Correlation Analysis Between Yield and Agronomic Traits of Low Density Planted Fresh Faba Bean Varieties
To select early maturing fresh faba bean varieties suitable for cultivation around Qilu-Lake,nine varieties were introduced for variety comparison experiments,and correlation analysis was conducted on the main agronomic traits and yield of different varieties.The results showed that pod length,fresh weight per 100 pods,and number of pods per plant were closely related to yield.Increasing any one of the three traits would promote yield while ensuring that other factors remained unchanged.The tested faba bean varieties showed inconsistencies in the growth of flowering and podding periods.The early flowering and podding periods of'Yundou Zao 6'and'Yundou Zao 7'of the faba bean varieties were earlier than that of other varieties,and the podding periods were the longest.'Yundou Zao 6'and'Yudou 3'had good yield potential in the study area,but the high and stable yield between the years and the regions needs further experimental study.
