Our experiment, therefore, aimed to identify high potential indigenous upland rice varieties for grain yield and yield stability under rainfed conditions. Fifty upland rice genotypes were evaluated from 2013 to 2015, in which a randomized complete block design with three replications was laid out over the three years. Based on grain yield, eight indigenous upland rice varieties, including ULR026, ULR042, ULR075, ULR078, ULR080, ULR081, ULR089 and ULR105; demonstrated superior performance, high yield stability, and greater adaptability over the other varieties, including the Sew Mae Jan check variety. Additional qualities of the superior varieties included high amylose content (ULR081 and ULR075), high aroma (ULR078), and intermediate gelatinization temperature test (GT) (ULR078, ULR026, and ULR105). The participatory varietal selection (PVS) test for farmer(s) acceptance, and promotion of these varieties under rainfed conditions will be further studied.</p></div>","PeriodicalId":54198,"journal":{"name":"Annals of Agricultural Science","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aoas.2020.09.004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47116496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
