ANALYSIS OF CORRELATION BETWEEN PHYSICAL, NUTRITIONAL, AND ANTINUTRITIONAL COMPONENTS IN MUNGBEAN GENOTYPES

Mung bean (Vigna radiata L.) is a widely consumed pulse, especially in Asia, known for its high protein, fiber, vitamins, essential amino acids, and minerals like calcium, magnesium, and potassium.However, it also contains antinutritional factors such as trypsin inhibitors, tannins, phytic acid, saponins, and polyphenols, which can reduce its nutritional value.Therefore, it is crucial to evaluate genotypes with higher nutritional content and lower levels of antinutrients.The seeds of improved mungbean genotypes were analysed for physical characteristics, proximate composition, limiting amino acids, minerals and antinutritional constituents.The significant variations in seed coat colour of mungbean genotypes was observed and ranged from olive green to pale olive green or dark green, the hundred seed weight, seed volume seed density and grain hardness were ranged from 3.82-5.14g, 3.60-5.20ml, 1-1.27 g/ml, 306.25-429.93N respectively The proximate analysis revealed significant differences in content of moisture (9-10%); crude protein (18.37-21.76%);crude fat (0.95-1.97%); crude fiber (3.50-4.50%);carbohydrate (61.70-63.01%);ash (3-3.60%).Limiting amino acids viz.methionine and tryptophan ranged from 0.81-0.94and 0.69-0.91g/16 g N respectively.Proteins of most of cultivars were found deficient in methionine and tryptophan as compared to FAO (1977) values viz.2.4 and 1.2 g/16g N respectively.The content of phosphorus, calcium, magnesium, iron and zinc in mungbean genotypes were ranged between 270.28-353.46,137.50-172.57,162.82-190.75,7.03-9.22,0.95-1.30mg/100g respectively.So, it was found that selected mungbean genotypes are good source of minerals like phosphorus, calcium and magnesium while iron and zinc content in these genotypes found to be sufficient.Analysis revealed significant differences in content of polyphenols (340.78-361.67 mg/100g).The genotypes with coloured seed coat contained higher number of polyphenols phytate phosphorus (63.20-69.65 mg/100g) with; trypsin inhibitor (12.10-14.17TIU/mg).From these results it appears that genotypes are found to be promising for lowest content of these antinutritional constituents.Based on above results it can be concluded that genotypes Phule Chetak, Kopergaon, Vaibhav, PM-707-27 and PM-818-8 were found to be promising for nutritional composition, limiting amino acids, minerals and antinutritional constituents.
