【摘要】 以中秆弯曲穗型品系９０３０和半矮秆直立穗型品系沈农８７１４杂交，Ｆ２代株高、穗型分布频率分析结果初步表明，株高应受１个显性基因及其它基因控制，穗型应受１个加性基因及其它基因控制。半矮生性和穗直立性之间存在一定的相关性。更多还原

【Abstract】 The frequency distributions of culm length and panicle type for F 2 generation in the cross between normal line,9030,with curved panicle and simidwarf line,Shennong 8714,with erect panicle indicted that the length might be cntrolled by a dominant gene and others,and the panicle type might be controlled by an additive gene and others There was a positive correlation between culm length and panicle type更多还原
