摘要: 以墨白962的不同世代为材料,研究了混合选择对热带玉米群体穗分化的选择响应。结果表明,在混合选择过程中,雄穗的穗分化阶段I、IV和V所用时间在的C0、C2和C4等3个世代之间无显著性差异;但是雄穗的分化阶段II和III所用时间在世代C0和C4之间有显著差异。而穗子的穗分化阶段I和II在C4、C0和C2世代之间有显著差异。对于雄穗和穗子相同穗分化阶段的时间差,在不同世代之间无显著差异。

Abstract: To understand the selection-response of the characters on spike differentiation among different generations by mass selection under temperate, in Guanzhong Plain, Shaanxi province, tropical maize population Mobai 962 was used. The result are as follows: Internal of differentiation phase I, IV and V during tassel development, there is no significantly difference among different generations C0, C2 and C4; there are significant difference at phase II and III between generation C0 and C4. There are significant differences at ear differentiation phase I and II among generations C4 and C0, C2. There are no significant difference about the internal of tassel and ear at the same differentiation phase.
