国审玉米新品种泊玉26的丰产性、稳产性及适应性分析

Analysis on High Yield, Stable Yield and Adaptability of New National Approval Maize Cultivar Boyu26

泊玉26是河北省泊头市蔬宝种业有限公司以自交系A98为母本,自交系C62为父本组配的玉米杂交种,2021年通过国家农作物品种审定委员会审定。本研究利用方差分析、Shukla变异系数等方法对泊玉26的丰产性、稳定性和适应性进行分析和综合评价。结果表明,泊玉26较对照品种郑单958增产极显著,具有良好的丰产性;在黄淮海地区增产点率高、变异系数小,具有良好的稳产性和广适性。泊玉26适宜在河南省、山东省、河北省保定市和沧州市的南部及以南地区、陕西省关中灌区、山西省运城市和临汾市、晋城市部分平川地区、安徽和江苏两省淮河以北地区、湖北省襄阳地区等玉米夏播区种植。

Boyu26 was a hybrid maize produced by Shubao Seed Industry Co.Ltd.in Botou City,Hebei Province,with inbred line A98 as the mother and inbred line C62 as the father,which was approved by the National Crop Variety Certification Committee.In this study,variance analysis and Shukla coefficient of variation were used to analyze and comprehensively evaluate the high yield,stability and adaptability of Boyu26.The results showed that the yield of Boyu26 was significantly higher than that of Zhengdan958,showing better production performance.Because of the higher yield increase point rates and the smaller coefficient of variation,Boyu26 had good stability and wide adaptability in the Huanghe-Huaihe-Haihe zone.Boyu26 was suitable for planting in summer maize sowing areas such as Henan Province,Shandong Province,southern and southern areas of Baoding City and Cangzhou City of Hebei Province,Guanzhong Irrigated area of Shaanxi Province,Yuncheng City and Linfen City of Shanxi Province,part of Pingchuan area of Jincheng City,north of Huaihe River area of Anhui and Jiangsu Province,Xiangyang area of Hubei Province,etc.
