Determination of yield and quality characteristics of some grasspea (Lathyrus sativus L.) genotypes in Isparta conditions

The research was carried out in Isparta ecological conditions in order to determine and examine the seed yield and quality characteristics of some grasspea genotypes in the 2020-2021 growing season. In the research, 120 grasspea genotypes and four cultivars (Corea, Iptaş, Gürbüz and Karadağ) were used as plant material. The experiment was carried out according to the augmented trial design. In the study, plant height, number of main stems, the number of pods per plant, pod length, pod width, the number of seeds per pod, 1000 seed weight, biological yield, seed yield, harvest index, protein ratio, acid detergent fiber (ADF) and neutral detergent fiber (NDF) were determined. In terms of all parameters examined in the study, statistically significant differences were determined between genotypes. According to the research results; the plant height of genotypes is 14.48-76.80 cm, number of main stems between 1.00-9.00, number of pods per plant 2.81-62.00, pod length 2.10-4.10 cm, pod width 0.71-1.40 cm, number of seeds per pod 1.23-4.32, 1000 seed weight 41.69-238.00 g, biological yield 3.06-82.40 g/plant, seed yield varied between 0.34-33.00 g/plant. harvest index between 3.07-55.27%, protein ratios is 13.52-24.64%, ADF 7.19-10.22%, NDF 11.52-24.23% According to the results of the research, it was determined that the genotypes "GP40, GP18, GP161, GP145" in terms of yield, "GP242, GP234, GP207, GP209, GP213 and GP226" in terms of quality were superior to other genotypes in the climate and soil conditions of Isparta province. It was concluded t
