Genetic advance for yield

The objectives of this study were to identify promising rice genotypes and evaluate the genetic variance and effectiveness of selection of the rice varieties for several yield attributing traits. A varietal trial of fifteen rice genotypes was laid out in a randomized complete block design (RCBD) with three replications in a farmer’s field in Sundarbazar, Lamjung, Nepal during the rainy season of 2018.

Twenty one genotypes including check Krishna were evaluated in randomized block design with three replications during kharif-2017 at research farm of TCA, Dholi for estimation of genetic variability among them. Genotypes varied significantly for all the morpho-physiological characters indicating the presence of considerable variability among the genotypes. Significant bidirectional shift was observed in the mean values as compared to better check, thus provided scope for selection.

The present investigation was under taken with the objectives to estimate genetic variability, heritability and genetic advance for yield and yield contributing components of cucumber. The experimental materials for this investigation were fourteen genotypes of cucumber consisting of parthenocarpic, gynoecious and monecious germplasms crossed in line × tester mating design produced thirty three hybrids (F1). Thirty three F1 crosses along with their parents were evaluated in two environments viz.

The present investigation was carried out to estimate phenotypic and genotypic coefficient of variation, heritability (broad sense), genetic advance and genetic gain for 15 quantitative traits in 21 different genotypes of Garden pea during Rabi2011-12 at Vegetable Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (U. P.). Significant differences among the genotypes were observed for all the characters under study.

The present investigation for genetic variability was made based on the data recorded for sixteen yield and yield contributing quantitative and qualitative characters in twenty one rice genotypes using statistical tool.There are significant differences among the genotypes for all the characters under study showed by analysis of variance.

The experiment was conducted in experimental Farm, Regional Research Station, Anand Agricultural University from July to November 2018toestimate the extent of variability present in rice genotypes with respect to yield and its component traits. The estimates of genotypic and phenotypic variances for the characters like plant height, effective tillers per plant, number of grains per panicle, grain yield per plant, straw yield per plant, harvest index and 1000 grain weight, genotypic variance contributed larger in phenotypic variance.
