These lines will provide NYS growers with more varieties that are productive and adapted to their production needs.The program addresses limiting factors of reliable onion production and quality, particularly the more complicated issues not addressed by company breeders.
The Research OnionAlso map the BLB resistance gene, and use information to develop an.The most advanced lines include both red and brown lines with bulbs approaching commercial size, and improved seed production.An essay about the subtle references to the cold, nature, silence and death that Bradbury has put in this short story.In mid January, the surviving 94 bulbs were taken from storage and are being sprouted.OPPORTUNITIES FOR TRAINING OR PROFESSIONAL DEVELOPMENT One graduate student (Peter Hyde) is in training in the onion breeding program.Impacts Production of brown and red onion lines that are adapted to NY with larger bulb size assist the growers in reliably producing a high quality crop and meeting demand for size over 2.25 inch. Botrytis leaf blight is an important foliar disease on onions in temperate regions around the world.
In 2008 trials new mild onion lines were as mild as mild commercial controls but significantly higher sugar (BRIX) levels, for a firmer sweeter mild onion.The significance of the research onion is an approach to peel away outer layers of the research and arrive at the core.Trial plots are evaluated for stand and maturity in the field, and then for yield and bulb traits by grading at harvest and after brief and longer term storage using standard grading protocols.Three DH hybrids are at least as mild the sibling hybrid Derby and yet have significantly higher BRIX, as well as significantly greater storability.TARGET AUDIENCES: TARGET AUDIENCES One target audience are the seed companies, which use the germplasm produced by this program, as well as the methods developed by this program, to develop commercial onion varieties with improved performance and disease resistance.An OP variety Kasmer Red-BLB was developed with BLB tolerance derived from onion.This demonstrates that the sexual barriers between onion and the wild donar of the resistance have been broken.Martha Mutschler, Darlene DeJong, Stephen Southwick, Peter Hyde, Christina Westerling, Brian Leckie, 2009, Insect and Virus Control Program, 2009, 2008 Report of the Vegetable Breeding Programs, Vegetable Breeding Institute, pp 64 to 78.
In 2008, this included two farms in Elba NY and one farm in Oswego NY TARGET AUDIENCES: OPPORTUNITIES FOR TRAINING OR PROFESSIONAL DEVELOPMENT One graduate student (Peter Hyde) is being trained currently in the onion breeding program.Kasmer Red-BLB has a large dark red bulb, and could be used for organic production.Kasmer Red-BLB was also released to seed companies in the current VBI annual report.Since onions are sprayed approximately weekly for control of this disease, transfer of strong resistance could materially reduce reliance and use of fungicides.
YIX B is a sister line of YIX A with many similar characteristics and YIX F has slightly darker color.Three of these markers are located on chromosomes 1, 6, 7, identifying possible locations for the BLB resistance gene.
An undergraduate summer intern from France (Daphne Bonduelle) was hosted in the lab and worked part time in the onion program and the tomato program to gain experience in vegetable breeding.Written quarterly reports are provided to the Onion Council through Ag and Markets in June, September and December, as well as a final report the following March.D) Evaluate the nature and utility of doubled haploid onion lines produced with materials from all parts of the breeding program in a cooperative project with Lisa Earle.Work is continuing to test single gene control, transfer dwarf stalk trait to male sterile lines, and test the utility of dwarf stalk females to improve onion seed production.Darlene DeJong (Technician working for Mutschler) Dept. of Plant Breeding, Cornell University, Ithaca performs mildness assay on onions, and marker analysis for onion color, and other characteristics.A large number of independently derived double haploid (DH) bulbs, as well as related haploid and tetraploid bulbs, were set for flowering and seed production in summer of 2005.Loss of seed due to lodging of the seed stalk, or scape, is problematic in seed production.
The 2007 BLB field tests, emphasized identification of populations fixed for BLB resistance, so that seed could be generated and released to seed companies.This approach broadened the germplasm base, but also created an issue with contamination of the lines by the yellow bulb allele.
