Table 8 Estimate of parameters of variability, heritability, and genetic gain of some characters of the rice varieties in the M1 generation

From: Growth, yield, genetic parameters and random amplified polymorphic DNA (RAPD) of five rice varieties treated with sodium azide and sown under different saline conditions
