Inter-specific hybridization is a key strategy in modern crop improvement, aiming to integrate desirable traits from wild species into cultivated backgrounds. This study delves into the evaluation and identification of advanced inter-specific derivatives (IDs) derived from crosses of cultivated chickpea with and . The primary aim was to incorporate desirable yield enhancement traits, disease resistance, and nutritional quality traits into cultivated chickpea. The IDs were assessed during 2021-22 and 2022-23 in the northern plains zone of India. Significant amount of genetic variability was observed for key agro-morphological traits having high heritability and genetic advance. Superior derivatives were identified for early flowering, high seed yield, and resistance to Ascochyta blight, Botrytis grey mould, and Fusarium wilt. Significant variability for crude protein and total soluble sugar content was also observed among the derivatives. The findings highlight the potential of utilizing wild species to broaden the genetic base of cultivated chickpea for the development of robust, high-yielding, disease-resistant varieties with improved nutritional traits suitable for diverse environmental conditions. The superior derivatives identified in this study hold promise for future breeding programmes for improving productivity, disease resistance and nutritional quality.
种间杂交是现代作物改良的一项关键策略,旨在将野生物种的优良性状整合到栽培品种中。本研究深入探讨了栽培鹰嘴豆与[具体物种1]和[具体物种2]杂交产生的高级种间衍生物(ID)的评估与鉴定。主要目标是将优良的增产性状、抗病性和营养品质性状融入栽培鹰嘴豆中。这些ID于2021 - 22年和2022 - 23年在印度北部平原地区进行了评估。在具有高遗传力和遗传进展的关键农艺形态性状上观察到了大量的遗传变异。鉴定出了在早花、高种子产量以及对褐斑病、灰霉病和枯萎病具有抗性方面表现优异的衍生物。在这些衍生物中还观察到粗蛋白和总可溶性糖含量的显著变异。研究结果凸显了利用野生[具体物种]拓宽栽培鹰嘴豆遗传基础的潜力,以培育出适应不同环境条件、具有改良营养性状的健壮、高产、抗病品种。本研究中鉴定出的优良衍生物为未来提高生产力、抗病性和营养品质的育种计划带来了希望。
