from other blueberry growing areas would be very low.
