Utilizing genetic diversity to select tomato lines tolerant of tomato yellow leaf curl virus based on genotypic coefficient of variation, heritability, genotypic correlation, and multivariate analyses [PDF]

Brazilian Journal of Botany, 2023
AbstractTomato yellow leaf curl virus (TYLCV) is one of the most destructive pathogens for tomato crops. The development of TYLCV-tolerant tomato lines (TLs) requires a thorough understanding of their genetic variability and relationships among lines and in traits of interest.

Estimation of Phenotypic Coefficients of Variation (PCV), Genotypic Coefficients of Variation (GCV), Heritability and Genetic Gain for Yield and its Components in Rice Landraces of Odisha

International Journal of Agriculture Environment and Biotechnology, 2019
The present investigation was carried out to study genetic variability in sixty-four low land rice genotypes (including fifty-five landraces of Odisha) for twelve traits. Analysis of variance (ANOVA) revealed significant differences among the genotypes for all the studied characteristics.

Study of Coefficient of Variation, Heritability and Genetic Advance for Different Traits of Rice Genotypes Grown under Aerobic Condition [PDF]

International Journal of Bio-resource and Stress Management, 2021
The field experiments with thirty genotypes were conducted during June to October month of kharif, 2018 and kharif, 2019, to assess extent of variability under aerobic condition. The genotypes were sown under dry direct seeded condition using randomized block design (RBD) with three replications. Each genotype was sown in single row of 5 m length with
