COMBINING ABILITY STUDIES FOR YIELD AND ITS COMPONENTS IN GROUNDNUT

Published on

Nine lines were mated to three testers in a line x tester design. Among the lines, ICGV-86125
proved to be a good general combiner for pod and kernel yield and unit pod weight.
Majority of the best specific combinations for different characters resulted from the crosses
among the parents with high x low or low x low gca effects. Non-additive effl!cts Wl!re
predominant for pod and kernelyield and shellingoutturn,butappreciable additivl! effects
were noted for pod number, pod weight, and primary branches. The breeding method
which can exploit both nonadditive as well as additive types of genl! action is suggested
for groundnut improvement.
