IAC 2051: common bean cultivar of carioca type with slow seed coat darkening

IAC 2051 is a common bean (Phaseolus vulgaris L.) cultivar with carioca-type seed coat, mean 1000 seed weight of 300g, indeterminate semi-upright type II growth habit, slow post-harvest seed coat darkening, resistance to Fusarium wilt, common bacterial blight, and three races of anthracnose, and mean yield of 2729 kg ha^-1.

Keywords:
Phaseolus vulgaris L.; plant breeding; disease resistance.
