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.
