ABSTRACT Knowledge of the combining ability genotypes, genetic diversity, and heterosis play paramount role in obtaining double-cross hybrids with high productivity. This study was aimed at evaluating these parameters tomato genotypes using partial diallel crosses among commercial single-cross hybrids, which verified possibility for purposes. Tomato included 15 their genitors, two as checks. Of...

Diallel crosses have been used in genetic research to determine the inheritance of important traits among a set of genotypes and to identify superior parents for hybrid or cultivar development. Conventional diallel analysis is limited to partitioning the total variation of the data into general combining ability (GCA) of each genotype and specific combining ability (SCA) of each cross. In this ...

A set of crosses produced by involving 'n' lines in all possible combinations is designated as diallel cross and the analysis of such crosses is known as diallel analysis. Such an analysis provides information on (i) the nature and amount of genetic parameters and (ii) general and specific combining ability of parents and their crosses, respectively. The two main approaches being followed for d...

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...

Diallel mating is a frequently used design for estimating the additive and dominance genetic (polygenic) effects involved in quantitative traits observed in the half- and full-sib progenies generated in plant breeding programmes. Gibbs sampling has been used for making statistical inferences for a mixed-inheritance model (MIM) that includes both major genes and polygenes. However, using this ap...
