| dc.description.abstract | The investigation was undertaken during the period from 1993 to 1995 at Rahuri to study genetic diversity in two types of soil viz., light and medium soil in rabi season and combining ability and stability analysis in kharif season under light and medium soil and rabi season under light and medium soil in respect of eleven characters in sorghum. The D statistic showed that there was adequate 2 diversity among the genotypes with D values ranging from 11.40 to 2501.22 (light soil type condition) and from 13.79 to 2 2297.07 (medium soil type condition). On the basis of D values, 50 genotypes were grouped into 13 and 16 clusters under light and medium soil type conditions, respectively. Clustering pattern of these genotypes did not necessarily follow the geographical distribution. On the basis of inter cluster distance, cluster mean and p_e_r s_e performance IS-9318, IS-3578, SPV-1221, RSLG-17, RSLG—49, SPV-1209, SPV-1211 and RSLG-12 genotypes have been identified for hybridization programme under both light and medium soil type conditions, while the genotypes viz. , 15-9318:.-, IS-4993, IS-517, IS-3578, IS-5031, SPV-1221, RSLG-17, RSLG-49, SPV-1209, SPV-1211 and RSLG-12 for light soil and IS-9318, IS-3578, SPV-1209, Lokhandi, SPV-1211, RSLG-3, RSLG-12, RSLG-17, RSLG-43, RSLG 49, SPV-1221, SPV-1219 and RSLG-19 for medium soil have been identified for hybridization programme. The studies on combining ability indicated that there was considerable amount of genetic variability among the parents for all the characters under study. The male sterile lines 116A, 36642A, 117A and 42A and restorers SPV-475, SPV 938, SPV-462, SPV-1010, SPV-655, SPV-1090, Sel.3 and CSV-14R were found to be good general combiners for majority of the important characters. The crosses 116A x SPV-475, 116A x SPV 462, 36642A x SPV-1010, 36642A x SPV-946, 36642A X SPV- 475, 36642A X SPV- 1025, 42A x SPV-655, 42A x SPV-475, 42A x SPV 462 and 36542A x CSV-14R exhibited good sea effects for grain yield and most of its components. Additive gene action was found to be predominant for days for 50 per cent flowering, plant height and panicle length in medium soil during kharif season and days for maturity in light soil during rabi season. While, non-additive gene action was found to be predominant for flag leaf area, number of leaves per plant, panicle breadth, 1000-grain weight, grain yield per plant, panicle weight, fodder yield, plant height and panicle length in medium soil during kharif season and days for maturity in light soil during rabi season. | en_US |
