Abstract
A present investigation entitled “Assessment of seed quality, growth parameters and yield in kharif sorghum (Sorghum bicolor (L.) Moench)” was conducted to estimate the genetic variability, heritability, genetic advance and correlation between seed quality, growth parameters and yield. The experiment was conducted during kharif season of 2016 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 threshed grain mold rating and electrical conductivity showed high GCV and PCV values.
Highest heritability estimate in broad sense was observed for the character fodder yield per plant. The highest value of expected genetic advance over mean was recorded for the character threshed grain mold rating.
For the development of high yielding hybrids in sorghum, panicle length should be considered during selection. Due weitage 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 ten hybrids viz., AKMS 90 A x AKR 544, ICS 279 A x AKR 544, ICS 279 A x AKR 536, AKMS 90 A x AKR 325-1, AKMS 90 A x AKR 535, AKMS 30 A x AKR 492-1, ICS 89022 A x AKR 547, AKMS 30 A x AKR 527, AKMS 90 A x AKR 337 and AKMS 30 A x AKR 520 were significantly superior over the national check hybrid CSH-35 along with substantial percentage increase over the check. These ten hybrids hold promise in developing high grain yielding hybrids. For development of dual purpose hybrids, two hybrids i.e. AKMS 90 A x AKR 544 and AKMS 30 A x AKR 492-1 appeared best because of their good grain yield along with good fodder yield as compared to the national check hybrid CSH-35.
To develop single cut fodder hybrid, the cross ICS 89022 A x AKR 325-1 with highest fodder yield per plant of 199.93 g need to be exploited.
