Evaluation of Trait-based and Empirical Selections for Drought Resistance at Udaipur,Rajasthan, India uri icon

abstract

  • The performance of 8 parental groundnut genotypes (ICGS 76, CSMG 84-1, ICGS-44, ICGV 86031, TAG 24, GG 2, JL 220 and K 134) and 192 progenies was evaluated in Udaipur, Rajasthan, India, during 2000 (rainy season). The top 20 genotypes for kernel yield were identified by trait-based (9) and empirical (11) selections. For these genotypes, a kernel yield of 3411-4662, harvest index (HI) of 0.39-0.47, transpiration efficiency (TE) of 2.01-2.16 g/kg, and transpiration level of 377-492 mm were recorded. JAL 17, JUG 11, ICR 39, ICR 23 ad JAL 24 showed a significant improvement (from 12.7 to 28.1%) in kernel yield over the parent with the highest yield (TAG 24, 3639 kg/ha). Relative to TAG 24, higher HI (by 0.4-3.2%), TE (by 1.2%) and T (by 10.5-27.66%) were observed in 4, 3 and 5 of these genotypes. JAL 17, ICR 39 and ICR 23 showed significant increases in all 3 traits over the control
