Breeding and Cultivation Techniques of High-Quality,High-Yield Sweet Waxy Maize Hybrid'Fengtiannuo 4'
摘要
Abstract
'Fengtiannuo 4'is a single-cross hybrid developed with the inbred line SX124 as the female parent and the inbred line SB34 as the male parent.In the regional trial in Hunan,2021,the fresh ear yield averaged 11.78 t/hm2,which represented an increase of 4.1%over the control.In the regional trial in 2022,the average fresh ear yield of'Fengtiannuo 4'reached 12.59 t/hm2,representing an increase of 5.7%over the control.Data from the 2021-2022 regional trials showed an average fresh ear yield of 12.19 t/hm2,representing an increase of 4.9%over the control.The variety exhibited good quality,with amylose(dry basis)accounting for 1.9%of the total crude starch and a total score of 88.9 points for fresh ear quality.Resistance identification results indicated that'Fengtiannuo 4'possessed good lodging and stalk breakage resistance,as well as strong resistance to major diseases such as northern leaf blight,southern leaf blight,and sheath blight.Overall,the variety demonstrated a high yield,good quality,and multiple resistance,with excellent comprehensive performance.It was approved by the Hunan Provincial Crop Variety Appraisal Committee in 2023(Approval No.Xiangshenyu 20230010).This paper systematically describes the breeding process,characteristics,and key supporting high-yield cultivation techniques for'Fengtiannuo 4',aiming to provide a reference for its application and promotion in Hunan Province.关键词
