摘  要:
研究了287个“Lemont/特青”重组自交系的六个籼粳分类性状(程氏指数法)和154个RFI.P位点的遗传组成。群体的六性状总分呈连续分布,略偏向粳型,该方法将把大部分株系分入籼粳中间类型。遗传组成的分布略偏向特青并有更多的极端株系,六性状总分和分子标记的相关不明显。还就单个性状的分布和性状间重组情况,以及不同性状间及其与总分间的相关关系进行了分析。

摘  要:
Segregation and recombination of six characteristics in 287 Rils of Lemont/Teqing were investigated using Cheng's indica/japonica rice classification index. The population has a continuous distribution of total value, a little inclining to japonica type. Most of the Rils were classified into intermediate type. The genetic compose according to 154 RFLP loci had a distribution with more extreme individuals, a little inclining to Teqing. There was a low correlation between the Cheng'S total value and genetic compose. The distribution, recombination of different characters and the correlation between different characters and total value was also analyzed.
