Abstract:
Reali/ing the difficulty in determining the time of optimum maturity in groundnut, a
maturity index was formulated. Recombination breeding with high productive and extra early
types was undertaken. Combining ability was estimated by the line \ tester method. Among lines,
Chico was the best combiner for earliness. Among testers, TMV 2 was the best for productivity.
High yielding extra early recombinants were selected from the ?2 populations for further testing
and selection.
