| 摘 要： | 品种引进是提高作物产量的重要方式之一,本研究通过两年大田品种比较试验对黑龙港低平原地区引进的9个春花生品种进行生态适应性研究。结果表明:相对于单株饱果数,荚果产量受百果重影响较大,而百果重与百仁重、主茎高、侧枝长、籽仁长极显著正相关,但与总分枝数极显著负相关(P0.01)。与当地种植品种‘冀花4号’相比,‘豫花25’、‘豫花9326’、‘豫花22’具有明显的增产优势,平均籽仁产量分别增加28.95%,17.91%,17.67%,且‘豫花9326’粗脂肪含量较高。综合分析,黑龙港低平原地区通过引进春花生品种‘豫花25’、‘豫花9326’具有较大的增产潜力。

| Abstract: | Variety introduction is one of the important ways of increasing crop yield.A two-year variety comparative experiment on ecological adaptability of 9 spring peanut varieties was conducted,The result indicated:Pod yield was affected by 100-pod weight more than by No.of mature pods per plant,and 100-pod weight was very significantly positively correlated with 100-seeds weight,length of main stem,lateral branch length and seed length,while very significantly negatively correlated with branch number per plant (P＜0.01).Compared with local variety ‘Jihua 4’,the varieties‘ Yuhua 25 ’,‘ Yuhua 9326 ’ and ‘ Yuhua 22 ’ had significant yield superiority,which improved kernel yield by 28.95％,17.91％ and 17.67％ respectivels,and ‘Yuhua 9326’ had relatively higher crude fat content.Taken all together,the introduction of spring peanut varieties ‘Yuhua 25 ’and‘ Yuhua 9326’ was expected to have great potential of yield improvement in Heilonggang low plain area. |
