A diallel cross from seven parents and their F1 hybrids were evaluated across three locations using a Randomized complete block design with replications for quantitative traits performance. Parameters assessed include plant heights, days to 50% headings, panicle lengths, weights, number of seeds per panicle, productive tillers, branches, yield plots which extrapolated in tonnes hectare 100 grai...

Dissection and chemical analysis data from 197 bulls of 15 breedtypes were used to examine the distribution of total fat (TOTFAT) among carcass fat (CFAT), viscera fat (VIF), kidney plus pelvic fat (KPF) and blood fat (BLF). The bulls were obtained from a five-breed diallel involving Angus, Brahman, Hereford, Holstein and Jersey; reciprocal crosses were pooled. One or two bulls of each breedtyp...

The results on optimal designs for diallel crosses are based on standard linear model assumptions where the general combining ability effects are taken as fixed. Recently Ghosh and Das (2003) proposed a random effects model that allows one to first estimate the variance components and then obtain the variances of these estimates. In this paper we first propose an unbiased estimate of the ratio ...

partial diallel design can be used to investigate the general and specific combining ability, and heterosis. combining ability and heterosis were studied in a 6×6 partial diallel cross to see the nature of gene action for fruit quality indices in cucumber (cucumis sativus l.) during 2007 to 2009. analysis of variance revealed highly significant differences among all the f1 hybrid means and thei...
