Identification of Large-Seeded High-Yielding Stable Kabuli Chickpea Germplasm Lines for Use in Crop Improvement uri icon

abstract

  • Seed size is an important trait in kabuli chickpea(Cicer arietinum L.). The kabuli chickpeas with a100-seed weight of >40 g garner higher marketprice as they are preferred by consumers. Theobjective of this study was to evaluate a sampleof chickpea landraces, breeding lines, andcultivars for morphological traits and yield andidentify lines that are high yielding and exhibitstable performance across environments. Weevaluated 65 large-seeded kabuli lines identified from the ICRISAT germplasm collection inthree sets, 18 trials, and 13 environments for 22qualitative and quantitative traits. Several highlysignifi cant correlations were observed in allthree sets and a few large-seeded high-yieldinglines with stable yield were selected. Two extralarge-seeded (100-seed weight > 50 g) lines ICC17109 (Blanco Sinaloa 92), a breeding line, andICC 17452 (CuGa 288), a landrace, both originatingfrom Mexico showed high yield potential andwere moderately stable across environments.The small-seeded control cultivars, though highyielding, were highly unstable, performing betteronly in favorable environments. The studyhas also shown that some vegetative characteristicswere more sensitive to stress than yieldand yield components, hence selection in unfavorableenvironments should be based on grainyield and its components
