Additional Information



These 3 new Cicer arietinum cultivars were selected for their ability to flower and set pods at temperatures which are low enough to restrict growth of conventional cultivars. They were derived from the crosses Gaurav × (G130 × (ICC893 × Chafa)) (ICCV88506 and ICCV88510) and Pant G114 × (G130 × (ICC8923)) (ICCV88503), where ICC893 is of Russian (K1189) origin, G130 and Chafa are brown-seeded (desi) Indian cultivars, and Gaurav and Pant G114 are high-yielding cultivars adapted to Hisar, northern India. In trials at Hisar during 1988-89 and 1989-90, ICCV88503 and ICCV88506 showed greater cold tolerance by flowering 30-40 days earlier than the controls Gaurav and Pant G114 and setting pods at 21.2±0.7°C (day time) and 5.9±0.5°C (night time). ICCV88510 flowered 4-10 days earlier than the controls and set pods at 22.9±0.6°C and 6.8±2.6°C. In national trials, ICCV88510 yielded 1.1 and 2.7 t/ha (16 and 24% more than Pant G114) when sown in October-November (normal time) and December (late sowing), respectively. This cultivar was also resistance to wilt caused by Fusarium oxysporum f.sp. ciceri. The new cultivars had 7-10% higher harvest indices (41-42% vs. 33-35%), larger brown seeds and were taller than the controls.
