Abstract

Abstract:

This article introduced the breeding process, characteristics and key cultivation techniques of Degeng 5, and discussed the breeding route of japonica rice in the low latitude plain and hilly areas of Southwest China. Degeng 5 is a new mid maturity conventional japonica rice variety selected by Rice and Sorghum Reserarch Institute, Sichuan Academy of Agricultural Sciences through the pedigree method, suitable for planting in the low-latitude plain hilly area of Southwest China and has the characteristics of high temperature resistance, high quality, and low rice accumulation of cadmium. This variety was approved by the Sichuan Provincial Crop Variety Approval Committee in 2023.

Key words: japonica rice, high quality, high temperature resistance, low cadmium accumulation

摘要：

本文介绍了德粳5号选育过程、特征特性及栽培技术要点，讨论了西南低纬平丘区粳稻育种路线。德粳5号是四川省农业科学院水稻高粱研究所通过系谱法选育而成的适宜西南低纬平丘区种植的中熟常规粳稻新品种，具有耐高温、优质、籽粒镉低积累等特性。该品种于2023年通过四川省农作物品种审定委员会审定。
