Abstract:

59 cultivated peanuts were registered by Henan Province, since establishment of crop variety examination and approval system. The results of the regional test of peanut showed that there were great changes in average yield, the highest yield, quality, resistance and agronomic traits. The average production was 4306.35 kg/hm2 between 2006 and 2009, which was 615 kg/hm2 higher than that was 3694.05 kg/hm2 between 1982 and 1990. Meanwhile, the average high yield was 6345.90 kg/hm2, which was 415 kg/hm2 higher than that was 5879.55 kg/hm2. The results showed that yield of registered peanut cultivars could be raised year by year, the resistances of new released peanut varieties were significantly higher than that of the check cultivars. Average quality of new released peanut was no significant improvement although qualities of individual species had obviously improved. The key of further improving yield were reduced the height, appropriate increasing in branch, increasing of mature pods per plant and 100-pod weight.
