东北早熟区花生品种产量优化分析

Optimization of the Yield of Peanut in Northeast Early-Maturing Region

本研究对吉林省近年来选育、引进综合性状较好的10份花生新品种在吉林不同生态区域的5个试验点进行对比试验。应用Shukla稳定性方差分析方法确定适宜吉林省不同生态环境区域的花生新品种,同时综合评价不同品种在不同生态环境区域的丰产性、稳定性与适应性。试验结果表明,吉花19和吉花20增产达到极显著水平,稳产性好,建议在全省花生产区作为主推品种示范推广;双花2号、青花6号、吉花11和吉花4号产量中等,稳产性一般,建议作为搭配品种推广应用。

10 peanut varieties released or introduced lately were compared and analyzed in five ecological regions of Jilin Province.The suitable peanut varieties for different ecological regions were determined by Shukla methods.Their productivity,stability and adaptability to five ecological regions were comprehensively evaluated.The resultsshowed that‘Jihua 19’and‘Jihua 20’were suggested as the main promotion variety in Jilin Province because ofhigh and stable yield.‘Shuanghua 2’,‘Qinghua 6’,‘Jihua11’and‘Jihua 4’were suggested as secondary varieties for their productivity and yield stability were in common.
