Seed Color Character Identification and Correlation Analysis on Snap Bean Germplasm Resources

Seed color character identification and correlation analysis on 1 073 snap bean germplasm resources were studied.The results showed that 8 seeds color characters presented obvious trend.Most stem color,leaf color and fresh pod color were expressed green.Most dry pod color was expressed straw color.There was no obvious trend on seed coat color.Cotyledon color,hypocotyl color and corolla color had obvious correlation.If cotyledon color and hypocotyl color were expressed green,corolla color was mostly expressed white or pink.If cotyledon color was expressed dot or purple and hypocotyl color was expressed light red or purple,corolla color was mostly expressed light purple or purple.
