【摘要】 以晋麦50为母本,Gabo为父本组合杂交,研究了其F2子粒的高分子量麦谷蛋白亚基(HMW-GS)的遗传规律,亚基和亚基组合与蛋白质含量及Zeleny沉降值的关系。结果表明:Glu-B1b与Glu-Bli、Glu-D1d与Glu-D1c的遗传符合一对相对基因的分离规律;蛋白质含量与亚基组合相关不显著;所研究的亚基中5+10亚基对沉降值的贡献大于4+12亚基,7+8亚基对沉降值的贡献大于17+18亚基,5+10亚基对沉降值的贡献最大。更多还原

【Abstract】 Jinmai50 as the maternal plant was crossed with Gabo as the paternal plant.The F₂ seeds were used to study the genetic law of HMW-GS and the relationships between subunit combination and the protein content,and also Zeleny sedimentation value.The results showed that the heredity of Glu-B1b and Glu-Bli、Glu-D1d and Glu-D1c conformed to the segregation law.The correlation between subunit combination and their protein content was not significant.The contributions of HMW-GS to Zeleny sedimentation values were determined as the subunit 5+10>4+12,and the subunit 7+8>17+18,the subunit 5+10 has the largest contribution to Zeleny sedimentation value.更多还原
