A research on determination of yield and some yield components of forage pea (Pisum arvense L.) cultivars and lines in Diyarbakır ecological conditions

This study was carried out to determine yield and yield components of 18 genotypes of forage pea cultivars/lines under the arid land conditions of Southeastern Anatolia. The experiment was arranged in randomized blocks design with three replications in the cultivation year of 2006-2007. Some significant botanical and agricultural characteristics have been established at the raised lines. According to the data obtained from this study; green herbage yield changed from between 884.58?648 kg/da, dry herbage yield 189.59?332.72 kg/da, seed yield 71.66 - 246.33 kg/da. There has been highly significant and positive correlations between dry herbage yield and green herbage yield, similarly, there has been correlations between dry herbage yield and plant height, also, there has been significant and positive correlations between biological yield and seed yield. On the other hand, there has been significant but negative correlations between 1000 seed weight and number of pod per plant. According to the research results, the forage pea lines of P.51, P00.1.4.9.661 lines and Gezi ecotip can be recommended for green herbage and dry herbage, however, the lines of P00.1.4.9.661, P104 and P.101 can be used for seed production under Diyarbakır conditions.
