Abstract
To understand the effect of male gametophyte selection caused by different grown altitude environment, the male
gametophyte genotype selection populations generated by cross between one cold tolerance
japonica
landrance Xiaomagu and one
subspecies progeny Nan34 under three different altitude condition. Eleven morphological characters and seven molecular loci of
these selection populations grown at the environments were analyzed, and found significant genetic segregation distortions of these
characters and loci. It was also screened difference of selection effect derived from differ grown condition. There were appeared the
lowest Shannon-Weiner diversity for seven characters and significant genetic segregation distortion for seven loci at altitude 2 200
meters where grown cold tolerance
japonica
rice. At altitude 1 250 meters grown
indica
rice area had one characters and six loci,
respectively. However, it was found the highest diversity for five characters and significant genetic segregation distortion for five loci
at altitude 1 860 meters where grown
japonica
rice. Anyway, it could be occurred the selection among rice male gametophyte
genotypes under different altitude environmental pressure, and the trend was 2200m
1250m
1860m.
