Response of sorghum genotypes to drought in Zimbabwe
1996
Mangombe, N. | Gono, L.T. | Mushonga, J.N.
The yield response of 20 sorghum genotypes to late-season drought at Chiredzi and Lucydale, over two seasons, 1992-93 and 1993-94 in Zimbabwe was studied. Under good rainfall at Chiredzi in 1992-93, NL 803, SV 1, NL 836-2, and NL 265 gave the highest yields. However, under late-season drought conditions in 1993-94, SV 1, NL 535, NL 699, and NL 692 gave the highest yields. At Lucydale, Chibonda, NL 265, NL 836-2, and SV 1 had the highest yields under adequate rainfall in 1992-93, but under late-season drought in 1993-94 season, SV 1, SV 2, NL 267, and NL 653 had the highest grain yields. Grain yield was positively correlated with plant height, exsertion of panicle, and 1000-seed mass, but not days to 50 per cent flowering
