Determination of morphological and agronomical characteristics of grass pea (Lathyrus sativus L.) population and varieties in Yozgat ecology

This study was carried out in Yozgat ecological conditions in order to determine the morphological and agronomical properties of nine Grass pea (Lathyrus sativus L.) which four registered cultivars (İptaş, Eren, Karadağ and Gap Mavisi) and five local populations from Turkey at 2021. The experiment was established according to the randomized blocks design with three replications. 50% flowering period, maturation time, main stem number, main stem length, main stem thickness, pod length, pod width, number of pods per plant, number of seed per pod, thousand-seed weight, seed yield, biological yield, harvest index and protein ratio were determined. According to the results obtained; 50% flowering period between 211.00-205.33 days, maturation period between 263.33-269.00 days, number of main stems between 4.00-5.67, main stem length between 95.67-58.00 cm, main stem thickness between 1.67-2.07 mm, pod length between 3.67-3.23 cm, pod width between 10.33-11.93 mm, number of pods per plant between 16.63-24.87, number of seeds per pod between 2.97-4.00, thousand-seed weight between 129.23-162.17 g, seed yield between 174.80-234.90 kg/da, biological yield between 392.40 642.10 kg/da, harvest index between 35.73-46.57% and protein ratio show an alteration between 27.71-28.88%. Significant differences were determined between grass pea cultivars and populations in terms of the investigated characteristics. Number of pods per plant, harvest index and protein ratio characteristics were found to be high at populations; flowering and maturation period, main stem length, pod width, thousand-seed weight, seed yield and biological yield characteristics were found to be high at cultivars.
