RELATIVE EFFICIENCY OF DIFFERENT METHODS OF GENERATING VARIABILITY IN TRITICUM DURUM

Abstract

Comparison among randomly selected F3 progenies, F% biparental progenies and F4M% progenies was made to understand the impact on generating variability for yield, harvest index and another traits in durum wheat. It was observed that biparental mating in F% generation is able to provide greater variability for selection of plants of high yielding efficiency with high harvest index. Correlation studies also exhibited that biparental mating had generated strong character associations with grain yield. Improvement in increasing thenumberof tillers perplantwasfound to be difficult. Increase in harvest index and yield per plant in this study might be due to the elevation in mean of other component traits as a result of accumulation of desirable genes through biparental mating. Mutation breeding offered little chances to generate desirable variability for yield.
