摘要
选用4个材料亲本,按4×4NCⅡ完全双列杂交设计,配制了12个组合,对小麦植酸含量的杂种优势及其遗传力进行了研究。结果表明,偃展4110×淮麦20的中亲优势和超低亲优势最大,偃展4110×CN8081的中亲优势最小,CN8081×小偃986的超低亲优势最小;淮麦20的一般配合力效应值最大,小偃986的特殊配合力效应值最小;植酸的广义遗传力为85.9%,狭义遗传力为32.3%。
Heterosis and Hereditary of Phytic acid in wheat were studied with 12 crosses from 4 parents by 4 × 4NC Ⅱ complete diallel crossing design. The result showed that over mid - parent heterosis and over low - parent heterosis of Yanzhan4110 × Huaimai20 in F1 is the strongest, over mid - parent heterosis of Yanzhan4110 × CN8081 in F1 is the least, Over low -parent heterosis of CN8081 x Xiaoyan986 in F1 is the least;the general combining ability value of Huaimai20 is the biggest and specific combining ability of Xiaoyan986 is the smallest; Broad heritability of phytic acid was 85.9% ,while narrow heritability of phytic acid was 32.3%.
