研究结果表明,小麦突变体“8150321”属早熟、优质类型。经2～6℃、10～30天春化处理和每日6～14小时光照处理,各生育期虽有差异,但反应不敏感,均能正常抽穗结实。早熟性状的主效基因系为二对显性基因。它与早熟品种杂交时,F_2代熟期超亲和早熟类型较多;与中熟品种杂交时,F_2代大多数表现早熟,亦有一定数量的超亲类型;与晚熟品种杂 The results showed that the wheat mutant “8150321” is a precocious and high-quality type. After 2 to 6°C, 10 to 30 days of vernalization and 6 to 14 hours of light treatment each day, although there are differences in the growth stages, the response is not sensitive, and all can normally head and fruit. The major gene of the premature trait was two pairs of dominant genes. When hybridized with early maturing varieties, there were more types of super-affinity and early maturing at F2 generation stage. When hybridized with mid-maturing varieties, most of F2 generations were precocious and had a certain number of super-parental types.
