摘  要:
研究了小麦在模拟杂交育种F3种植模式下的边行优势,结果表明,公顷穗数和千粒质量的边行优势非常明显,达到1%的极显著水平;二者均为边Ⅰ行的边行优势最大,边Ⅲ行最小;穗粒数无明显的边行优势。因此,对杂交后代进行选择时,应注意公顷穗数和千粒质量边行优势的影响,以便于更准确地对各株行进行预测和选择。

摘  要:
Wheat marginal superiority was studied under the simulated planting pattern of the third cross breeding progeny. The results showed that there were significant differences in the marginal superiority of hectares ear number and 1 000-grain quality(P<0.01). It showed the maximum value in hectares ear number and 1 000-grain quality of rowⅠ, while it showed the minimum value in hectares ear number and 1 000-grain quality of row Ⅲ. There were no significant differences in grains per ear. Therefore, it should be pay attention to the effect of marginal superiority of hectares ear number and 1 000-grain quality while selecting the hybrid progeny so as to forecast and select accurately to each row.
