superior to that of farmers’ selections (3.4 t ha -1 ). However, for other traits (grain size, days to 50% flowering, and
plant height) farmers’ selections were similar to that of breeders’ selections (grain size: 2.3 g 100 -1 , plant height:
1.9m, and days to 50% flowering: 77 days). Breeders’ selections were more tolerant to lodging (Table 2). From
these results, it can be concluded that though farmers selections in the early generations had bolder grains (2005
archival report), with advancement in generations, breeders’ selections had high grain yield with grain size similar to
farmers’ selections.

The advanced lines will be evaluated for shoot fly resistance. In another experiment, a total of 60 entries (selected
based on their yield and large grain), including checks, were planted in RCBD with 3 replications for evaluation for
grain yield and other agronomic traits during the post-rainy season 2006. The promising lines will be evaluated for
shoot fly resistance in 2007.

Milestone: Ten high yielding grain mold tolerant sorghum lines developed for rainy season adaptation (BVSR/RS)
2010
New sources of resistance for grain mold will be obtained and selfed during 2006/07 post-rainy season. Crossing
program will be initiated during 2007 rainy season using new sources of resistance to grain mold from germplasm
and high yielding adapted B lines.
