![]() ![]() Large scale rapid screening previously has been done for fatty acid profile in groundnut, major wood characteristics in Eucalyptus ( 15, 16). It is known for various advantages when compared to traditional procedures, including rapid determination, non-destructive, minimal usage of reagents, and less analysis of costs ( 14). NIRS is a non-destructive technique widely used to predict organic compounds of grain material based on electromagnetic radiation ( 13). For the evaluation of a large number of accessions, NIRS has been proven to be a better technique. of crosses/lines each year, but it is difficult to evaluate conventionally through complex methods which are labor intensive, time taking and technically complex. Despite the fact that crop improvement programs produce a large number no. Huge variability exists in the nutritional attributes of cowpea, i.e., starch, protein, phenolics, phytates, TDF, and even in micronutrients ( 12) along with genetic relationships the variability in biochemical traits could help to develop new cultivars with superior traits. In cowpeas 0.5–3/100 g phytates has been reported ( 8, 11). It has the ability to chelate divalent cations like Fe, Mg, and Cu, decreasing the bioavailability of the minerals. Phytates are distributed widely in cereals and legumes, mostly stored in the form of phosphate in seeds. Polyphenols are present in an abundant proportion in legumes, which helps in imparting anti-oxidant properties ranging from 46.5 to 119.6 mg GAE/100 g ( 9, 10). A number of bio-functional non-nutrients are present in dry cowpea seeds like phytates, flavonoids, and tannins ( 8). It is a leguminous crop rich in TDF (16–20 /100 g), lowering the risk of cardiovascular diseases, diabetes and heart ailments ( 7). High starch in cowpea can be used to make processed products like moin-moin and akara ( 6). It is rich in protein (24/100 g), total dietary fiber (11/100 g), carbohydrates (60/100 g), and low in fatty acids (<2/100 g), with a significant amount of essential amino acids 1. Owing to its high nutritional value, cowpea can be a good food source to combat malnutrition in low income developing countries, especially in Asian and African countries ( 5). In India, it is grown as a minor pulse in an area of 3.9 mha with a production of 2.21 million tons ( 4), mainly in the arid and semi-arid tracts of Haryana, Punjab, Delhi, and Western Uttar Pradesh. Nigeria accounts for 40% of total cowpea production, followed by Niger (26.8%) and Burkina Faso (7.3%). In Sub-Saharan Africa, Asia, and parts of America, it is a significant pulse crop, grossing a total world production of 8.9 million metric tons ( 3). Cowpea ( Vigna unguiculata (L.) Walp.) is one such multipurpose legume originating from Africa ( 1), that may facilitate in providing food security and is adaptable to climate change and harsh conditions ( 2), becoming a successful crop in arid and semi-arid areas. Legumes have high nutritional qualities, are suitable for soil health and show resilience to climate change these attributes can help to attain food security among low income developing nations of the world. ![]() These prediction models will facilitate high throughput screening of large cowpea germplasm in a non-destructive way and the selection of desirable chemotypes in any genetic background with huge application in cowpea crop improvement programs across the world. For all the traits worked, p-value ≥ 0.05 implied the accuracy and reliability score >0.8 (except phenol) ensured the applicability of the models. ![]() Models for all the traits displayed RPD values of >2.5 except phenols and low SEP indicating the excellent prediction of models. Higher RSQ external values such as 0.903, 0.997, 0.901, 0.706, and 0.955 were obtained for protein, starch, TDF, phenols, and phytic acid respectively. NIRS prediction models were developed to assess protein, starch, TDF, phenols, and phytic acid based on MPLS regression. NIRS is a technique used to rapidly determine biochemical parameters for large germplasm. Assessing nutritional traits conventionally can be laborious and time-consuming. Cowpea ( Vigna unguiculata (L.) Walp.) is one such legume that can facilitate achieving sustainable nutrition and climate change goals. ![]()
