Breeding of Yangnonggeng 3426 and Its Supporting Cultivation Techniques
摘要
Abstract
Yangnonggeng 3426 is a conventional early-maturing late geng(japonica)rice variety characterized by moderate plant height,semi-compact plant architecture,uniform population,strong lodging resistance,and favorable senescence with green stems and yellow grains at maturity.This variety was approved for commercial release in Jiangsu Province in 2023(Approval Number:Sushendao 20230018).Regional trial results demonstrated that Yangnonggeng 3426 had a total growth period of 155.5 days,which was 2.5 days shorter than that of the control variety Wuyungeng 23.The variety had the characteristics of an average height of 100.8 cm,approximately 211 000 panicles per 667 m2,average grains per panicle of 127.1,a seed-setting rate of 94.4%and a 1 000-grain weight of 30.3 g.The variety showed moderate susceptibility to rice blast,bacterial leaf blight,and rice stripe virus disease,and was susceptible to sheath blight.The rice quality met the Grade 3 standard of the Cooking Rice Variety Quality(NY/T 593-2021).This paper introduces the breeding process,main agronomic traits,and key cultivation techniques of Yangnonggeng 3426,aiming to provide a scientific basis for its further promotion and application.关键词
