核质互作对不育系后代农艺特性的影响 从我们1972—1977年的试验材料中清楚地看到核质互作对不育系后代农艺特性的影响。首先从抗寒性来说,1976—1977年北京冬寒较著(雪少),加以我们的田间管理失误(未浇冻水),造成冻害植株大量死亡;由于这种意外情况,使品系间以及核质相互作用间的差异变得更加明显。如表1所载。在第1组的[(MS苏早×北14)
Effect of nucleus-cytoplasmic interactions on agronomic characteristics of the progenies of the male sterile line It is clear from our experimental material from 1972 to 1977 that the effect of the nuclear-cytoplasmic interaction on the agronomic characteristics of the progenies of the sterile lines. First of all, from the perspective of cold resistance, the severe cold winter in Beijing from 1976 to 1977 (less snow) allowed us to make mistakes in field management (without pouring frozen water), resulting in a large number of cold-killed plants. As a result of this accident, As well as the differences between nuclear and nuclear interactions become more apparent. As shown in Table 1. In the first group of [(MS Suxu Xibei 14)
