Abstract

The present investigation was carried out to study the combining ability for yield and yield related traits. Among the parents KH-111 found best general combiner for seed cotton yield per plant and component characters. Two hybrids, KH-111 x RAH-101 and NA-1325 x G. Cot-16 identified as best cross combinations based on sca effects for seed cotton yield per plant , yield contributing components and fibre quality parameters.

Keywords

General Combining Ability and Specific Combining Ability.

Abstract

Selected lines of safflower (Carthamus tinctorius L) were used to predict the heterosis for yield and yield components and to assess the reliability of prediction methods. The highest magnitude of useful heterosis was observed in respect of number of seeds per capitula (53.78%), seed yield per plant (27.23%), 100 seed weight (2.58%) and days to maturity (-2.87%). Only one cross, AKMS 1 x JLSF 228 recorded significant useful heterosis over the check variety Bhima for seed yield per plant (27.23%).The parents JLSF 228, A₁ and Bhima were good general combiners for seed yield per plant. The predictive model was effective for describing hybrid. There was, however, the positive relationship between mid parent and hybrid yield indicating that mid parent may still be a useful guide for the selection of parents for testing hybrid combinations. The effectiveness of predictive and postdiction model differed for different characters except for number of seeds per capitulum and days to maturity for which both models were equally effective in predicting hybrid yield.

Abstract

Top cross analysis consisted of crosses between GMS line AKSMS 1 as a tester (female) and twenty one male lines. Significant heterosis was observed for all the ten quantitative traits except number of capitula per plant and oil content. The magnitude of heterosis and useful heterosis was low and differed for different characters. The highest magnitude of useful heterosis was observed in respect of number of seeds per capitulum (53.78 %), seed yield per plant (27.23 %), 100 seed weight (2.58 %) and days to maturity (-2.87 %). Only one cross, AKSMS 1 X JLSF 228, recorded significant useful heterosis over check variety, Bhima for seed yield per plant (27.23 %). AKSMS 1 X JLSF 228 showed significant highest useful heterosis for number of seeds per capitulum (53.78 %). The estimates of general combining ability indicated that JLSF 288 recorded highest significant general combining ability effect for seed yield per plant (26.27**), plant height (10.41 **) and number of seeds per capitulum (9.87**). A 1 showed significant general combining ability effect for seed yield per plant (15.91**). Bhima was good general combiner for seed yield per plant (13.39**), plant height (6.16**), number of primary branches per plant (1.74**) and 100 seed weight (0.96**).

Abstract

The stability of 58 genotypes of American cotton comprising of 10 parents, their 45 hybrids produced in diallel fashion (without reciprocals) were evaluated in three environments for yield and its component characters. Significant E+(G x E) interactions showed differentional response of genotypes under different environments. Stability parameters revealed that the hybrids NH-452 x RAH-2211, DHY-286-1R x JK-276-10-5 and NA-1325 x RAH-101 found stable over the locations with high seed cotton yield, regression near unity and non significant deviation from regression.

Keywords

Abstract

Twelve genotypes of mungbean [Vigna radiata (L.) Wilczek] were evaluated for seven quantitative traits in three environments. Genotype x Environment interaction was found significant for all the traits. The major portion of G x E interaction was due to the linear component. Hence, the prediction of genotypic performance could be possible over environments. The genotypes TARM 18, PM 9377 and Vaibhav were found high yielding, responsive with non significant deviation mean square for most of the yield traits.

Abstract

The parents and crosses differed significantly for most of the characters indicating considerable amount of genetic variability in the materials studied. The lines MS 104B and SPSFR 94010B and the testers SFCR 125 and SFCR 151 were found as best general combiners. Amongst the crosses MS 104A x SFCR 151, SPSFR 94010A x SFCR 125 and PMS 7A x ICSV 700 were identified as best considering sca effects for shoot fly resistance traits and grain yield.
