بررسی و مقایسه عملکرد لاین های پرمحصول سویا در مناطق مختلف

In order to study and comparison of high-yielding soybean purelines in different regions asmany as 19 soybean purelins with Williams cultivar as check were conducted at three places (Khorramabad-Karaj and moghan) and two years from 2005 to 2006. The statistic design in this study was random completely blocks with 4 replications. During growth season some characters such as days to initial flowering. Date of maturing, days to maturing, plant height and pod per plant were measured on five random plants. After harvesting seed yield was weighted. The results indicated that seed yield in places and years was significant difference at 1% level. Yearاplace intraction for seed yield and other characters was significant at the 1% level. In intraction of the first year and second place (moghan) with 3658kg/ha showed the highest seed yield. Purelines and check cultivare for seed yield were not significant diference but for other characters such as plan height, pod per plant and node per stem were significant diference at 1% level. Line 14 (HackاT.N.5.94) showed the highest seed yield (3206 kg/ha) and lines 10 and 6 were latter ranks. As many as 10 purelines showed yield highest of check. Key word: soybean purelines, yield comparison, different regions.
