Purpose of Description

ICSV 692, ICSV 729, ICSV 730, ICSV 731, ICSV 736, ICSV 739, ICSV 744, ICSV 745, and ICSV 748 are midge-resistant sorghum lines developed at ICRISAT Center. These lines can be used in sorghum improvement programs in different countries, or adapted per se for cultivation by farmers in areas endemic to sorghum midge.

Origin and Development

These lines were derived by pedigree breeding. Midge-resistant lines DJ 6514, IS 2579 C, PM 7348, and ICSV 197 (PM 11344) were crossed with agronomically elite lines Diallel- 50-1-1 ALS, IS 3443, SPV 351, SPV 394, and A 6250. The segregating material has been selected for agronomic desirability and midge resistance under natural midge infestation and under no-choice headcage screening (Sharma et al. 1992). Their origins, pedigrees, and reactions to sorghum midge are given in Tables 1 and 2.
