Results of quantitative measurements and genetic study on the capsaicin content of pepper fruit showed that a significant negative correlation was found between cansaicin content and fresh weight of fruit, and capsaicin content, possessing a comparatively high heritability, predominantly determined the expression of this characteristic in the hybrid progeny through its general combining ability. It is considered that conventional breeding method would be competent enough and single plant selection in the early...

Results of quantitative measurements and genetic study on the capsaicin content of pepper fruit showed that a significant negative correlation was found between cansaicin content and fresh weight of fruit, and capsaicin content, possessing a comparatively high heritability, predominantly determined the expression of this characteristic in the hybrid progeny through its general combining ability. It is considered that conventional breeding method would be competent enough and single plant selection in the early generations would be rather effective. In the selection of parents for F_1 utilization, the general combining ability of the parent lines should be considered as the important criterion.

本文对辣椒果实中辣椒素含量进行了定量分析;研究了辣椒素含量与果实重量的相关性;以及辣椒素含量的配合力和遗传力。试验结果表明:辣椒素含量与果实鲜重呈显著负相关,辣椒素含量性状的遗传力较高,而且又以一般配合力对杂种后代遗传表现的影响占主导地位,因此应用常规育种途径较为有利,并且在早期世代进行单株选择,可以得到较高的选择效果。在应用F_1代杂种优势育种时,可以在很大程度上根据亲本系统的一般配合力效应值作为选配亲本的重要依据。

The main quantitative characters of 16 hybrids crossed with their parents were studied using incomplete biseral cross.The combining ability,hereditary effects and heritability were estimated.The experimental results showed that the com- bining ability was different among characters of different parents.Early maturity of cucumber was controlled by nonadditive effect.Its narrow sense heritability was low,but the additive heritary was the main in total yield and the percen- tage of female flowers.The female flowering...

The main quantitative characters of 16 hybrids crossed with their parents were studied using incomplete biseral cross.The combining ability,hereditary effects and heritability were estimated.The experimental results showed that the com- bining ability was different among characters of different parents.Early maturity of cucumber was controlled by nonadditive effect.Its narrow sense heritability was low,but the additive heritary was the main in total yield and the percen- tage of female flowers.The female flowering period of the population depended chiefly on the genotypes.Total yields,the percentage of female flowers,speed of fruit growth and development and the variations in ihe length of fruits are greatly affected by the environment.The heterosis of early maturity is more im- portant than the yields in heterosis breeding in cucumber.Quantitative characters are closely related to breeding.Studying the combining ability of major quantita- tive characters,hereditary effects and gene functions of cucumber parent self- bred lines will provide scientific bases for hybrid vigor matching,selection of quantitative characters and progress of hybrid offsprings.

采用不完全双列杂交法,研究了黄瓜八个亲本系所配十六个组合的主要数量性状,对配合力及其相应的基因型效应、遗传力进行了估算分析。试验表明:不同亲本间各性状的配合力有差异;早熟性以非加性遗传为主,狭义遗传力较低,总产量、雌花节率以加性遗传为主;群体雌花开放期主要取决于基因型。总产量,雌花节率、瓜条发育速度、瓜条长度的变异受环境影响较大,杂种优势育种对早熟性比丰产性更重要。

A diallel crossing design which contained seven parents of Cunninghamia lanceolata was carried out. From statistical analysis of general and special combining ability, effect in back and self crossing, and heterosis of five characters--height, breast-diameter, numbers of knot and branch, crown-diameterin four year's Cunninghamia lanceolata, the results obtained are as follows: (1) These five quantitative characters are mainly controlled by the effect of general combining ability; (2) There are also some effect...

A diallel crossing design which contained seven parents of Cunninghamia lanceolata was carried out. From statistical analysis of general and special combining ability, effect in back and self crossing, and heterosis of five characters--height, breast-diameter, numbers of knot and branch, crown-diameterin four year's Cunninghamia lanceolata, the results obtained are as follows: (1) These five quantitative characters are mainly controlled by the effect of general combining ability; (2) There are also some effect of special combining ability and back crosses among the detinite parent's combinations; (3) Chinese Fir has considerable self-crossing rate but its failing effect is common, which we should pay attention to avoid or apply in the practice of breeding good strains and in the study on long term breeding; (4) It appears frequently the super-parent positive heterosis. These heterosis often related to general combining ability which could be acted as a standard of selecting parent when we make use of heterosis to breeding.

7个杉木亲本按全双列交配设计,对4年生杉木的树高、胸径、枝盘数、分枝数及冠幅的一般配合力、特殊配合力、反交效应、自交效应及杂种优势作了分析和计算。结果表明:①5个数量性状主要受一般配合力效应所控制,②在特定亲本的交配组合间特殊配合力及反交效应也有一定影响;③杉木具有较高的自交率,但衰退是普遍的,在良种繁育及长期育种中应予注意避免或利用;④在杉木杂交组合中,常出现超亲正向杂种优势,这些杂种优势多与亲本的一般配合力有关。在利用杂种优势的育种中,一般配合力可作为选择亲本的一个标准。
