Evaluation of agronomic characteristics and comparison of yield in International Lathyrus Lines In rainfed conditions at autumn planting.

This experiment was conducted in trials: LGYT-E, LGYT-LO and LGYT-HP Our aim in these trials were to find Upper lines of Lathyrus sativus in dry land condition. In these experiments we evaluated 57 pure lines of Lathyrus sativus with local check in Sararood station. Trials were planted as simple lattice design with 2 replications during autumn, and fertilizers were applied according to N30:P20 formula in the planting time. Some agronomic characteristics including: days to flowering, days to maturity, Plant stand, plant height and biological yield were noted and analyzed. In first trial (LGYT-E), the results showed that number 10 (2096), 5(1345) and 11(1872) had the highest biological yield, between lines under investigation (with 848, 693 and 693 kg/ha respectively). .According of result number 5(1345), 11(1872) and 8(1793), genotypes had the most biological yield (2062, 1958, and 1802 Kg/ha ) respectively. According of result13 (2295) had the most weight of 100 seeds (with 8.4 gr) In Second trial (LGYT-LO) , The results showed that number 16(local check), 2(1330) and 10(B222) had the highest biological yield ,between lines under investigation(with 609 , 510 and 469 kg/ha respectively). .According of result number 9(B111), 16(local check) and 15(1326), genotypes had the most biological yield (1812, 1812, and 1760 Kg/ha ) respectively. According of result 13 (1337) had the most weight of 100 seeds (with 12 gr) In third trial (LGYT-HP) , The results showed that number 6 (2096) , 3(1345) and 19(1940) had the highest biological yield ,between lines under investigation (with 745 , 745 and 685 kg/ha respectively). According of result number 23(1345), 6(2096) and 4(1333), genotypes had the most biological yield (2307, 2151, and 2021 Kg/ha ) respectively. According of result 24 (ETH WIR-70) had the most weight of 100 seeds (with 12.4 gr) Finally we selected Upper lines of Lathyrus sativus in Sararood stations, to have preference over among lines under investigation. We will enter them to adaptation trial next year.
