Cotton is India’s most important cash crop and it used for agricultural industrial purposes all over the world. The greatest way identifying superior hybrids best combiners of parents by L×T design. For analyzing combining ability heterosis various yield attributing variables as well quality traits, viz., four lines testers were crossed to produce sixteen hybrids. MCU5 × KC3 cross contributed p...

A study was conducted to determine gene actions controlling yield and other qualitative traits of tomato (Lycopersicon lycopersicum) as well combining ability among selected genotypes at the Teaching Research Farm Ladoke Akintola University Technology, Ogbomoso during 2017 2018 cropping seasons. Five ten offspring (F1), obtained from a 5×5 diallel crosses were sown in plots, arranged Randomized...

Six diverse homozygous parents, BWR-1, BWR-6-1, BWR-29, BWR-39, EC-464107 and EC-464115 were evaluated for gene action, heritability combining ability using 6X6 diallel cross excluding reciprocals. The results showed that analysis of variance revealed significant differences due to crosses parent’s vs crosses. Mean squares GCA SCA all traits days 50% flowering, first picking, plant height, prim...

to study general and specific combining ability of some rice varieties for grain physical properties and milling quality, a diallel design with five parents (hashemi, vandana, kadous, shahpasand and ir36) was used. parents and their f1 progenies (25 genotypes) were grown in a randomized complete blocks design with three replications in the research field of rice research institute of iran (rrii...

Global efforts are underway to biofortify cassava (Manihot esculenta Crantz) with provitamin A carotenoids to help combat dietary vitamin A deficiency afflicting the health of more than 500 million resource-poor people in Sub-Saharan Africa. To further the biofortification initiative in Uganda, a 6×6 diallel analysis was conducted to estimate combining ability of six provitamin A clones and gen...

Diallel analysis assumes that the genetic interactions contributing to trait variation can be adequately captured by GCA and SCA effects. However, in reality, more complex, involving higher-order epistatic interactions, pleiotropy, other factors are not accounted for traditional diallel analysis, this purpose, studies were conducted study combinatorial ability of wheat varieties widely planted ...

Downy mildew (Plasmopara viticola) and anthracnose (Sphaceloma ampelinum) are two of the major diseases of most grapevine (Vitis vinifera L.) cultivars grown in Thailand. Therefore, breeding grapevines for improved downy mildew and anthracnose resistance is crucial. Factorial crosses were made between three downy mildew and/or anthracnose resistant lines ('NY88.0517.01', 'NY65.0550.04', and 'NY...

Heterosis and combining ability for total number of eggs laid per female silkworm Bombyx mori L were investigated in a six parent diallel crossing programme in four rearing seasons. Magnitude of heterosis varied from seasons to season and was not consistent over characters. Effect of season was important in the expression of genetic variances and other parameters studied. Considerable amount to...
