Abstract
ICSV 88032, a high-yielding sorghum line highly resistant to S. sorghicola, was developed in India by pedigree breeding from a cross between ICSV 197 (midge-resistant line) and ICSV 1 (a high-yielding sorghum cultivar). In the international sorghum variety and hybrid adaptation trial, ICSV 88032 recorded yields of 4.8-5.2 t/ha during 1990-91, compared to 5.0-5.3 t/ha for ICSV 112, a released commercial cultivar, at Bhavanisagar (Tamil Nadu) and Patancheru (Andhra Pradesh). At Surat, ICSV 88032 had grain yields of 2.6 and 4.6 t/ha (2.9 and 3.4 t/ha for ICSV 112) during 1990 and 1991, respectively. In the preliminary variety trials of AICSIP in 1990-91, ICSV 88032 and ICSV 112 had grain yields of 3.1 and 2.8 t/ha, respectively. In the 1991 and 1992 advance variety trials of AICSIP, grain yields reached 4.0 and 3.6 in ICSV 88032, and 4.2 and 3.1 in ICSV 112, respectively. Damage by S. sorghicola was lower on ICSV 88032 (12-14%) than on the resistant control DJ 6514 (18-20%) and susceptible control CSH 1 (90-94%). Visual damage ratings varied from 2.1 to 3.4 in ICSV 88032, compared to 1.3-1.8 in DJ 6514 and 8.4-9.0 in CSH 1. The resistance of ICSV 88032 to S. sorghicola has been confirmed across locations in India, Latin America and West Africa. In 1995-96, damage by S. sorghicola reached 16-31% in ICSV 88032, 9-26% in ICSV 197 (resistant control), and 38-83% in Swarna (susceptible control). The loose panicle of ICSV 88032 makes it less susceptible to head bugs and earhead caterpillars. ICSV 88032 was as susceptible to shoot fly [Atherigona soccata] and stem borer as ICSV 112 and CSH 5.
