    Genetic divergence analysis in indian mustard (brassica juncea (l.)czern & coss) germplasm
    (CCSHAU, 2006) Goyat, Binesh; Dhiraj Singh
    Two hundred germplasm lines were evaluated for genetic divergence. The experiment was laid in augmented design. The highest intra cluster D2 values was observed for cluster 3, with euclidean distance (4.23). The inter cluster distance have been found to be highest between cluster 1 and 6 euclidean distance (5.546). The cluster mean values were observed maximum in cluster 6 for no. of primary branches per plant, main shoot length, no. of siliqua on main shoot and oil content. Genotypic and phenotypic variances and coefficient of variation revealed substantial genetic diversity in the material. High heritability was observed for no. of seeds per siliqua and main shoot length. Genetic advance as per cent means were high for seed yield, no. of primary branches and no. of secondary branches per plant. Seed yield per plant showed positive significant correlation for no. of primary branches, no. of secondary branches, siliqua on main shoot. No. of secondary branches showed maximum positive direct effect for seed yield. Promising germplasm lines based upon different quantitative characters where identified. The use of such identified lines is advocated for developing superior genotypes/hybrids.

    Study of combining ability and effects of CMS sources on the performance of hybrids in pearl millet (Pennisitum glaucum (L.) R. Br.)
    (CCSHAU, 2006) Vinay; Yadav, H.P
    The present investigation was carried out to study the effect of different sources of cytoplasm on the general and specific combining ability effects and correlation coefficient in pearl millet. The material for the present study consisted of fourteen male sterile lines representing five systems of male sterility viz three from A1 source and one each from A4, A5, AG and Aegp and their counter part as maintainer lines with six diverse testers. These 84 crosses along with two checks HHB67 and HC-20 were grown in randomized block design with three replications during kharif 2002-03. The observations were recorded on nine characters viz., grain yield (g/plant), dry fodder yield (g/plant), plant height (cm), ear girth (cm), effective tillers, leaf length (cm), ear length (cm), days to 50% flowering and leaf width (cm). -xvi- -15- The analysis of variance for the design of experiment revealed that significant genetic variability was present among crosses for almost all the characters studied. The estimates of general predictability ratio revealed that non-additive type of gene effects were higher in magnitude for grain yield and its component traits except leaf length in which additive gene effect was higher in magnitude. The estimates of general combining ability effects revealed that lines 81Aegp and 502AG representing Aegp and AG cytoplasmic systems combined better for grain yield and most of its contributing traits. Testers HTP94/54 and CSSC46-2 were top general combiners for grain yield and majority of the component traits except effective tillers. For effective tillers testers namely ISK-48 and H90/4-5 were good general combiners. The estimates of SCA effects revealed that the hybrids 81A5 x HTP94/54, 502AG x 77/29-2, 81B5 x CSSC 46-2 and 502BG x HTP 94/54 were identified as desirable crosses for grain yield and majority of its component traits. Dry fodder yield showed positive and significant correlation with days to 50 per cent flowering, ear length, ear girth and grain yield. Grain yield was significant and positively correlated with days to 50 percent flowering, effective tillers, ear length and dry fodder yield. Implications of these results have been discussed in the present study.
