Genetic studies in F4 progenies
-
The present study was conducted to assess variability paramters for ten quantitative characters including seed yield per plant in mung bean utilizing thirty progenies of F4 population derived from two crosses viz., Meha x GJM-1006 (17 progenies) and Meha x GJM-1008 (13 progenies). Randomized Block Design with three replications was used and each genotype was planted on a spacing of 60 cm x 15 cm.

Progenies from a cross between ‘Gopaldoddiga’ and ‘ARB6’ cultivars were selected on the basis of combining ability analysis to study the genetics of transgressive segregation for zinc content and agronomic traits using augmented designs. Results revealed the presence of general combining ability and specific combining ability effects, and the parents were found to be good general combiners for zinc in grains, 100 grains weight and grain yield per plant.

In this research fifty F4 progenies of brinjal were subjected to study the extent of variability present in the experimental material. Analysis of variance indicated presence of large variability for different characters under study. Most of the growth, flowering, fruit and yield characters under study were found significantly varied. The magnitude of phenotypic variance was greater than genotypic variance in all the characters under the study.

Genetic variability is prerequisite for any crop improvement program as it helps breeders in selecting the superior plants in segregating generations. Genetic variability for yield and its contributing traits in F3 and F4 generations derived from the cross WH 711 / WH 542 was assessed. The 238 F3 and F4 progenies along with parents were characterized on the basis of 12 morpho-physiological traits. The study revealed highly significant difference among the progenies for yield and its contributing traits.
