摘要: 在大田和小区试验中对不同株、穗型水稻超高产品种产量构成等进行了研究, 结果表明: 半直立穗型品种穗数、穗粒数与
产量呈显著正相关, 但通径分析结果表明, 对产量直接正向作用的是穗数, 穗粒数对产量为负向作用; 直立穗型品种对产量起正向
作用的是穗粒数和千粒重, 弯曲穗品种对产量起正向作用的是穗数。

Abstract: The result of study indicated: the yield of sem-i erect type had a significant positively correlated w ith panicles and spik elets per
panicle, the result of latus rectum analysis indicate th e panicles had a positive relation w ith yield; the spik elets per panicle had negative rela-
tion w ith yield1 The yield of had a positive relation w ith th e spikelets per panicle of erect type, and w ith th e panicles of curve type1
Key words:rice; super high-yield; plant type; panicle type; yield
