保加利亚玉米品种在黑龙江省种植适应性研究

Study on Adaptability of Bulgaria Maize Hybrids in Heilongjiang Province

对从保加利亚引进的10个玉米品种进行了引种试验。结果表明:在参试品种中,KH614和KH611M的产量较高,比对照增产显著,可在黑龙江省的各适宜生态区进行进一步试验、示范。参试的该批杂交种在平均株高、穗位高方面均低于对照,表明部分杂交种在降低株高穗位及提高抗倒伏性方面可能具有潜在的间接利用价值。

Ten maize hybrids introduced from Bulgaria were planted in Harbin. The results showed that the yield of KH614 and KH611M were increased obviously comparing with CK in the tested varieties. It was suggested that the future KH614 and KH611M should be tested and demonstrated in Heilongjiang province. These maize hybrids＇s plant and ear height were remarkable lower than CK. It indicated that these hybrids had potential indirect application value in shortened plant and ear height and promoted the lodging resistance.
