Abstract

An experiment was conducted to determine the relationships among the F2 to F6 generations of 9 chickpea crosses (Cicer arietinum L.). The F2 yields had a significant and positive correlation with those of the F3. The mean yields of the F2 and F3 were not associated with the mean seed yield of the F4, F5 and F6. Significant associations among the F2 to F6 were found for days to 50% flowering, days to maturity and individual seed mass. From the results, it is concluded that selection based on early generation bulk yield tests may not be effective. The observed inconsistency in performance of different generations may have been caused by genetic shift and breaking of gene linkages
