Abstract

The photoperiodic response of F1 and its parents was analyzed, and the
photoperiodic response and short photoperiod sensitive male sterility of F2
progenies were studied in this paper. The results showed that the strong
response was dominant over the weak response to photoperiod. The photoperiodic
response of plants with short photoperiod sensitive male sterility in F2 was
above medial degree(the rate of heading acceleration > 15%). Photoperiodic
response showed a positive correlation with short photoperiod sensitive male
sterility. The main sterility genes of Yid1s and Yid2s were allelism. It can be
inferred that the short photoperiod sensitive male sterile gene might be
expressed upon the presence of the photoperiodic response genes, and that the
short photoperiod sensitive male sterility of plants with the same genes could
differ in their reproductive expressions, not because of the changes of the
genes, but the difference in genetic backgrounds of photoperiodic response.
