有人曾首次描述了在普通冬小麦品种无芒1号中减少了胚乳而具有高籽粒蛋白含量的突变体.据进一步的研究表明,该突变体的蛋白质比原品种增加了赖氨酸的浓度,这可能是由于颖果中糊粉层增厚的结果.在普通小麦的蛋白质中还没有发现任何可靠的高赖氨酸含量的资源,因此,这个突变体是很有价值的.突变体M90/8的研究表明,减少了胚乳的突变系是隐性的.我们将黑麦和小黑麦与M90/8杂交,得到了具有减少了胚乳且其蛋白质比它的亲本具有较高的赖氨酸含量的小黑麦系KM5590.
For the first time, a mutant with reduced endosperm and high grain protein content was reported for the common winter wheat variety Wumian No. 1. Further studies have shown that the mutant protein increases the concentration of lysine over the original species, which Probably due to thickening of the aleurone layer in caryopses.This mutant is of great value because no reliable source of high lysine content has been found in common wheat protein.Mutates M90 / 8 Showed that recessions that reduced endosperm were recessive.We crossed the rye and triticale with M90 / 8 to obtain a protein with reduced endosperm and a higher lysine content of its protein than its parent Triticale KM5590.
