分析了广西2016—2023年审定的135个常规稻品种主要性状和产业发展形势,认为广西优质常规稻品种存在稻瘟病抗性水平低、稻米品质指标协调性差、主效基因缺乏、同质化严重、低镉型品种选育滞后、销售及转让价格低等问题,对配套栽培技术的研究和推广也不足。针对当前广西优质常规稻育种及产业存在的问题提出解决对策,如加强分子育种,提高品种品质和稻瘟病抗性,加快选育镉低积累品种,加大优质稻品种推广力度,研发和推广配套保优高产栽培技术,打造高端品种优势品牌。

After analyzing the main traits and industrial development situation of conventional rice varieties approved in Guangxi from 2016 to 2023, it is believed that Guangxi’s high quality conventional rice varieties have problems such as low resistance to rice blast, poor coordination of rice quality indicators, lack of major effect genes, serious homogenization, lagging breeding of low cadmium varieties, and low sales and transfer prices. Additionally, there is insufficient research and promotion of supporting cultivation techniques. Proposed solutions to the existing problems in the breeding and industry of high quality conventional rice in Guangxi, such as strengthening molecular breeding, improving variety quality and resistance to rice blast, accelerating the selection of cadmium-low-accumulation varieties, increasing the promotion of high-quality rice varieties, researching and promoting supporting high-yield cultivation techniques, and creating a high-end brand.
