To this achieved, 21 F1 hybrids developed from seven parental genotypes using half diallel mating design and assessed under normal and water stress at Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt. The grain yield and most traits significantly differ (<i>p</i> < 0.01) between genotypes and their partition; parents, crosses, and their interaction as well general combining ability (GCA) and specific combining ability (SCA). Water stress significantly reduced grain yield and all traits in parents and hybrids compared to normal conditions. Also, most parents and hybrids significantly favor GCA and SCA effects for grain yield and all traits, respectively. Best mean performances, stress tolerance index (STI) and desirable GCA effects are noticed by SaKha108, Giza179. Based on principal component analysis (PCA), these parents can be used for generating superior rice hybrids under water stress. The hybrid combinations Giza177 × Azucena, Sakha108 × Azucena and Giza179 × Azucena discovered to be good specific combiners for grain yield and majority traits under water stress. For all traits, there were strong correlations among F1 hybrids’ performance, SCA and heterosis estimations. The above genotypes and these traits correlated could be exploited for improving rice grain yield and drought tolerance in future breeding programs.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 1","pages":"10 - 25"},"PeriodicalIF":1.4,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49005105","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}

Recognizing the significance of alternate wetting and drying technology in sustainable agriculture, this study aims to promote the adoption of this technology among both Good Agricultural Practices (GAP) and non-GAP farmers in Suburban, Bangkok, Thailand. Data were collected through a structured questionnaire, which gathered information on farmers' cost and return values, as well as their adoption opinions. The collected data were then analyzed using cost and return analysis, as well as stochastic frontier analysis. The results indicate that non-GAP farmers face significantly higher total costs due to increased fixed costs compared to GAP farmers. While there were no significant differences in yield between the two groups, GAP farmers achieved significantly higher total income and net profit due to lower total costs and higher selling prices. Furthermore, the analysis suggests that both groups of rice farmers have the potential to improve their efficiency levels, with non-GAP farmers showing a higher potential for improvement. In terms of adoption opinion, both farmer groups recognize the advantages of wet and dry farming technology over traditional flooded rice farming. This study highlights that the adoption levels of both GAP and non-GAP farmers can be significantly improved through the implementation of best management practices. Overall, the findings emphasize the importance of trustworthy information dissemination to encourage the adoption of wet and dry farming technology, as it enhances farmers' trust in the received information and their engagement with the technology. The study concludes by providing policy implications and recommendations to promote the wider adoption of wet and dry farming technology.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 1","pages":"169 - 181"},"PeriodicalIF":1.4,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45300811","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}

For example, MRQ 88 was an aromatic, long and slender shape with non-sticky Basmati features while other varieties were characterized by sticky, soft and aromatic which is similar to the existing fragrant rice in the market. Therefore, the study attempts to explore the specific characteristics of fragrant rice that influence the consumer’s purchasing decision. A face-to-face survey was conducted involving 774 respondents in Peninsular Malaysia, Sabah and Sarawak using a structured questionnaire with selected criteria of respondents. Conditional logit (CL) in Choice Experiment (CE) analysis was then conducted. The results showed the choice of attributes that were significant at a 1% level were softness (moderate and very soft), aromatic, and non-stickiness stated at the moderate level of preference. These factors were identified to influence consumers’ choice of preferences in purchasing fragrant rice. The highest level of softness showed the most important attribute that influenced the willingness to pay followed by the attribute of moderate aroma. However, the attribute of non-stickiness/moderate flakiness shows a relatively low value of willingness to pay. Hence, the development of fragrant rice characteristics should consider the highest level of softness with a moderate level of aroma and non-stickiness as a priority.
