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

The field experiments with thirty genotypes were conducted during June to October month of kharif, 2018 and 2019, assess extent variability under aerobic condition. sown dry direct seeded condition using randomized block design (RBD) three replications. Each genotype was in single row 5 m length spacing 20 cm between rows 15 plants. Data recorded for 22 characters including different morphological quality traits from randomly selected plants each replication mean data used analysis. ANOVA revealed that the sum squares highly significant difference most traits. value PCV higher than GCV all twenty-two characters. However, maximum observed root weight plant-1 (31.44% 32.17%) followed grain yield (29.97% 31.03%), volume (28.62% 29.20%), fresh (28.51% 29.08%), biological (21.86% 22.50%) number grains panicle-1 (20.55% 21.37%). Rest showed moderate low PCV. High heritability genetic advance viz., leaf length, tillers plant-1, panicle-1, 1000 seed weight, volume, kernel length-breadth ratio, harvest index. information regarding will provide direction select high yielding
