摘　　要：通过分析三个寒地水稻品种株高与颖花数的相关性,得知三个品种的株高在一定区间内与颖花数之间具有显著和极显著的相关性。其中龙粳31和龙粳21的株高与颖花数存在极显著的正相关,三江6号的株高与颖花数存在显著的正相关,而且,这种正相关呈直线回归关系。Through analyzing the correlation between plant height and spikelet number of three rice varieties in cold region,it was found that there was significant and extremely significant correlation between plant height and spikelet number of three rice varieties in a certain range.The plant height of Longgeng-31 and Longgeng-21 was significantly positively correlated with the number of spikelet,and the plant height of Sanjiang-6 was significantly positively correlated with the number of spikelet,and the positive correlation showed a linear regression relationship.
