Abstract:

Abstract: This paper analyzed the main characteristics of Xiangzaoxian46 and the yield component of six experiment points in Hunan Hejiashan Original Breeding Farm. The aim was to fully tap the yield potential of Xiangzaoxian46 and increase further its production. The results showed that Xiangzaoxian46 were better than Jinyou402 in plant height, spikelets per panicle, seed set and 1000-grain weight; resistant to lodging and piricularia leaf spot of rice,Moderate to bacterial leaf blight; In analysis of production structure, the coefficient of variation of effective panicles and spikelets per panicle was large, a large significant positive association was found for yield, and the equation on linear regression is y=-24923.7+27.6x1+39.5x2+173.4x3+215.8x4. In cultivation and management, we should research the effective panicles and spikelets per panicle and coordinate the relationship between grains per spike.
