ABSTRACT- Barley (Hordeumvulgare L.) is one of the most important cereals in the world which is used as human and cattle feed and for malt production. One of the most important steps in a hybrid and selection breeding program of barley is the selection of suitable parents with high general (GCA) and specific combining ability (SCA) for grain yield. In order to estimate the combining ability and...

in order to study the gene actions and heritability of the physical and chemical characteristics associated with appearance and cooking quality of rice grain, generation mean analysis was performed using a cross between two iranian rice cultivars, deylamani and sepidroud, having different quality characters. seeds of the parental lines and f1, f2, bc1 and bc2 generations were grown in randomize...

Evaluation of eggplant (Solanum melongena) genotypes, including one control check and nine mutants for ten agronomical characters to assess the magnitude of variability and to pick up the heritable component of variation present in the agronomic traits, revealed significant differences among the genotypes for all the studied characters indicating the presence of substantial genetic variability....

due to cereal are affected by drought stress in their lifetime. in order to study gene action of bread wheat under drought stress condition, a generation mean analysis was performed using f1, f2 and f3 generations derived from roushan and kavir. generation mean analysis was performed based on joint scaling test. genetic parameters including additive effect (d), dominance effect (h), additive×ad...

Advanced button mushroom cultivars that are less sensitive to mechanical bruising are required by the mushroom industry, where automated harvesting still cannot be used for the fresh mushroom market. The genetic variation in bruising sensitivity (BS) of Agaricus bisporus was studied through an incomplete set of diallel crosses to get insight in the heritability of BS and the combining ability o...

Litter size is an important reproductive trait as it makes a major contribution to fitness. Generally, traits closely related to fitness show low heritability perhaps because of the corrosive effects of directional natural selection on the additive genetic variance. Nonetheless, low heritability does not imply, necessarily, a complete absence of genetic variation because genetic interactions (e...

Fifty genotypes of CIMMYT bread wheat were evaluated at Agricultural Research Farm, BHU, Varanasi during 2019-2020.The analysis variance revealed significant differences among for all traits. High Phenotypic coefficient variation was recorded compared to the genotypic variation. However, high coefficients found particularly for: grain yield per plot (8.71), harvest index (9.22), test weight (8....
