In traditional mixed cropping of arid region, cowpea (Vigna unguiculata) is grown for grain production butits pre-mature pods are also used for vegetable culinary. The indigenous germplasm of vegetable and multi-purpose pod-use was initially collected from arid, semi-arid and tribal areas of Rajasthan and Gujarat during2001 and 2002 as regional diversity. The potential germplasm were used in breeding for purification over theyears and 10 genotypes were maintained at CIAH. During rainy season of 2018, 28 diverse cowpea germplasmfrom wide geographical regions covering state of Rajasthan, Gujarat, Karnataka, Kerala and Uttar Pradeshwere studied to quantify component of genetic variability and performance under hot arid agro-climate at CIAH,Bikaner. The germplasm were characterized for plant growth, maturity, pod quality and yield component andgood amount of variations were recorded for characters such as plant height (41.6-207.3 cm), days to firstharvest of tender pods (37-66 DAS), pod length (10.9-29.7 cm) and weight (2.2-7.3 g) at vegetable use stages.The line AHCP-1-4-1 and AHCP-2-3 were studied for their performance in comparison to popular varieties(RCV-7, Arka Garima, Kashi Nidhi and Kashi Kanchan). The AHCP-1-4-1 is purified line producing vegetabletype pod quality and is from germplasm collected from local market (Haart) of village Limkheda and Jhalod of district Daahod (Gujarat). The purified line AHCP—2-3 is multi-propose type, locally known as bindodi-chawalaand is trait specific for rainfed arid farming. It is very early in tender pods harvesting (47 DAS), high yielding anddrought tolerating. |
