小麦新品种开麦1502丰产性、稳产性、抗逆性及品质分析

Analysis of High Yield,Stable Yield,Stress Resistance and Quality of New Wheat Variety Kaimai 1502

开麦1502是开封市农林科学研究院粮食研究所选育的半冬性小麦新品种,2020年通过河南省主要农作物品种审定委员会审定(豫审麦20200006)。根据2017—2019年河南省小麦新品种区域试验和生产试验数据,利用增产率、高稳系数和变异系数等指标对开麦1502的丰产性、稳产性、抗逆性及品质进行分析,以期为该品种的大面积推广及合理利用提供参考。结果表明,开麦1502平均产量为8280.00 kg/hm^(2),较对照品种周麦18平均增产5.10%,平均增产点率为91.13%;开麦1502产量的变异系数小,平均为8.83%,高稳系数(平均为87.33%)高于周麦18(平均为82.90%),具有较好的稳产性,且非严重倒伏点率为100%,在品质方面达到河南省中筋小麦标准。可见,开麦1502在丰产性和稳产性方面表现优异,同时还具有良好的抗倒伏性,品质鉴定结果为中筋小麦品种,适宜大面积推广应用。

Kaimai 1502 is a new half‑winter wheat variety bred by Cereal Crop Institute of Kaifeng Academy of Agriculture and Forestry Sciences.It was approved by Henan Province Main Crop Varieties Certification Committee in 2020(Yushen Mai 20200006).According to the data of regional test and production test of new wheat varieties in Henan Province from 2017 to 2019,increase rate of yield,high stability coefficient,coefficient of variation and so on were used to analyze high yield,yield stability,stress resistance and quality of Kaimai 1502,in order to provide reference for the large‑scale promotion and rational utilization of this variety.The results showed that the average yield of Kaimai 1502 was 8280.00 kg/ha,increased by 5.10% compared with the control variety Zhoumai 18 and the average yield point rate was 91.13%.The average yield variation coefficient of Kaimai 1502 was 8.83%,and its high stability coefficient(87.33%)was higher than that of Zhoumai 18(82.90%).Kaimai 1502 had better yield stability,and the rate of non‑serious lodging point was 100%.The quality of Kaimai 1502 reached the standard of medium gluten wheat of Henan Province.It can be seen that Kaimai 1502 has excellent performance in high yield and stable yield,and also has good lodging resistance,whiling the quality identification results show that it is a medium gluten wheat variety,which is suitable for large‑scale application.
