Abstract
The study was conducted at the Faculty of Agriculture in Dicle University, Southeast Anatolia, Türkiye, during the 2023 growing season to estimate heterosis, heterobeltiosis, and dominance for phenological, leaf, and plant traits in F₁ hybrids from desi × kabuli and kabuli × kabuli chickpea crosses. In 2022, 2 desi (Black, ICCV 10) and 3 kabuli (Azkan, ILC 533, ILC 482) chickpea varieties were crossed, producing 10 hybrids and 5 parents evaluated in a randomized complete block design with 3 replications. Significant variation was found among genotypes for all traits. Days to first flowering ranged from 55.7 to 69.0 d, with Azkan having late flowering. Kabuli parents also generally showed larger plant and leaflet size than desi types. Negative heterosis for early flowering was observed in 4 hybrids, with Black × Azkan showing the highest negative heterobeltiosis (−17.39%). Over-dominance (dominance estimates [DE] = 1.61 to 5.79) was detected for days to first flowering. For plant height, Black × Azkan showed the strongest negative heterosis (−20.64%) and heterobeltiosis (−28.78%). Leaflet traits varied widely, with positive heterosis for number of leaflets per leaf (2.02% to 68.70%) in 5 hybrids. Promising chickpea hybrids were obtained for early flowering, short plant height, and large leaf size, which may inform breeding programs aimed at enhancing chickpea yield potential and adaptability.
