Abstract
In the central semiarid region of the province of Córdoba, Argentina, there are not many fresh forage-producing annual legumes in the autumn-winter-spring period. The availability of species or cultivars of this family may allow the improvement of the soil nutrient level and of the quality of the cattle diet. One of the species that is known to produce fresh forage in good quantity and quality during this period with no irrigation is Vicia dasycarpa. With the aim of obtaining phenotypes adapted to the climatic conditions of the central region of Córdoba, a breeding program of a Vicia dasycarpa population R.P. N° 250 has been initiated using the adaptive response to the environmental conditions as the selection criterion. The selection characters were: tolerance to conditions of low precipitation and low temperature, growth vigor, cycle length, insect and disease resistance, and the weight of 1000 seeds. The constant selection of individual plants that showed a better genotype-environment adaptation determined a change in the genetic frequency of the selected characters in the phenotypes in relation to the original population. The results of this genetic advance are expressed in the new cultivar of Vicia dasycarpa named "Tolse F.C.A."
