Genetic advance for yield traits

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.

The material for the present study consisted of 30 F4 families of bhendi, to assess the genetic components for growth and yield at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, UT of Puducherry, India. The mean values and ranges recorded for various traits under study revealed significant variation. The maximum range of variability was observed for fruit yield plant-1 (148.0 to 377.31 g), followed by plant height at final harvest (76.56 to 160.40 cm).

Genetic variability, heritability and genetic advance were studied in 22 germplasms of Dolichos beans for yield attributing traits. Analysis of variance revealed significant differences among the genotypes for all the characters studied. For all the characters studied, phenotypic coefficients of variability were higher in magnitude than genotypic coefficients of variability, though difference was very less in majority of the cases.

The experiment was conducted during 2015-2016 at Division of Plant Genetic Resources, Indian Institute of Horticultural Research (IIHR), Hessarghatta, Bengaluru. Genotypic variability, heritability and genetic advance for yield and yield contributing traits were studied on 13 Holostemma ada-kodien accessions. Data were recorded on plant height (m), leaf length (cm), leaf width (cm), petiole length (cm), pedicel length (cm), fruit length (cm), fruit diameter (cm), thickness of pericarp (cm), thickness of mesocarp (cm), number of fruits per plant, fruit yield (kg).

At the same time, the breeding lines from the advanced generations are also used as parental lines for developing commercially exploitable heterotic hybrids. But, most often the source of early generations i.e., F3, F4, F5 and F6 segregating populations offer wider opportunities for achieving high success, because of wider genetic base.

Thirty mungbean genotypes were evaluated for the estimation of genetic variability, heritability, genetic advance, correlation coefficient, and path coefficient analysis for yield and its component traits. A considerable amount of genetic variability was observed among all the genotypes for all the characters under study. GCV & PCV were highest for seed yield per plant, followed by harvest index, biological yield and number of pods per plant.

Twenty one accessions of okra were assessed for variability for 12 characters. Highly significant differences were observed among the accessions. High phenotypic and genotypic coefficient of variation was observed for per cent incidence of YVMV, yield per plant, fruit weight, and number of fruits per plant indicating the existence of wider genetic variability for these traits in the germplasm.

Thirty seven rice genotypes were evaluated for their variability with regards to yield and yield components. Estimates of heritability and genetic advance in percent of mean were also obtained for the above traits. All the characters under study except days to fifty percent flowering exhibited high heritability coupled with high genetic advance as per cent of mean, which indicated that these traits were controlled by additive type of gene action in the inheritance of these characters.
