玉米新品种德丰717甘肃省生态适应性分析
|
摘要
以沈单16为对照,按随机区组设计,于2013—2016年统计中晚熟玉米新品种德丰717在4个水地组试验点、5个旱地组试验点的生育期、农艺性状、抗病性、穗部性状以及丰产性。结果表明,德丰717生育期与沈单16相当;农艺性状均优于对照;抗病性综合特性良好;穗部性状具备高产的群体优势特征;丰产性优于对照。品种效应、地点效应和年份效应分析表明,与对照相比,德丰717增产稳定,不受环境和种植年份影响,有较强的生态适应性。
Using Shendan 16 as the control, randomized block design was adopted. The growth period, agronomic characters, disease resistance, ear characters and yielding ability of middle or late-maturing maize variety Defeng 717 in four irrigation groups and five dryland groups were researched in 2013-2016. Results showed that growth period of Defeng 717 was equal to that of Shendan 16, but its agronomic characters were superior to the control. Moreover, Defeng 717 had good comprehensive characteristics of disease resistance, its ear characters had group dominance characteristics of high yield. Analysis of variety effects, site effects and year effects showed that compared with the control, Defeng 717 had stable yield increase, was not affected by the envoironment and planting years, having relatively strong ecological adaptability.
