A range of improved true-breeding lines with superior agronomic performance for early, concentrated maturity, resistance to three races of Fusarium wilt and excellent fruit appearance was developed using multiple sources from America. Several new experimental hybrids were developed from these lines and one was selected for immediate release. Statistical analysis of field trials indicated that while marketable yields for the best of the new hybrids was similar to the best current commercial hybrid, the former produced a significant 3% improvement in the proportion of marketable fruit.
