高产优质耐盐碱玉米新品种富民105的选育及苗期盐碱胁迫浓度筛选
Breeding of New Maize Variety Fumin 105 and Concentration Screening of Saline-Alkali Tolerance at Seedling Stage
摘要
Abstract
In order to promote the popularization and application of the new maize variety Fumin 105 with high yield,high quality and saline-alkali resistance,the selection process,characteristics,cultivation techniques and the screening of suitable saline-alkali stress concentration were introduced in this paper.Fumin 105 is a middle and late maize hybrid bred by Jilin Fumin Seed Industry Co.,Ltd.with Fm1101 as the mother and F1 as the father.From 2017 to 2018,Fumin 105 participated in the regional experiment of high density group in Jilin Province,and the average yield of the two-year regional experiment was 12 674.9 kg·ha-1,which was 3.9％higher than that of Xianyu 335,the control variety.In 2018,it participated in the production test of high density group in Jilin Province.The average yield of the production test in 2018 was 11 941.7 kg·ha-1,which was 5.1％higher than that of the control variety Xianyu 335,showing a significant increase in yield.In the simulated stress environment of 0,50,100,150 and 200 mmol·L-1 Na2CO3 solution,the salt damage of maize varieties at seedling stage under Na2CO3 stress was compared.It was found that Fumin 105 leaves had better green retention and stronger salt-alkali tolerance than Xianyu 335 leaves under 100 mmol·L-1 Na2CO3 solution.In 2018,it was approved by the Jilin Provincial Crop Variety Certification Committee,and the certification number is Jishenyu 20190027.This variety has the characteristics of high yield,high quality,suitable ripening stage,strong disease resistance,wide adaptability and salt-alkali tolerance.关键词
