摘　　要：抗旱性是作物与干旱环境相互作用的复杂数量性状,准确的抗旱表型鉴定是挖掘抗旱基因和开展抗旱遗传研究的基础,对于水稻节水抗旱育种至关重要。在大田条件下进行稻种资源全生育期抗旱表型鉴定的方法一直是抗旱育种工作者所关注的技术难题。本文针对这一问题,在多年田间稻种资源抗旱性鉴定和研究的基础上,对抗旱性鉴定体系进行探索优化,总结制定了稻种资源全生育期田间抗旱性鉴定的技术规程,其内容包括一般要求、整地、种植方式、水分管理、施肥、病虫草害防治以及抗旱性评价等全过程的操作规范和基本要求,以期为稻种资源全生育期抗旱鉴定提供技术参考。该技术规程适用于海南省三亚市每年冬季(11月中旬至次年4月上旬)的田间种植的全生育期抗旱性鉴定。Drought resistance is a complex quantitative trait of the interaction between crops and drought environment,accurate evaluation of drought resistance phenotype is the basis for mining drought resistance genes and exploring drought resistance genetics,it is very important for water-saving and drought-resistant rice breeding.The method system for the evaluation of drought resistance of rice germplasm during whole growth periods in the field has always been a technical problem concerned by drought-resistant breeding workers.Aims at this problem,we exploring and optimizing the conditions for assessing drought resistance based on many years of the evaluation and research of rice drought resistance in the field.The standard technical regulations for drought resistance evaluation in the field of rice germplasm during whole growth periods were summarized and normalized.It mainly includes general requirements,land preparation,the methods of planting,water management,fertilization,prevention of diseases,pests and weeds and drought resistance evaluation,so as to provide technical reference for drought resistance evaluation of rice germplasm during whole growth periods.The technical regulations are applicable to the evaluation of drought resistance during whole growth periods during the winter in Sanya city,Hainan province(from mid-November to early-April of the next year).
