Twenty-one elite rice genotypes were evaluated at the ICAR-Indian Institute of Rice Research, Rajendranagar, Hyderabad at the time of the Kharif 2021 and Rabi 2023 seasons to investigate the correlation among yield as well as many yield attributing characters which include days to 50percent flowering, plant height (PH), number of tillers (NT), length of panicle (PL), panicle weight (PW), number of productive tillers (NPT), number of unfilled grains (NUFG), number of filled grains (NFG), single plant yield(SPY), fertility of spikelet (SF), and test weight (TW). During the kharif season of 2021, there exists a robust and statistically significant association among the characteristics of individual plant yield and the weight of the panicle. The traits that showed a positive correlation with the SPY in Kharif 2021 were PH, PL, NT, NPT, SF, PW, NFG, and TW. These traits suggest that they must be considered as criteria of selection in programs of yield improvement. In Rabi 2023, a single plant has a positive correlation with TW, filled as well as unfilled grains, NT, PW, and NPT. According to correlation studies, the yield of grain/plant invariably increases with an increase in one or more of these characteristics.","PeriodicalId":296228,"journal":{"name":"International Journal of Research in Agronomy","volume":"281 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141708184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, poor crop establishment due to environmental stresses hinders DSR success. This study evaluates 17 rice genotypes under DSR for growth, yield parameters and suitability. The plant height, leaf area, dry matter production, yield attributes like productive tillers, panicle length, seed yield and duration to maturity were assessed. Significant genotypic variations were observed for most parameters except unfilled spikelets per panicle. MTU-1010 demonstrated consistently superior field emergence, plant height, leaf area, dry matter accumulation and number of productive tillers compared to other genotypes. It also had highest seed yield (64.08 q/ha) across years. The results emphasize the importance of traits like vigorous seedling growth and tillering ability in determining DSR success. Flowering duration showed significant differences among genotypes, with early varieties being desirable for uniform fields and climate resilience. However, very early maturity may compromise yield potential. MTU-1010 had moderately late flowering and maturity while producing top yields, indicating a complex relationship between these traits under stress. The findings identify MTU-1010 as a promising genotype for DSR cultivation, with potential for further improvement through breeding efforts enhancing its useful traits. The study underscores need for varieties combining high yield potential, vigorous early growth and improved storage ability. Continued research on genotypes, agronomic management and sustainable practices is imperative to make DSR a viable alternative to transplanted rice. Overall, this study provides valuable insights into rice genotypes suitability for DSR and traits influencing productivity","PeriodicalId":296228,"journal":{"name":"International Journal of Research in Agronomy","volume":"42 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141695362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
