Study on yield and agronomic characteristics of Faba Bean populations in Gorgan mountain region

The objective of this study was to compare yield of faba bean lines and selection of superior lines which have high yield, early maturity, large seed size ,plant type . This experiment was conducted with 4 lines and check( Barkat ) in a R.C.B design with four replications in Shakoo mountain region during one year.Each line was planted in 10 rows with 10 meters long and between row spacing of 60 cm . During growth stage characterstics were measured such as sprouting date , flowering date, plant type, plant height , number of pods , number of seeds per pod,pod length,Green-pod weight,dry seed weight and maturity.The result of analysis of variance showed that experimental treatment effect was significant at 1% level on pod length and significant at 5% level of probability on number of seeds per pod, number of pods per plant and number of stem per plant. Comparison of green-pod yield showed that line Histal and Aquadulce respectively with 17759 and 13055 kg/ha produced the highest yield line Histal had 20 % higher yields than check (Barkat). In Comparison of dry seed yield, line Histal produced the highest yield with 2743 kg/ha and line ILB 1814 with 1577 kg/h had The least yield ; the line Aquadulce was the second line as yield. Check (Barkat) had 1577 kg/ha yield. In Comparison of yield components line Histal with 10.7 number of pods per plant, with 28.5cm pod length, 5.2 number of stem per plant and 6.3 and 6.3 number of seeds per pod was superior variety .Correlation between green-pod yield with number of pods per plant and pod length were positive significant at 5% level of probability respectively (0.50) and (0.44).Also significant correlation positive at 1% level of probability was between dry seed yield with number of seeds per pod (0.62). Therefore line Histal was selected for as an introducable line for Gorgan mountain region
