to evaluate the effect of environment on the general and specific combining ability of virginia tobacco genotypes, five varieties were intercrossed in combination in 2007 in a half – diallel design. in 2008, the ten f1 population and the five parental lines were sown in two different conditions (drought stress and non-stress) using a complete randomized block design with three replications and ...

We estimated the genetic distances among 10 spring wheat genotypes based on pedigree data, morphological traits and AFLP markers, used individually and combined with morphological traits, to find the best predictors of general- and specific-combining abilities among parental genotypes. Ten wheat parents were crossed in a diallel form, disregarding reciprocal hybrids, totaling 45 combinations. T...

Data included pubertal, reproductive and lactation records of primiparous females produced in a diallel of Angus, Brahman, Hereford, Holstein and Jersey. Brahman heifers were oldest, tallest and heaviest at puberty, while Jersey heifers were youngest, shortest and lightest. Crossbred heifers were 22 d younger (P less than .01) at puberty than straightbred heifers; no significant differences wer...

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...

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...

The study was carried out to estimate magnitude of heterosis over better parent and standard check for some important characters in 15 crosses resulting from a half diallel mating design of 6 inbred lines of brinjal. Hybrid variety ‘Tarapuri’ was used as standard check. The parents and the hybrids were evaluated at the farm of Olericulture Division, HRC, BARI, during the winter season of 2008-2...
