Seven castor accessions were subjected to diallel crossing without reciprocal in 2008. The seven parents and their 21F1 hybrids were evaluated in Makurdi and Yandev both in Nigeria in 2009 in a Randomized Complete Block Design (RCBD) replicated 3 times to obtain data on seedling vigour, yield and yield related traits in the crop seedling emergence data which were recorded on the whole plot at two-day intervals and used to compute emergence percentage (E%), emergence index (EI) and emergence rate index (ERI). Data on days to flowering, days to maturity, plant height, number of branches per plant, number of panicles per plant, 100-seed weight and seed yield per hectare on the middle row of each plot. Coefficient of linear correlation were computed for each pair of traits for the seven parents (accessions) and their 1 hybrids separately and the combination of parents and hybrids. Different patterns of correlation were observed among traits of castor accessions, the hybrids and the parents and hybrids combined. |
