Longhongxiaodou 1 was a new red bean variety bred by crossing with the parental combination of Jingchuanhong xiaodou-2/Jihong 1. The average yield of Longhongxiaodou 1 was 1 903.1 kg/hm2 and 15.7% higher than of the check Jingchuan-hongxiaodou-2 which was conducted during the period 2009-2011 in the regional test . The results showed that Longhongxiaodou 1 was upright, semi-determinate podding habit, and growth period, plant height, plant branches, pods per plant pod, pod length, 100-grain Weight were 98 d, 31.8 cm, 4.3 branches, 34.6 ind, 7.8 pod, 8.6 cm, 23.6 g, respectively . The results also indicated that content of crude protein in grain(dry base), crude starch(dry base), crude fat(dry basis), water (dry basis) were 233.1 mg/kg, 535.2 mg/kg, 4.10 g/kg, 13.1%, respectively . It was high resistance to leaf rust field, representing resistance to a leaf spot .
