“…Combined with relatively low cost and wide access to the poor, pulses are characterized as "poor man's meat" (Malo and Hore, 2020). The variability observed for whole-grain protein in the present study (23.35-29.50%) was higher than the protein content (16.76-26.82%) reported in previous studies (Amarteifio et al, 2002;Sekhon et al, 2017;Obala, 2018;Cheboi et al, 2019;Choi et al, 2020;Jawalekar et al, 2020) and is comparable with the dhal protein content of high protein lines (27-29%; Saxena et al, 1987). The protein content in dhal is higher than that in the whole grain (Susmitha et al, 2022), signifying that dhal nutritional analysis of the superior accessions in this study may still have higher protein than the high protein lines reported by Saxena et al (1987).…”

“…Nutritionally, pigeonpea grain is rich in protein, Ca, Mn, and crude fiber (Saxena et al, 2010). The variability for protein content, reported in previous studies, varied from 16.7 to 26.8% (Amarteifio et al, 2002;Sekhon et al, 2017;Obala et al, 2018;Cheboi et al, 2019;Choi et al, 2020;Jawalekar et al, 2020), whereas, in wild species, the range is from 16.3 to 33.8% (Upadhyaya et al, 2013). Very few studies enumerated mineral composition in pigeonpea (Singh et al, 1984;Oshodi et al, 1993;Amarteifio et al, 2002;Mishra and Acharya, 2018).…”

Grain Nutrients Variability in Pigeonpea Genebank Collection and Its Potential for Promoting Nutritional Security in Dryland Ecologies

et al. 2022

Pigeonpea, a climate-resilient legume, is nutritionally rich and of great value in Asia, Africa, and Caribbean regions to alleviate malnutrition. Assessing the grain nutrient variability in genebank collections can identify potential sources for biofortification. This study aimed to assess the genetic variability for grain nutrients in a set of 600 pigeonpea germplasms conserved at the RS Paroda Genebank, ICRISAT, India. The field trials conducted during the 2019 and 2020 rainy seasons in augmented design with four checks revealed significant differences among genotypes for all the agronomic traits and grain nutrients studied. The germplasm had a wider variation for agronomic traits like days to 50% flowering (67–166 days), days to maturity (112–213 days), 100-seed weight (1.69–22.17 g), and grain yield per plant (16.54–57.93 g). A good variability was observed for grain nutrients, namely, protein (23.35–29.50%), P (0.36–0.50%), K (1.43–1.63%), Ca (1,042.36–2,099.76 mg/kg), Mg (1,311.01–1,865.65 mg/kg), Fe (29.23–40.98 mg/kg), Zn (24.14–35.68 mg/kg), Mn (8.56–14.01 mg/kg), and Cu (7.72–14.20 mg/kg). The germplasm from the Asian region varied widely for grain nutrients, and the ones from African region had high nutrient density. The significant genotype × environment interaction for most of the grain nutrients (except for P, K, and Ca) indicated the sensitivity of nutrient accumulation to the environment. Days to 50% flowering and days to maturity had significant negative correlation with most of the grain nutrients, while grain yield per plant had significant positive correlation with protein and magnesium, which can benefit simultaneous improvement of agronomic traits with grain nutrients. Clustering of germplasms based on Ward.D2 clustering algorithm revealed the co-clustering of germplasm from different regions. The identified top 10 nutrient-specific and 15 multi-nutrient dense landraces can serve as promising sources for the development of biofortified lines in a superior agronomic background with a broad genetic base to fit the drylands. Furthermore, the large phenotypic data generated in this study can serve as a raw material for conducting SNP/haplotype-based GWAS to identify genetic variants that can accelerate genetic gains in grain nutrient improvement.

“…However, these values vary with genotype and across different studies ( Talari and Shakappa, 2018 ). Biochemical evaluation of a total of 55 genotypes comprising advanced lines, improved cultivars, and landraces resulted in the identification of variation in four parameters: crude protein content (16.7%–28.4%), total phenol (21.9–84.4 mg/100 g), total flavonoid (16.4–33.4 mg/100 g), and total antioxidant activity (19.2–82.5 mg/100 g) ( Cheboi et al, 2019 ).…”

Mining legume germplasm for genetic gains: An Indian perspective

Legumes play a significant role in food and nutritional security and contribute to environmental sustainability. Although legumes are highly beneficial crops, it has not yet been possible to enhance their yield and production to a satisfactory level. Amid a rising population and low yield levels, per capita average legume consumption in India has fallen by 71% over the last 50 years, and this has led to protein-related malnutrition in a large segment of the Indian population, especially women and children. Several factors have hindered attempts to achieve yield enhancement in grain legumes, including biotic and abiotic pressures, a lack of good ideotypes, less amenability to mechanization, poorer responsiveness to fertilizer input, and a poor genetic base. Therefore, there is a need to mine the approximately 0.4 million ex situ collections of legumes that are being conserved in gene banks globally for identification of ideal donors for various traits. The Indian National Gene Bank conserves over 63,000 accessions of legumes belonging to 61 species. Recent initiatives have been undertaken in consortia mode with the aim of unlocking the genetic potential of ex situ collections and conducting large-scale germplasm characterization and evaluation analyses. We assume that large-scale phenotyping integrated with omics-based science will aid the identification of target traits and their use to enhance genetic gains. Additionally, in cases where the genetic base of major legumes is narrow, wild relatives have been evaluated, and these are being exploited through pre-breeding. Thus far, >200 accessions of various legumes have been registered as unique donors for various traits of interest.

Pigeon pea (Cajanus cajan L.) is one of the most important legume crops grown in subtropical and tropical regions with high nutritional quality. However, the consumption of pigeon pea is very limited worldwide owing to its high level of anti‐nutrients, hard texture, and unpleasant characteristic taste. The present review summarized the nutritional profile and health benefit of pigeon pea with special attention to its bioactive phytochemicals (e.g., cajanin, cajanol, and cajaninstilbene acid). Furthermore, some aspects that can help promote the application of pigeon pea in foods were highlighted from the perspectives of physical (i.e., thermal, extrusion, and ultrasound‐assisted), chemical (i.e., chemical modification and enzymatic hydrolysis), and biological treatment (i.e., sprouting and fermentation). The primary impact of physical methods was confined to the mitigation of anti‐nutrients. Chemical approaches were less explored and mainly targeted on the modification of starch and protein in pigeon pea. In contrast, the biological methods were found to decrease the level of anti‐nutritional factors, increase the production of bioactive phytochemicals, and improve the sensory properties of pigeon pea. Therefore, biological methods, especially sprouting techniques, are considered to be more promising.
