Rice is the main staple for more than half of the world’s population. In Ghana, rice is the fastest growing food commodity, and it is consumed by almost every household. However, yields continue to be low, as the pace of adoption of new varieties is low. The low rate of adoption has been attributed to failure of modern breeding to incorporate preferred traits for end users. This study thus employed an innovative set of breeding tools, the G+ tools, in identifying gendered trait preferences to develop a robust product profile through a mixed-method approach. The assertion that “men focus more on production and marketing related traits as women focus on production and cooking qualities” was also ascertained. Descriptive, inferential and content analyses were conducted, and the results indicate ecological differences in varietal choices. Production and marketing traits are jointly preferred by the gender groups. However, women and young women paid attention to post-harvest and cooking quality traits. The gender impact scores generated indicated there are tradeoffs in the traits preferred. These findings highlight the significance of recognizing geographical differences and gender heterogeneity in relation to varietal and trait preferences. In conclusion, the outcomes emphasize the necessity of gender-sensitive breeding work that considers the various needs and trait priorities of targeted men and women rice farmers in breeding decisions for a robust rice product profile.
Balimau Putih [an Indonesian cultivar tolerant to rice tungro bacilliform virus (RTBV)] was crossed with IR64 (RTBV, susceptible variety) to produce the three filial generations F 1 , F 2 and F 3 . Agroinoculation was used to introduce RTBV into the test plants. RTBV tolerance was based on the RTBV level in plants by analysis of coat protein using enzyme-linked immunosorbent assay. The level of RTBV in cv. Balimau Putih was significantly lower than that of IR64 and the susceptible control, Taichung Native 1. Mean RTBV levels of the F 1 , F 2 and F 3 populations were comparable with one another and with the average of the parents. Results indicate that there was no dominance and an additive gene action may control the expression of tolerance to RTBV. Tolerance based on the level of RTBV coat protein was highly heritable (0.67) as estimated using the mean values of F 3 lines, suggesting that selection for tolerance to RTBV can be performed in the early selfing generations using the technique employed in this study. The RTBV level had a negative correlation with plant height, but positive relationship with disease index value.www.blackwell-synergy.com
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
