Identification of Stable Determinate Growth Genotypes in the RIL Population of Chickpea (Cicer arietinum L.)

Abstract

Chickpea is a cool-season annual legume crop with lion share in India, accounting for 65% of annual world production. Despite its domestic production, it is unable to meet the current requirement. To encounter this, the identification of superior genotypes with high yield stability is essential. The present study was conducted in two locations to identify determinate type chickpea genotypes with high stable yield. Combined analysis of variance revealed significant genotype × environment interaction. Results of stability analysis identified the recombinant inbred lines viz., 183 (L1- 4866.66 kg/ha, L2- 1825 kg/ha), 12 (L1- 4416.66 kg/ha, L2-2325 kg/ha), 173 (Determinate type) (L1- 3466.66 kg/ha, L2- 2050 kg/ha), 165 (Determinate type) (L1- 3433.33 kg/ha, L2- 2030 kg/ha), 92 (Determinate type) (L1- 2708.33 kg/ha, L2- 1733.33 kg/ha) and 77 (L1- 4096.66 kg/ha, L2- 2051.66 kg/ha), exhibited superior performance at both the locations compared to the checks. Identified stable, superior genotypes in this investigation, could be further utilized for enhancing production and productivity eventually achieving the needed demand and food security in chickpea.
