摘　　要：本试验选取黑龙江省春小麦育种史上有典型代表性的"克字号"春小麦系列品种作为研究对象,在多年小麦育种及栽培研究的过程中发现各品种无效小码数在年际间存在差异,因此选取14个春小麦品种进行调查并分析,结果表明:无效小码数与年际间的气候变化有一定的关系,从整体上气候正常年份较不正常年份无效小码数明显减少,其中孕穗期的降水量与温度至关重要。In the test, 'Ke' series spring wheat varieties are selected as the research objects, which are typical, representative in the breeding plants history in Heilongjiang province , in many years of wheat breeding and cultivation process invalid spikelet numbers of each variety have difference between the different years, so we choose 14 plants varieties for investigation and analysis, and the results showed that: invalid spikelet numbers and climate change between the different years has a certain relationship , invalid spikelet numbers significantly reduced in a normal year, compared with the ones in the year with abnormal climate, especially the rainfall and temperature in the stage of booting is very important.
