High temperature during the reproductive stage limits the growth and development of lentil (Lens culinaris Medikus). The reproductive and seed filling periods are the most sensitive to heat stress, resulting in limited yield and nutritional quality. Climate change causes frequent incidents of heat stress for global food crop production. This study aimed to assess the impact of high temperature during the reproductive stage of lentil on grain yield, nutritional value, and cooking quality. Thirty-six lentil genotypes were evaluated under controlled conditions for their high temperature response. Genotypic variation was significant (p < 0.001) for all the traits under study. High temperature-induced conditions reduced protein, iron (Fe) and zinc (Zn) concentrations in lentils. Under heat stress conditions, mineral concentrations among lentil genotypes varied from 6.0 to 8.8 mg/100 g for Fe and from 4.9 to 6.6 mg/100 g for Zn. Protein ranged from 21.9 to 24.3 g/100 g. Cooking time was significantly reduced due to high temperature treatment; the range was 3–11 min, while under no stress conditions, cooking time variation was from 5 to 14 min. Phytic acid variation was 0.5–1.2 g/100 g under no stress conditions, while under heat stress conditions, phytic acid ranged from 0.4 to 1.4 g/100 g. All genotypes had highly significant bioavailable Fe and moderately bioavailable Zn under no stress conditions. Whereas under heat stress conditions, Fe and Zn bioavailability was reduced due to increased phytic acid levels. Our results will greatly benefit the development of biofortified lentil cultivars for global breeding programs to generate promising genotypes with low phytic acid and phytic acid/micronutrient ratio to combat micronutrient malnutrition.

“…The average per capita availability of pulses for human consumption slightly increased in low-and middle-income countries since the 1990s from 7.30 kg in 1995 to 7.94 kg in 2007; representing a growth rate of 0.8% per year (Akibode and Maredia, 2012). The demand for pulses continues to increase in line with the growing population and rising per capita incomes (Sharasia et al, 2017;Li and Siddique, 2018).…”

Long-life cycle pulses have significant food security potential, however, there is little evidence to explain why they are not more widely produced and consumed in sub-Saharan Africa (SSA). This study aimed at exploring existing knowledge to inform on future research priorities in mainstreaming superior species. As staple food along with cereals, pulses are an important source of nutrients whose intake is often inadequate in SSA, however, pulse consumption remain inadequate in SSA. Depending on the crop's life cycle, pulses have multiple functions that can support food systems and ecosystem resilience. Compared to short-life cycle pulses, long-life cycle pulses rank higher in multipurpose role. However, prior research has focused primarily on short-life cycle pulses due to rapid grain production. Long-life cycle pulses remain underutilized and neglected despite showing steady but modest yield increases and adaptation to environments, suggesting that they are better positioned to respond to the diverse needs of smallholder farmers in SSA. In the context of climate change, rain-fed agriculture, depleted agricultural soils, and lack of subsidized fertilizers, there is need to transform existing food systems toward sustainable food production and improved resilience. Increasing pulse agrobiodiversity by integrating long-life cycle pulses in existing farming systems could not only contribute in alleviating malnutrition, but also poverty and inequalities. In addition, representative and accurate data are needed based on the correct use of accepted scientific names for all data across the food system. This is a prerequisite for assessing pulse consumption adequacy and quantifying production and consumption trends.

“…Common bean ( Phaseolus vulgaris L., 2 n = 2 x = 22) is the most widely consumed legume grain in the human diet ( Broughton et al 2003 ) and a valuable source of protein, energy, and micronutrients for more than 300 million people in the developing world ( Gepts et al 2008 ; Blair et al 2010 ; Petry et al 2015 ). Its relevance to global food security is becoming increasingly important due to markedly high population growth in the leading common bean consumption countries ( Akibode and Maredia 2011 ; Bellucci et al 2014 ) and the rising importance of protein resources of vegetable origin ( Petrusán et al 2016 ; Kumar et al 2017 ). Brazil is one of the largest consumers and producers of common bean, harvesting around 3 million metric tons per year ( FAOSTAT 2018 ).…”

Seed weight and size are important yield components. Thus, selecting for large seeds has been a key objective in crop domestication and breeding. In common bean, seed shape is also important since it influences industrial processing and plays a vital role in determining the choices of consumers and farmers. In this study, we performed genome-wide association studies (GWAS) on a core collection of common bean accessions to dissect the genetic architecture and identify genomic regions associated with seed morphological traits related to weight, size and shape. Phenotypic data was collected by high-throughput image-based approaches, and utilized to test associations with 10,362 SNP markers using multi-locus mixed-models. We searched within genome-associated regions for candidate genes putatively involved in seed phenotypic variation. The collection exhibited high variability for the entire set of seed traits, and the Andean gene pool was found to produce larger, heavier seeds than the Mesoamerican gene pool. Strong pairwise correlations were verified for most seed traits. GWAS identified marker-trait associations accounting for a considerable amount of phenotypic variation in length, width, projected area, perimeter and circularity in four distinct genomic regions. Promising candidate genes were identified, e.g., those encoding an AT-hook motif nuclear-localized protein 8, type 2C protein phosphatases and a protein Mei2-like 4 isoform, known to be associated with seed size and weight regulation. Moreover, the genes that were pinpointed are also good candidates for functional analysis to validate their influence on seed shape and size in common bean and other related crops.
