Genetic variability for seed cotton yield and itscomponents were studied in three segregating F2 populations of (Gossypium hirsutumL.). Significant variation was recorded major traits all the populations. Traits such as plant height (20 cm to 143 cm), bolls per (1 30), boll weight (2.0 g 6.8 g) (1.8 115 exhibited wide range.High PCV GCV estimates under study except days 50 cent flowering openin...

in order to estimate heritability and gene action for grain yield and its related traits in lentil, six basic generations were evaluated in a randomized complete block design with three replications in a field experiment. besides seed yield per plant, plant height, pod length, and 100-seed weight, the number of pods per plant, primary branches, clusters per plant, nodes per main stem, secondary...

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....

Pathogen traits, such as the virulence and the transmissibility of an infection, can vary significantly between patients. A major challenge is to measure the extent to which the genetic differences between infecting strains explain the observed variation of the trait. This is quantified by the so-called broad-sense heritability ! ! H 2 – a term borrowed from quantitative genetics of sexual spec...

Studies using the classical twin design often conclude that most genetic variation underlying personality is additive in nature. However, studies analyzing only twins are very limited in their ability to detect non-additive genetic variation and are unable to detect sources of variation unique to twins, which can mask non-additive genetic variation. The current study assessed 9672 MZ and DZ twi...

Basic intellectual abilities of quantity and numerosity estimation have been detected across animal species. Such abilities are referred to as 'number sense'. For human species, individual differences in number sense are detectable early in life, persist in later development, and relate to general intelligence. The origins of these individual differences are unknown. To address this question, w...

Ninety-two rice (Oryza sativa L.) genotypes were evaluated during kharif 2013 to estimate the genetic variability, heritability and correlation coefficients for 14 physicochemical and cooking quality traits. The experiment was conducted in a complete randomized block design with 3 replications. Highly significant (P < 0.01) differences were observed for all 14 quality characters studied. Among ...
