Genetic and environmental variability in some agronomical and botanical characters of common vetch (Vicia sativa L.)

Twenty-four lines of common spring vetch (Vicia sativa L.), extracted at random from a collection of about 180 lines, were tested for four years at one location. Data on vegetative, reproductive and forage quality characters were recorded and analysed for three years. Appreciable total genetic variability was found in most vegetative and reproductive characters, and only very little in forage quality characters. Compared with lotal genetic variability, large environmental variability was observed in most vegetative and forage quality traits. Reproductive characters, in general, were less influenced in this respect.
