Blackgram is the grain legume crop mainly grown in variable edaphic and weather conditions India resulting less productivity. However, yield of blackgram can be improved by breeding methods involving potential parents analysing combining ability. A set three female (CO 5, CO 6 ADT 5) six male (MASH 1008, VBN 6, 8, 9, 10 11) were used as parents. The crosses synthesised Line × Tester fashion the...

A study was conducted to determine the types of gene action different yield-related traits in tomato and combining ability four advanced lines. The heterotic response hybrids also assessed. Analysis variance (ANOVA) revealed significant differences (P ≤ 0.05) among all traits. General (GCA) specific (SCA) for chosen were computed using Griffing’s approach diallel. Combining additive non-additiv...

Knowledge on gene action and trait expression are important for effective breeding. The objective of this study was to determine the general combining ability (GCA), specific combining ability (SCA), maternal effects and heritability of drought tolerance, yield and yield components of candidate sweetpotato clones. Twelve genotypes selected for their high yield, dry matter content or drought tol...

to evaluate general and specific combining ability for resistance to bolting and cercospora leaf spot, 36 hybrids derived from crosses between 9 sugar beet lines along with four checks were planted in safiabad agricultural research center (dezful) in 2008-2009. the experimental design was a triple lattice design with three replications. analysis of variance showed significant differences among ...

This study was carried out to estimate general combining ability (GCA) and specific (SCA) of pre-and post-weaning traits from a partial diallel cross in three rabbit breeds: Local (L), Flemish Giant (F), Rex (R). Body weight at 0 (BW0), 30 (BW30), 42 (BW42), 63 (BW63) days age, average daily gains d age (ADG0-30), (ADG30-42), (ADG42-63), (ADG30-63), litter size birth (LS0) weaning (LS42), morta...

Advanced button mushroom cultivars that are less sensitive to mechanical bruising are required by the mushroom industry, where automated harvesting still cannot be used for the fresh mushroom market. The genetic variation in bruising sensitivity (BS) of Agaricus bisporus was studied through an incomplete set of diallel crosses to get insight in the heritability of BS and the combining ability o...

a study was conducted on genetics of some important agronomic traits (number of productive tillers per hill, plant height (cm), panicle length (cm), number of spikelets per panicle and 100-grain weight) in rice during 2012-13. two lines were crossed with five testers in line × tester fashion to produce 10 f1 hybrids. analysis of variance revealed significant differences among genotypes and cros...

General and specific combining ability effects are important indicators in a maize (Zea mays L.) breeding program aiming hybrid development. The objectives of the present study were to estimate the general (GCA) and specific combining abilities (SCA) effects of commercial maize hybrids using a complete diallel scheme and to assess the stabilities of these estimates. Fifty-five entries were asse...

Heterosis and combining ability are two important considerations in the utilization of heterosis, which can be used to generate excellent hybrid resource candidates is very conventional breeding. In this study, ability, heritability, heterosis eight major agronomic traits were analyzed 10 tomato parents 45 crosses between them. As well as TY-301, a recognized official variety that currently sel...

Aims: To estimate the effects of general and specific combinatorial fitness in parents progeny on yield fruit quality related traits melon.
 Study Design: A completely randomized block design with three replications was used to analysis variance combining ability (GCA) (SCA). The genetic carried out based Griffing Method II dialelic (1956) fixed model. Tukey P=.05 mean comparison analysis....
