Genetic variability, heritability and genetic advance in aromatic lines of rice (Oryza sativa L.)

Author(s):

KK Barhate, MS Jadhav and VV Bhavsar

Abstract:
The forty five aromatic rice genotypes were used to study Genetic variability, heritability and genetic advance .The highest estimates of GCV and PCV was recorded for L:B ratio, 1000 grain weight and grain yield per plant. Moderate estimates of PCV and GCV values were recorded panicle length, number of tillers per sq.m., number of grains per panicle, straw yield per plant and harvest index. Almost all the characters showed high percentage of heritability. It indicate that character is least influenced by the environmental effect, suggesting scope for improvement of respective characters. The characters number of tillers per square meter, straw yield per plant, grain yield per plant showed high heritability accompanied with high genetic advance, it indicate that selection is effective for this character.
