Abstract:

In order to evaluation of relationship among phenological and morphological traits, yield components, seed and in soybean varieties , an experiment was laid out in split-plot based on randomized complete block design with four replications at Dashtenaz region of Mazandaran province in 2013. Main plot was seed rates including 55, 70 and 85 kg.ha-1 and sub sub plots were six soybean cultivars including Sari (JK), Telar (BP), Caspian (033), Nekador (032), Katol (DPX) and Sehar (Pershing). Results showed that seed rates had significant effects on all the traits. The varieties were different for all the traits. Non-significant interaction effects of seed rates and cultivars for most of the traits except duration of flowering and first pod height from earth indicating that variations of the traits of each cultivar had similar trend in different seed rates. Average seed yield of the genotypes for 55, 70 and 85 kg.ha-1 were 2999, 3246 and 2700 kg.ha-1, respectively.The results of correlation analysis showed that duration of flowering was affected by days to flowering and days to maturity. 1000-seed weight had significant positive correlation with days to flowering and duration of flowering, indicating the same directions of variation of these traits. Seed yield had significant positive correlation with yield components including pods per plant, 1000-seed weight, harvest index, indicating these component characters had prime importance role on seed yield.
