摘要: 应用植物数量性状主基因+多基因混合遗传模型多世代联合分析方法,研究了爆裂玉米吉爆902(吉812×吉704)的P1、P2、F1、B1:2、B2:2和F2:3 6个世代百粒重的遗传.结果表明:百粒重性状的遗传适合D-2模型,即1对加性主基因+加性-显性多基因模型.爆裂玉米的百粒重是由1对独立主基因控制的加性遗传,主基因的加性效应为d=0.078 ,多基因的加性效应为[d]=079 2,多基因显性效应为[h]=1.49 3.B1:2、B2:2和F2:3 3个世代主基因遗传率分别为12.96%,1.42%和70.33%,多基因遗传率分别为67.63%,34.41%和12.81%.说明B2:2和F2:3世代百粒重表现出较高的主基因遗传率.对吉812-×吉704组合百粒重性状的改良要以主基因为主,同时注意环境的影响.

Abstract: Through applying the genetic model of major gene of plant quantitative traits + poly-gene mixed genetic,we studied the heredity of 100-seed weight of 6 ancestry generation(P1,F1,P2,B1:2,B2:2,F2:3)of JI popping 902(Ji812× Ji704).The results showed that:heredity of 100-seed weight traits conforms to the D-2 model,that was the model of 1 pair of additive major gene and additive-dominant poly-gene.100-seed weight of popcorn was additive heredity which is controlled by 1 pair of independent major gene,additive effect of major gene was d=0.078 5,additive effect of poly-gene was[d] =0.795 2,dominant effect of poly-gene was [h]=1.495 3.The major gene heritability of 3 ancestry generation(B1:2,B2:2,F2:3)was 12.96%,51.42% and 70.33% respectively,and the poly-gene heritability was 67.63%,34.41% and 12.81% respectively.It was revealed that 100-seed weight of ancestry generation of B2:2 and F2:3 showed higher major gene heritability.The improvement of 100-seed weight traits of Ji812×Ji704 combination should focus on the major gene and pay attention to the environmental influences as well.
