Moench)” was conducted to estimate the genetic variability, heritability, genetic advance and correlation between seed quality parameters and yield. The experiment was conducted during kharif season of 2020 using Randomized Block Design with three replications. Observations were recorded for each genotype on seventeen different characters namely days to 50% flowering, plant height (cm), number of leaves, panicle length (cm), seed hardness (kg/cm2), threshed grain mold rating (%), specific gravity of seed (g/ml), germination percentage of seed, electrical conductivity (dsm-1), 1000 seed weight (g), shoot length (cm), root length (cm), root shoot ratio, vigour index length, vigour index mass, fodder yield per plant (g) and grain yield per plant (g). The ANOVA revealed highly significant difference among the all genotypes for all the characters studied indicating the presence of substantial amount of genetic variability. The GCV, PCV, heritability and EGA were estimated for all the characters. The characters electrical conductivity and thresh grain mold rating showed high GCV and PCV values. Highest heritability estimate in broad sense was observed for the character electrical conductivity. The highest value of expected genetic advance over mean was recorded for the character electrical conductivity. For the development of high yielding hybrids in sorghum, panicle length should be considered during selection. Due weightage should be given to plant height and number of leaves in developing high fodder yielding hybrids in sorghum. Similarly seed hardness should be taken in to consideration for improvement in the germination percentage of seed. For grain yield per plant, the fourteen hybrids viz., AKMS-90-A x STR- 293 x 426-2, AKMS-733-A x IVT-4121, AKMS-30-A X ICSR-91016, AKMS-30-A x Indore-26, AKMS-751-A x IVT-4121, AKMS-751 x IVT-17-4013, AKMS-751-A X SPV 1616 x 89028-3, AKMS-733-A x IVT-17-4013, AKMS-90-A X IVT-4121, AKMS-733-A X ICSR-1048-Sel.-2, AKMS-751-A x IVT-3004-1, AKMS-30-A X STR-293 x 426-2, AKMS-733-A x ICSR-8086-7-49 and AKMS-90-A x ICSR-1048-Sel.2 were significantly superior over the national check hybrid CSH-35 along with substantial percentage increase over the check. These fourteen hybrids hold promise in developing high grain yielding hybrids. For development of dual purpose hybrids, five hybrids i.e. AKMS-751-A x IVT-4121, AKMS-30-A x Indore-26, AKMS-30-A x ICSR-9106, AKMS-751-A x IVT-17-4013 and AKMS-90-A x STR-293 x 426-2 appeared best because of their good grain yield along with good fodder yield as compared to the national check hybrid CSH-35.EnglishThesis
