Parent Progeny regression analysis in F2 and F3 generations of rice

Abstract

Parent progeny regression analysis involving F₂ and F₃ generation of two crosses in rice was undertaken to estimate the genetic potential transferred from one generation to other by adopting three levels of selection for single plant yield. Significant positive correlation and regression was observed in both crosses at positive level of selection (mean +1SD) between F₃ mean and the corresponding F₂ values, indicating that selection of single plant yield at these levels would be effective in both crosses. It 
indicates the chances of selecting high yielding genotypes at early generations.
