MART-AZR Project Research Report 68: Selection of Vetch Genotypes under Rainfed Conditions in Highland Balochistan

Abstract

Feed deficits are a major limitation on animal productivity in the arid highlands of Balochistan and no adapted forage legume species are available locally for the cold and dry conditions experienced in these areas. An unconventional selection program to select and improve forage legumes species was the first step to overcome the feed deficits. This paper describes the results of evaluation and selection trials comparing Vicia sativa genotypes with Vicia villosa ssp. dasycarpa Acc 683 and with a local lentil species as an experimental control. The trials were conducted at multiple sites and seasons with winter and spring planting. V. dasycarpa was more productive both in total dry matter production and seed yield. In favourable environments V. sativa genotypes were equal in production to V. dasycarpa. V. sativa Acc. 713 has been selected for winter planting due to its better productivity across trial locations, yield stability under different environments and adequate level of winter hardiness. These newly selected forage legumes species have a high tolerance to the prevailing environmental stresses and if introduced, could have a positive impact on the dryland crop-livestock farming system in highland Balochistan.
