The objective of this study was to evaluate Andean genotypes for CT, PHD, and seed iron and zinc concentration. A total of 52 genotypes belonging to three market classes, namely, purple-speckled (Kabulangeti), yellows, and cranberry (sugar beans), were grown at the Golden Valley Agricultural Research Trust (GART) Farm and the Mpika Research Farm in Zambia and assessed for CT, PHD, and seed iron and zinc concentration. The fastest cooking genotype among all 52 genotypes was a yellow genotype, Y1612-5. Yellow genotypes generally cooked faster than the Kabulangeti and sugar types. Among the elite lines with Kabulangeti seed types, which is a dominant market class in Zambia, the elite line K175 had faster CT and higher iron and zinc concentration than the Kabulangeti landrace race currently available on the Zambian market. Kabulangeti and sugar genotypes showed regular darkening, whereas yellows did not darken. The yellow genotype Y1612-3 was particularly outstanding because of its unique combination of high concentrations of both iron and zinc. Therefore, it can be used to introgress these two essential minerals into variable genetic backgrounds. The significant variability and high to moderate heritability for CT (0.85) and iron (0.81) and zinc (0.58) concentration observed in the current study suggest that it is possible to make progress in breeding for faster cooking varieties that are rich in iron and zinc.","PeriodicalId":17929,"journal":{"name":"Legume Science","volume":"6 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/leg3.70012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142451722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Expanding its cultivation in southern Africa requires high-yielding, locally adapted and drought-tolerant varieties. This study determined the combining ability and genetic components for seed yield and related traits in tepary bean genotypes under non-stress (NS) and drought-stress (DS) conditions. Seven parents were selected through rigorous phenotyping and crossed using a half-diallel design. The 7 parents and 21 F2 progenies were evaluated in 2021/2022 season at Kasinthula and Bunda sites in Malawi under NS and DS conditions using a 4 × 7 lattice design with three replications. The specific combining ability (SCA) × location interaction effect was significant (p < 0.05) for DTF, NPP, and SY, suggesting that the genetic effects of crosses were influenced by the test locations. General combining ability (GCA) and SCA mean squares were significant for the number of seeds per pod (NSP) and SY under DS conditions, indicating both additive and non-additive gene effects. Baker's ratio (BR) > 0.50 for NPP and NSP under DS conditions suggested a preponderance of additive gene effects. G40145, G40148 and G40150 parental lines were good combiners for NPP and SY. The F2 families from crosses such as Zimbabwe landrace/G40138, Zimbabwe landrace/G40150, G40059/G40145, G40059/G40148, G40138/G40150 and G40145/G40150 were identified as best specific combiners, with enhanced SY of 1.67 t/ha under DS conditions.

As a result, 232 million people are suffering from microelement deficiency and 239 million from protein-calorie malnutrition in Africa. This study evaluated the nutritional quality of common bean grain harvested from 63 genotypes planted at Malkerns in Eswatini. The results showed significantly marked differences in the concentrations of 10 dietarily important nutrient elements. Of the macronutrients, Na levels showed the highest variation (12.00–91.00 mg/g) among the 63 bean genotypes, followed by K (14.03–22.03 mg/g) and P (3.30–9.57 mg/g), with Mg (1.57–2.30 mg/g) and Ca (0.80–2.68 mg/g) concentrations exhibiting the least difference among the bean genotypes. Of the micronutrients, Fe levels revealed the highest variation (66.36–151.08 mg/kg), followed by Zn (23.57–70.72 mg/kg) and Mn (11.53–26.84 mg/kg), with B (10.06–17.65 mg/kg) and Cu (6.30–13.67 mg/kg) exhibiting relatively lower differences among the 63 common bean genotypes. However, genotype NUC 461 recorded the highest grain concentrations of P, K, Mg, Fe, Cu, Zn, and B, followed by DAB 155, which also revealed high levels of P, K, Ca, Fe, Zn, and Mn in its seeds. For improved human health and nutrition, the two bean genotypes would be the ideal candidates to recommend to commercial bean growers and resource-poor farmers.

Functional properties of these ingredients were investigated, including overall solubility, protein solubility, water-holding, oil-holding, emulsifying, foaming and rheological properties. DF proteins exhibited higher protein solubility, higher emulsification and lighter colour, while WF proteins demonstrated higher water-holding capacity. The pasting profiles varied significantly between the two processing methods, with DF proteins exhibiting lower pasting temperatures. However, the gels formed from DF and WF proteins exhibited similar abilities to withstand deformation and retain their structure. The findings highlight that the fractionation method significantly influences the functional properties of protein materials. Dry fractionation may produce materials with high solubility, offering significant potential in food applications.","PeriodicalId":17929,"journal":{"name":"Legume Science","volume":"6 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/leg3.70005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142360003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While India and Canada are the largest modern-day producers, Australia is a close third and the second largest exporter of lentil globally. An overview of lentil introduction cultivar development and production in Australia since the 1960s is presented. This commenced with obtaining international germplasm, and in the 1970s, Australia participated in the ICARDA-led Food Legume Improvement Program (FLIP), which saw the release of nine varieties in the span of a decade. The first local breeding efforts in Australia commenced in the 1990s through the Coordinated Improvement Program for Australian Lentils (CIPAL), which transitioned into Pulse Breeding Australia (PBA) in the 2000s, and saw the first Australian-bred varieties released in 2008. Currently, Agriculture Victoria's National Lentil Breeding Program and Grains Innovation Australia (GIA) breed and release varieties for Australian lentil growers, and future perspectives for their programmes are presented. One of the main diseases of lentil is Ascochyta blight, which is caused by the fungus Ascochyta lentis. The discovery of a major avirulence gene within Australian A. lentis populations which determines pathotype has allowed recent categorisation of a collection of isolates, and their response to Australian varieties is discussed. The narrowing gene pool and viability of interspecific hybridisation of Australian lentil is additionally explained. Taken together, this review summarises the history and pedigree of Australian varieties and lentil breeding, the impact of major disease pathotypes on cultivar utility and the pursuits of public and private lentil breeding initiatives.","PeriodicalId":17929,"journal":{"name":"Legume Science","volume":"6 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/leg3.70006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142328468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, legume-based edible coatings are gluten free and acceptable to consumers with dietary restrictions for coatings derived from nonplant sources. Their use in edible coating further extends the economic significance of legumes. The physicochemical properties of these coatings may vary based on several factors including composition of the film, conditions of processing, and additives used. Legume-based edible coatings and films hold the ability to enhance the shelf life and quality of food items by acting as barriers against oxygen, moisture, and solute transfer. Also, they can aid in maintaining the nutritional value, flavor, and sensory qualities of food products. Incorporation of bioactive compounds, such as antioxidants and antimicrobials, into legume-based coatings further enhances their functionality in food preservation.
