Sesame (Sesamum indicum L.) is a drought tolerant oilseed crop with the highest oleic acid content, which isyet to be explored for its hybrid vigour. Therefore, present study was carried at Sri Karan Narendra AgricultureUniversity, Jobner, Jaipur, Rajasthan during 2019–20 and 2020–21 combining ability 11 seed yieldand attributing traits in 10 parents their 45 crosses sesame. The effects of gene...

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...

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....

Abstract Oilseed rape ( Brassica napus L.) is sensitive to heat stress during the reproductive stage, but it not clear whether male and female organs differ in their sensitivity stress. In this study, full diallel crossing experiments were conducted among four genotypes of B. under control, moderate high conditions for five days immediately before two after crossing. General combining ability (...

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 ...

Interspecific hybrid Cucurbita rootstocks (Cucurbita maxima × moschata) are the most widely used for Cucurbitaceous vegetables in world. In recent years, scientists have focused on understanding and exploiting root architectures as new opportunities crop improvement. Selection of parents hybrids based combining ability test is an effective approach interspecific variety breeding. However, limit...

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...

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...

To identify optimal mating combinations for Litopenaeus vannamei , a linear mixed model was used to estimate the general combining ability (GCA) and specific (SCA) growth multiple stress tolerance [high salt (35‰), low pH (6 ± 0.1), high ammonia nitrogen (70 mg/L) co-stress] traits in 47 of L. . The results showed that SCA parents played dominant role offspring traits. highest GCAs were observe...

general combining ability of sugar beet parents were determined for different quantity and quality characteristics.forty six sugar beet hybrids obtained from crosses of 23 diploid pollinators with two male sterile parents as tester together with three checks were evaluated for 10 important agronomic and technological characters at kamalshar research station in karaj in 2004.experiment was carri...
