摘要:
玉米生育期是决定玉米产量的重要因素。该研究选用玉米品种44长与南无名-8、Mo17与44长、嫩169与44长作为亲本，组配杂交组合，6个世代（P1、P2、F1、F2、B1、B2），分析了各世代从出苗~吐丝的天数及这一生育期的遗传特点。结果表明：各世代的广义遗传力和狭义遗传力都较低，生育期受环境影响较大。模型分析表明：控制生育期的基因符合加性-显性遗传模型，说明加性效应和显性效应是生育期产量性状的主导因子。
Abstract:
The length of maize growth stages is an important factor that decides the maize yield.Six generations of combination(P1,P2,F1,F2,B1,B2)from 3 crosses between the maize 44 long and south unknown-8,Mo17 and 44 long,Nen 169 and 44 long were used to analyze the genetic characteristics of the growth stages from a seedling to spin silk of day count.The results showed that the broad sense heredity and narrow senses of the generations were all very bow,the length of maize growth stages was influenced greatly by the environment.The model analysis showed that the gene that control maize growth stages matches to additive-dominant heredity model,and additive effect and dominant effect is predominant factor that control to the yield traits.
