| 摘 要： | 为了研究玉米秃尖性状的遗传规律,选取典型的不秃尖自交系Lx9801、Lx00-1、Lx01-3和秃尖自交系Wx04-1、Wx04-2、掖502配制6×6完全双列杂交组合,采用加性-显性-母体效应遗传模型(ADM模型)对试验结果进行分析。结果表明,玉米秃尖性状主要受遗传控制,狭义遗传率为0.6328,广义遗传率为0.9098,并且不存在母体效应;同时秃尖长度与穗长、穗粗、穗行数、行粒数、轴粗都有显著的正相关。

| Abstract: | In order to study the inheritance pattern of maize ear tip-barren,diallel crossing analyses made with 3 non tip-barren parents which were Lx9801,Lx00-1,Lx01-3 and 3 tip-barren which were Wx04-1,Wx04-2,Ye502 was stuied.The results indicated that the tip-barren phenomenon was controlled by genes and there was no maternal effect.The narrow-sense heritability of the tip-barren was 0.632 8 and the broad-sense heritability was 0.909 8.The ear tip-barren length correlated significantly with ear length,ear diameter... |
