The experimental material included 21 F1 hybrids (developed by half diallel fashion), 7 parents and standard check were all planted in randomized complete block design with three replications at Bihar Agriculture University, Sabour. Among the Pusa Rohini, Arka Vikash S. pimpinellifolium whereas, among crosses, Rohini × Vikash, H-86 showed highly resistant for per cent disease incidence coeffici...

Parentage studies often estimate the number of parents contributing to half-sib progeny arrays by counting the number of alleles attributed to unshared parents. This approach is compromised when an offspring has the same heterozygous genotype as the shared parent, for then the contribution of the unshared parent cannot be unambiguously deduced. To determine how often such cases occur, formulae ...

In any breeding program, the creation of high-yielding maize hybrids with best possible heterosis expression depends on genetic diversity parental inbred lines. This study aimed to quantify eight lines using morphological features and determine relationship between in grain yield per hectare distance matrices variables. The principal component analysis (PCA) determined among based 22 assessed t...

LTHOUGH it is a matter of importance both theoretically and practically, A little is known about the constancy under different environmental conditions of the genetic components of continuous variation. This is not surprising, for study of the effects of environment upon the various genetic parameters required to specify continuous variation could not proceed until the parameters themselves wer...
