“…Consequently, participatory variety selection should include the opinions of male and female farmers. Surveys among rice-producing farmers in India reported gender differences in trait preferences and variety selection (Mehar et al, 2017). Tegbaru et al (2020) identified gender-shared and distinct varietal traits in maize.…”

“…Farmer participatory plant breeding or variety selection has been used especially in marginal crops and environments as an important approach to identify varieties adapted to different environments and the needs of different end-users (Adeniji and Aloyce, 2013;Dinssa et al, 2020;Fufa et al, 2010;Ndinya et al, 2020). It is important to consider gender preferences in variety selection because there may be gender differences in trait preferences and rankings (Mehar et al, 2017). Gender-disaggregated participatory maize (Zea mays) variety trials conducted in Benin, Nigeria, and Mali identified gender-shared and distinct varietal traits (Tegbaru et al, 2020).…”

Amaranths (Amaranthus sp.) are a popular leafy vegetable grown and consumed by resource-poor people in many African countries. Greater awareness of the importance of nutritious foods has increased demand by African consumers for amaranth. Presently, most African farmers grow low-yielding local varieties of variable seed quality. High-yielding amaranth varieties that are adapted to the major agro-ecologies of eastern and southern Africa possess key traits needed by male and female farmers and meet diverse market preferences are required. The objective of this study was to identify amaranth lines adapted to major amaranth production environments in Kenya and Tanzania using a gender-disaggregated farmers participatory approach to explore possible gender differences in trait and variety preferences. Twenty amaranth entries were evaluated for vegetable yield, agronomic traits, and organoleptic taste tests in replicated, farmer-participatory variety selection trials at one location in Kenya and at four locations in Tanzania. Differences among entries (G), locations (E), and G × E interaction were significant or highly significant for marketable vegetable yield. Location followed by entry was the most important factor that explained differences in yield. G and G × E interaction biplot analysis classified the five locations into two different mega-environments, mainly based on altitude, temperatures, and soil characteristics. Marketable vegetable yield was positively correlated with leaf length, plant height, and the selection scores of female and male farmers at almost all locations. Selection scores of female and male farmers were positively correlated, indicating that male and female farmers shared similar amaranth variety preferences. Farmers identified and ranked important traits that can be used by breeders to design amaranth product profiles and develop amaranth breeding objectives. Lines combining high yield with high farmer and consumer preference scores have been retained for distinctiveness, uniformity, and stability tests for possible release as commercial varieties.

“…Hong Kong prefers long-grain, low-amylose rice with a softer gel consistency, while sticky rice is preferred in Laos, Korea, and Japan (Juliano, 1993). Customers in North India favour rice with aromatic long grains (Mehar et al 2017). To satisfy the market's expectations for rice of varied desirable qualities that are locationspeci c, it is necessary to investigate grain quality criteria.…”

Background: The demand for quality rice is increasing due to the influence of population growth and rising living standards. North eastern region of India is considered as centre of origin of rice and has diversified rice landraces with unique cooking quality and yield attributing traits. The studies on genetic diversity and marker-trait association analysis of north-eastern hilly rice for grain quality and yield attributes are of enormous importance for the identification of promising rice genotypes with better grain and cooking quality vis a vis markers associated with grain quality and yield attributes. This will assist in development of high-yielding cultivars. Results: Genetic diversity among 130 rice genotypes of North East India and marker-trait association was assessed using genotypic data of 90 SSR markers and phenotypic data. The phenotypic diversity analysis showed considerable variation across genotypes for grain quality, yield and yield-attributing traits. The principal component analysis revealed that plant height, panicle length, spikelet fertility, decorticated grain length and width, days to maturity, days to 50% flowering, and grain yield govern the diversity. Population structure analysis, distance-based neighbour joining cluster and principal coordinate analysis using genotypic data grouped the genotypes into two sub-populations. Analysis of molecular variance and pairwise FST values showed significant differentiation among all the pairs of sub-population. Marker trait association analysis using the mixed linear model revealed a total of six associations at P < 0.0001 for grain quality and yield attributing traits with R2 ranging from 3.55 to 11.91% under the upland ecosystem. The present study validated the association of RM240 marker with Gel consistency for use in MAS and existence of plant height gene on chromosome 3. The study indicated the presence of novel QTLs for days to maturity with RM210 and RM105 and days to flowering with RM101 under consideration. Conclusions: The present study suggests that the diverse germplasm of NE India and identified markers could be used in rice breeding programs for the improvement of grain quality and yield attributes.
