  genetical parameters

Genetical parameters estimated from DH and F3 samples have successfully been used to predict the number of inbred lines transgressing the parental range for β-glucan content and bivariate combinations involving β-glucan.
      


It has been proved that, under the circumstance of half diallel cross, the dominant variation components obtained by using it in the estimating formula of the full diallel cross are a bit high,which does not have obvious influence on the estimation of genetical parameters. It will not bring about large deviation to replace the full diallel cross designs with half diallel cross designs, in estimating genetical parameters.

本文从理论和实例两方面证实:在半双列杂交情况下,用于全双列杂交的估计式所得显性变异分量偏高,但这种偏倚对遗传参数的估值,一般不会有明显影响,若无正反交效应或正反交差异不大,在估计遗传参数时,用半双列杂交代替其相应的全双列杂交设计,不会产生太大的偏差。

Five tomato varieties (Yizhuang No. 2, 402, 854, Xifeng No. 1 and Jubilee) were used to determine and study thecombining ability, heterosis, correlation and genetical parameters of lycopene,carotene, ascorbic acid and soluble solid contents of ripened fruit. The genetieal models of Lycopene, carotene and ascorbic acid were given by the analytic method of diallel crosses design. The results are summarized as follows: There is significant difference among the general combing ability effects (GCA) of the four quality characters. The special combining ability effects (SCA) are significantly different among genotypes and in harvest dates. The lycopene content shows positive heterosis but carotene content shows negative heterosis. Both ascorbie acid and soluble solid are insignificant. The heredity of lycopene and carotene can be explained by the additive dominative genetical model. The heritabilities of lycopene and carotene are higher, whereas that of ascorbic acid and soluble solid are lower.

选用意庄2号、402、854、锡粉1号、桔黄佳辰5个番茄红素含量呈梯度差异的品种为试材,分5个采期,测定成熟番茄果实中番茄红素、胡萝卜素、抗坏血酸、可溶性固形物含量等4个品质性状。结果表明:各性状的一般配合力效应比较稳定,特殊配合力差异较大;番茄红素、胡萝卜素均表现出明显的超中优势。并应用双列资料的遗传模型分析方法估算出番茄红素、胡萝卜素2个性状基因遗传属加性-显性模型;推算出各亲本品种的番茄红素、胡萝卜素、抗坏血酸性状的显、隐性基因分布趋势。
