Stady of adaptability lathyrus advanced lines, in cold moderate and tropical areas in dry land conditions

This experiment was conducted in 3 stations: Kermanshah, Gachsaran and Lorestan Abstract: (Kohdasht) in 3 years. Our aim in these trials was identification of lathyrus sativus superior lines which had high-yield and suitable characteristics adaptive to dry land condition. In this experiment we studied 15 lines and our experimental design were RCBD with 3 replications. Each line was planted in 8 rows with 4 meters length. Datas were analysed after harvesting biological, grain and wet yield. Bartelett,s test for homogeneity of variances (in combined analysis) showed: all of the stations had not the equal experimental error variance.The results showed that simple and intraction effects had significant difference in statistical level of 1 percent in biological, grain and wet yeild in Sararood, Gachsaran and Lorestan stations in 1385-1387 . In underinvestigation areas number 3(Sel 474), 1(Sel 515) and 5(Sel 689), genotypes had the most biological yeild (6241, 6123, and 6100 Kgr/ha ) respectively in 1385 year.In 1386 year, genotypes number 3(Sel 474), 11(Sel 678) and 5(Sel 689), genotypes had the most biological yeild (8706, 7830 and 7816 Kgr/ha) respectively.Genotypes number 3(Sel 474) ,12(Sel 736-1) and 9(Sel 554), had the most biological yeild (3582,3372 and 3287 Kgr/ha) respectively in 1387 year. In underinvestigation areas number 8(Sel 1307), 5(Sel 689) and 12(Sel 736-1), genotypes had the most grain yeild (1891, 853 and 1840 Kgr/ha respectively) in 1385 year.Genotypes number 3(Sel 474), 9(Sel 554) and 7(Sel 669), had the most grain yeild (2187,2007and 1875 Kgr/ha) respectively in 1386 year. In 1387 year, genotypes number 8(Sel 1307), 3(Sel 474) and 4(Sel 1329), genotypes had the most grain yeild (731,686, and 682 Kgr/ha) respectively. In underinvestigation areas number 5(Sel 689), 9(Sel 554) and 3(Sel 474), genotypes had the most wet yeild (19859, 19022 and 17709 Kgr/ha respectively) in 1385 year.Genotypes number 11(Sel 678), 12 (Sel 736-1) and 3(Sel 474), had the most wet yeild (23028, 21370 and 20969 Kgr/ha respectively) in 1386 year. In 1387 year genotypes number1 (Sel 515), 12(Sel 736-1) and 5(Sel 474), genotypes had the most wet yeild (8996, 8955 and 8573 Kgr/ha) respectively. Our investigation in 3 station during 3 years demonstrated that, genotypes number 3(Sel 474), 9(Sel 554) and 5(Sel 689), had the highest biological yeild respectively (6177, 5688 and 5669 Kgr/ha), and genotype number 10(Sel 1332), had the lowest biological yeild (4776 Kgr/ha).Our investigation in 3 station during 3 years demonstrated that, genotypes number 3(Sel 474), 9(Sel 554), and 5(Sel 689), had the highest grain yeild respectively (1548, 1479 and 1454 Kg/ha), and genotype number 10(Sel 1332), had the lowest grain yeild(1269 Kgr/ha). Our investigation in 3 station during 3 years demonstrated that, genotypes number 5(Sel 689), 3(Sel 474) and 11(Sel 678), had the highest wet yeild respectively (15921, 15751 and 15628 Kgr/ha), and genotype number 14(Sel 736-2), had the lowest wet yeild(12280 Kg/ha). Finally we selected 4 lines in Sararood and Lorestan stations, and 7 lines in Gachsaran stations to have preference over among lines under investigation. We will enter them to on farm trial next year.
