Última Increased grain dormancy in white-grained wheat by introgression of preharvest sprouting tolerance QTLs OAK Kottearachchi, NS; Uchino, N.; Kato, Kiyoaki; Miura, Hideho; 加藤, 清明; 三浦, 秀穂. White-grained wheat cultivars have long been recognized to be less resistant to preharvest sprouting (PHS) than the red-grained ones. Previously two QTLs for grain dormancy, QPhs.ocs-3A.1 (QPhs-3AS) and QPhs.ocs-4A.1 (QPhs-4AL) were identified in a highly dormant Japanese red wheat, Zenkoujikomugi (Zen). Aiming at improvement of PHS tolerance in white-grained wheat, the introgression effect of these two QTLs in a white-grained population consisting of 40 recombinant inbred lines (RILs) developed from a cross between Zen and white-grained Spica was examined here. Random 20 RILs with red grains were also developed from the same cross and used as a control population. The RILs were grown in the field and in the glasshouse to evaluate the grain dormancy by...

Ano: 2006 URL: http://ir.obihiro.ac.jp/dspace/handle/10322/714 Mapping QTLs for grain dormancy on wheat chromosome 3A and the group 4 chromosomes, and their combined effect OAK Mori, M.; Uchino, N.; Chono, M.; Chono, K.; Miura, Hideho. A major QTL for grain dormancy, QPhs.ocs-3A.1, derived from the highly dormant wheat Zenkoujikomugi (Zen), has been identified in a study made under a controlled environment. Further investigations were needed to dissect the precise position and expression of QPhs.ocs-3A.1 under different field conditions because the ability to detect genetic loci for grain dormancy traits is compromised by environmental effects and genotype/environment interactions. Group 4 chromosomes have also been shown to be possible sites of QTLs for grain dormancy. The objectives of this study were (1) to locate additional molecular markers in the QPhs.ocs-3A.1 region, (2) to identify QTLs on the group 4 chromosomes and (3) to elucidate their combined effects. We examined the... Palavras-chave: QUANTITATIVE TRAIT LOCI; CONTROLLING SEED DORMANCY; BREAD-WHEAT; MAJOR GENES; RICE; MICROSATELLITE; IDENTIFICATION; GROUP-4; WEIGHT; L.
