performance of some grain sorghum lines and their hybrids under optimum and low input nitrogen conditions [electronic resource].

Includes reference.

Twenty-eight crosses were developed from four cytoplasmic male sterile lines (CMS-lines) and seven restorer lines (R lines) at Shandaweel Agric., Res., Station, Sohag, Egypt, in 2003 season. Twe field trails were conducted separately for each N level (First trail with 50 kg N/fed., Second trail with 100 kg., N/fed.,) in each trail, twenty eight crosses and their parental lines with the check Shandaweel-6 (sh6) were evaluated in 2004 and 2005 successive seasons in the same Station. Data were recorded on days to 50% flowering, plant height (em.), number of green leaves after grain filling, 1000grain weight (g.), grain yield/plant (g.) and Nitrogen Tolerance Index (NTI).
