Genetical and biometrical analysis for some important traits in maize

It is hoped that the present study may help maize breeders to produce new hybrid varieties having higher yielding potential. Molecular techniques are now a valuable tool for achieving advances in genome research and generating considerable interest in predicting hybrid performance. Molecular markers are of great value in genetic research and partially in breeding programs since they reflect the genetic variation among individuals. Various PCR-based marker techniques have recently been successfully introduced in the fingerprinting of plant genomes and in genetic diversity studies. Among them random amplified polymorphic DNA (RAPD) analysis which is relatively simple, rapid and cost effective. Diallel cross design is widely and extensively used for estimating the types of gene action. Several methods have been devised in this respect to estimate the genetic components in plant population, few information, however is available about comparing and relative efficiency of these methods.
