بررسی روابط صفات فنولوژیک، مورفولوژیک، اجزای عملکرد و عملکرد در ارقام سویا

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), Katul(DPX) and Sahar(Pershing). 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 charavters had prime importance role on seed yield.
