Question

Genetic variability studies for yield and contributing traits under two plant density and molecular diversity analysis in maize (zea mays l)

Answer 1

1. Answer:
2. The experiment was conducted to study the genetic variability for yield and its contributing traits under two plant densities and molecular diversity analysis in ten inbred lines of maize. Both Genotypic coefficient of variation and Phenotypic coefficient of variation exhibited high value for number of kernel rows/ear and grain yield under both the optimum plant density and high plant density environments. Most of the traits studied showed high estimates of broad sense heritability and high expected genetic advance under both the environments, which indicated that most likely the heritability is due to additive gene effects and selection may be effective for these traits. The Polymorphic Information Content values of SSR markers ranged from 0.20 (Umc 1595) to 0.30 (Umc 2313) which indicated that SSR markers could be efficiently applied to detect genetic diversity on the basis of its polymorphic nature. The Jaccard's similarity coefficients between pairs of genotypes were found to vary from 0.50 to 0.84 and UPGMA divided the populations of ten inbred lines into four main groups. Thus, the inbred lines used in the present study have ample amount of variability (morphological and genetic) which can further be exploited to obtain maize variety/hybrid with enhanced yield potential.
