摘要
This study was conducted to determine seed yield and its affecting components in grasspea lines (Lathyrus sativus L.), supplied from ICARDA (International Center for Agricultural Research for Dry Areas, Aleppo, Syria), in ecological conditions of Diyarbakir, in Southeastern Turkey, with winter sowings, during three consecutive years, 2008-09, 2009-10 and 2010-11. The field trials were performed according to randomized blocks design with three replications. According to the averages of the combined three years; the investigated traits had ranges as follows: Days to physiological seed maturity - 208.6-211.7 days; the number of pods per plant - 20.0-34.0 pod plant(-1); the number of seeds per pod - 3.08-3.72 seed pod(-1); seed yield - 188.3-309.2 kg da(-1); biological yield - 528.2-847.1 kg da(-1); straw yield - 318.3-551.5 kg da(-1); harvest index - 32.0%-42.8% and 1000 seed weight - 89.3-136.5 g. According to results of GGE Biplot analysis; while 2008-09 and 2009-10 growing seasons were found near to each other, 2010-11 growing season was found different the two growing seasons considering all of the investigated traits. Additionally; the investigated eight traits made up three groups, and seed yield, biological yield, straw yield, 1000 seed weight and days to physiological seed maturity traits took part in the first group. Sel 706 (6), Sel 681 (4), Sel 2999 (12) and Sel 666 (1) lines were found as promising lines respectively in terms of the first group traits.
