Tools for yield prediction are requisite to any successful heterosis breeding program. With this objective present investigation was designed to work out the relationship between genetic diversity, heterosis and specific combining ability (SCA) and yield for predicting the potential F1 combinations in maize. A field experiment consisting of 10 inbreds of diverse origin and their 45 crosses was ...

The objective of the present study was to correlate the genetic distances (GD) of single cross hybrids with yield, heterosis and specific combining ability (SCA) in the double cross hybrid synthesis. For this, 10 single cross commercial hybrids were used from different companies, and all the possible double hybrids were synthesized by a complete dialell. The hybrids were assessed in 15 location...

In asparagus, current cultivars are mostly hybrids (known as clonal hybrids) derived from crosses between two parents, female and male, with good combining ability. Despite the fact that have been obtained for more than 40 years, studies of heterosis abilities involved limited. Similarly, there no published regarding association genetic divergence heterosis. this sense, we evaluated sets dialle...

Proper understanding of the mode gene action in open-pollinated varieties (OPVs) maize parents helps breeder choice appropriate breeding method to improve its genetic value. The objectives present study were determine controlling grain yield and other agronomic traits late maturing elite OPVs classify into heterotic groups. Ninety-one hybrids generated from 14 OPV using diallel mating design ev...

The combining ability analysis using Line × Tester model was conducted in chickpea to know the general and specific combining ability of the distingushing parents and their crosses, respectively and to select best material for further breeding programme and generation advanceme- nt. Two genetically diverse testers viz., JAKI-9218 and ICCV-2 as females and 8 males viz., HC-5, ICC-506, PKV Harita...

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...

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...

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 ...
