Abstract: To study the flowering and podding habit of different kidney beans varieties, ninety thousand plants/hm~2, one hundred and fifty thousand plants/ hm~2 and two hundred and ten thousand plants/hm~2 three planting density were set with England red and Pinyun 2 kidney beans. The result showed that： two species of flowering order was center → bottom →top, and the pod rate was between 23.8% and 43.3%;two varieties on the pod number per plant and seed weight per plant were presented down trend, while production was rising trend with the increase of planting density;as the development of growth period, two varieties of different processing on the grain fresh weight were first rise then falling, and the grain dry weight were rising trend.Seed dry weight reached maximum at mature period.
