study on relationships between yield and its components will improve the efficiencyof a breeding program with appropriate selection criteria. in this study,interrelationships between yield and its components in cantaloupe were investigatedusing sequential path coefficient analysis. to determine important components of yieldin cantaloupe, 49 genotypes generated from 7 × 7 diallel, were evaluated...

A set of 29 genotypes including 7 parents, their 21 resultant hybrids and one commercial check variety (Arka Mangala) were sown during summer, 2019 at the College Instructional Farm, Horticulture, Venkataramannagudem to study magnitude heterosis using half diallel analysis for eleven characters. Significant differences observed among parents indicating considerable genetic variation these genot...

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...

Background: A study was carried out to estimate the general and specific combining abilities, as well heterosis for seed yield associated traits in pea lines. Methods: Twenty-eight cross combinations were generated using half-diallel mating design with eight parental The mean values of its contributing lines their offspring each replication used statistical analysis viz., GCA, SCA Heterosis. Re...

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 ...

The term diallel is a Greek word and implies all possible crosses among a collection of male and female animals. Hayman (1954a, 1954b) defined diallel cross as the set of all possible crosses between several genotypes, which may be individuals, clones, homozygous lines, etc. Diallel cross is most balanced and systematic experiment to examine continuous variation. The genetic information related...

T H E diallel cross method of investigating the genetical properties of a group of homozygous lines has recently received much attention. HULL (1945) has considered some aspects of the method. A short summary of a more general approach by JINKS and HAYMAN (1953) and its application to several published sets of maize data has also appeared. In another paper JINKS (1954) has described experiments...

Twenty one F2 progenies derived from a 7×7 diallel crosses along with parents were evaluated for grain yield, flowering and maturity time. Due to significant genotypic effects for all traits, genetic analyses were performed on F2 progenies including analyses of combining ability and genetic components. The Analysis of variance revealed that both additive and non-additive genetic effects were in...
