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...

Elephant grass is a tropical forage plant widely distributed throughout Brazil. It was first exclusively used in the livestock sector as cattle feed. The grass is characterized by its high productivity and photosynthetic capacity and is considered as an alternative source of renewable energy. Here, we estimated the general combining ability of the parents and specific combining ability of the h...

production of high rapeseed yield is important in rapeseed breeding programs. with regards to the importance of estimation of general combining ability (gca), specific combining ability (sca), additive and dominance genetic variances, gene action, heterosis and heritability, an experiment was carried out in a 9×9 diallel design. nine parents with 36 crosses were studied in a randomized complete...

In this study, conducted in two different seasons, we aimed to choose parents to obtain promising segregating populations for the extraction of black bean (Phaseolus vulgaris L.) lines that are superior in terms of disease resistance, plant architecture, and grain yield. Twelve parents were arranged in two groups to compose a partial diallel in a 5 x 7 scheme. Group 1 was composed of parents wi...

Combining ability and gene action for quality and nutrient uptake of okra (Abelmoschus esculentus L.) were studied following full diallel mating analysis using five pure lines viz. IN-1048, Clemson spineless, Punjab selection, 1936 and IN-97 as parents under wastewater condition. The experimental lay out consisted of in CRD in full diallel cross mating in the research area of the Department of ...

in order to investigation of nitrogen fertilizer split application effect on quantity yield and grain quality of rice varieties, an experiment was carried out based on rcbd design as split plot experiment in three replications in langroud in 2006. mainand sub factor were variety (hashemi and bahar 1) and five nitrogen fertilizer split application (split of 150 kg.ha-1 n at transplanting, stemmi...

To evaluate superior hybrid combinations, biometric techniques based on the quantification of heterosis as in the diallel analyses and predictive procedures are commonly being used. Diallel analyses have the disadvantage of requiring the evaluation of each parent in all possible combinations, which may be impossible in the case of studies involving many parents. The predictive methods which dis...
