摘要
以河南、山东等5个花生主要产区培育的19个高油酸花生新品种为材料,于2019年~2021年连续3年在郑州种植,采集3年间花生关键生育期(6月~9月)的旬平均气温、旬降水量和旬日照时数等气象数据,结合各个品种的产量数据进行综合分析.研究结果表明,不同的品种对于气温、降水量和日照时数的敏感程度不同,冀花16、冀花11对开花下针期的温度和日照时数比较敏感,该时期的异常高温会致使其产量明显下降.中花413、中花412和花育917的产量与旬降水量成显著负相关,耐涝程度较差.对品种的稳定性分析表明,开农1768、南充1704、冀农16、开选016、花育961、郑农花25、郑农花23、冀农11、花育633和1508G等10个高油酸品种为年际间稳定性较好的品种,研究结论为高油酸品种的培育及深入利用提供了指导.
Abstract
To explore the effect of different meteorological conditions on the yield of high oleic acid peanut,19 varieties derived from 5 main peanut producing areas,such as Henan and Shandong province,were planted in Zhengzhou from 2019 to 2021,meteorological data such as 10-day average temperature,10-day precipitation and 10-day sunshine hours during the key growth period of peanuts(from June to September)were collected,and the yield data of each variety were combined for comprehensive analysis.The results showed that the varieties had dif-ferent response to temperature,precipitation and sunshine hours.Jihua 16 and Jihua 11 were more sensitive to tem-perature and sunshine hours at flowering and peg setting stage.The abnormal high temperature at this stage would cause the yield to drop significantly.The yields of Zhonghua 413,Zhonghua 412 and Huayu 917 were significantly negatively correlated with 10-day precipitation,and be least tolerance to waterlogging.The stability analysis of vari-eties showed that 10 varieties with high oleic acid,including Kainong 1768,Nanchong 1704,Jinong 16,Kaixuan 016,Huayu 961,Zhengnong 25,Zhengnong 23,Jinong 11,Huayu 633 and 1508G,had good inter annual stability.The research provides guidance for the cultivation and further utilization of high oleic acid varieties.
