| Abstract: | 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. |
