    摘要:

    本文对吉林省8个中晚熟主栽耐密玉米杂交种进行综合分析与评价。结果表明:所有品种达到国家一级玉米容重标准,商品品质优良。淀粉含量农华101最低,为淀粉普通型玉米;禾玉33最高,达到74.86%,其次是良玉208和吉单558,这3个品种达到国家高淀粉玉米二级标准;先玉335、迪卡516、郑单958、良玉188淀粉含量为三级,这7个品种可作为高淀粉玉米品种进行推广种植。产量表现为农华101>良玉208>吉单558>郑单958>先玉335>良玉188>禾玉33>迪卡516。品种产量方差分析表明,区组间差异不显著,品种间差异显著。指出品种种植中应注意的事项。

    Abstract:

    Eight main cultivars of high density tolerant medium to late maturing maize hybrids of Jilin Province were comprehensively analyzed and evaluated in the paper.The results showed that all cultivars met the national first class standard of maize bulk density,and their commodity quality was superior.Starch content of ‘Nonghua 10’ was minimum,so it was starch ordinary type of corn;Starch content of ‘Heyu 33’ was the highest,reaching 74.32%,followed by ‘Liangyu 208’ and ‘Jidan 558’,these three species reached the national second class high-starch corn standard;Starch content of ‘Xianyu335’ ‘DK516’, ‘Zhengdan958’ and ‘Liangyul88’ reached the third class standard,this seven varieties can be planted as high-starch corn varieties.Yield performance was as following order: ‘Nonghua 101’ > ‘Liangyu208’ > ‘Jidan 558’ > ‘Zhengdan 958’ > ‘Xiangyu 335’ > ‘Liangyu 188’ > ‘Heyu 33’ > ‘DK 516’.Variety Yield analysis of variance showed that the difference among groups was not significant,it was significant among varieties.Notes for selecting cultivar in planting maize were pointed out.
