Abstract

ICSA88019 and ICSB88019 (PI592505) and ICSA88020 and ICSB88020 (PI592506) are sorghum midge (Contarinia sorghicola (Stenodiplosis sorghicola))-resistant sorghum (Sorghum bicolor) seed parents based on the A1 CMS system and developed by ICRISAT at Patancheru, India. ICSB88019 and ICSB88202 were both derived by pedigree selection, and have the pedigrees IS152 × DJ6214-8-1-1-1-1 and FLR101 × DJ6514-13-1-1-2-1, respectively, where DJ6514 is a stable source of resistance to sorghum midge from India, IS152 is a locally adapted germplasm accession from India and FLR101 is an elite line derived from the FLR population. The B-lines were crossed to 296A (A1 cytoplasm) for conversion into male-sterile lines. Information is tabulated on plant height, time to 50% anthesis, grain yield and midge damage of the B-lines grown at Patancheru during the rainy season of 1991 and the post-rainy season of 1991-92
