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
increasingthe numberof tillers perplantwasfound to be difficult. Increasein 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.
