摘要
栗中的直链淀粉含量是由主基因和修饰基因共同控制的,它不受细胞质基因及胚乳基因的影响。控制直链淀粉含量的基因分离完全符合孟德尔的独立分配规律。高直链淀粉含量表现为部分显性和完全显性,并因不同的遗传背景表现不同。控制直链淀粉含量的基因除存在加性、显性效应外,还存在加×加、显×显效应,并且不适合双基因互作的模型测验。
The content of straight chain starch in Setoria Italica (L.) Bear, was controlled by one major gene and one modifying gene, It was not affected by cytogene and endosperm gene, The segregation of genes followed Mendel's 'principle of independent assortment', The content of high straight chain starch in Setaria Italica (L.) Bear, was partially dominant or completely dominant in different crosses, There were additive×additive effect and dominant×dominant effect in the contents of straight chain starch in Setaria Italica (L, ) Bear., except additive effect and dominant effect, It did not fit the digenic interaction model,
