通过抽样调查 ,对几个优质早稻品种的产量及产量因素进行相关分析和通径分析 ,结果表明 :优质早稻的增产潜力较大 ;各品种增产的主攻方向不同 ,赣早籼 4 8、99- 0 6、早香玉以培育大穗作为主攻方向。各品种增产途径不同 ,在高产量水平下 ,以增粒为主 ,主攻大穗 ,提高结实率和千粒重 ;在中低产量水平下 ,以增穗为主、兼顾粒数 Through sampling survey, the yield and yield factors of several high-quality early rice varieties were analyzed and the path analysis was carried out. The results showed that the yield potential of high-quality early rice was larger and the yield of different varieties was different. 0 6, asparagus to cultivate the big spike as the main direction. The yield of different varieties of different ways, at high levels of production, mainly to grain, the main big spike, and improve the seed setting rate and 1000-grain weight; in the low-yield level, to increase ear, taking into account the number of particles
