NUTRITIONAL STUDY OF SOME ADVANCED MUTANT LINES OF GROUNDNUT (Arachis hypogaea)

Abstract

Groundnut, popularly known as "chinabadam" is the second most important oil seed crop in Bangladesh, after mustard (Brassica spp.) in terms of annual production. It is used as an edible oil in the food industry to produce cake, cookies, and baked goods. It plays an important role in human nutrition containing high protein, calories, minerals, and vitamins. Binachinabadam-6 and four advanced mutant lines derived from it, B6/282/63, B6/282/64, B6/282/80 and RM-Kha-19 were studied to investigate the qualitative properties of the genotypes and to find potential groundnut genotypes which can be released as variety. Among the 5 selected genotypes oil content were observed from 54.6% to 48.5%. Myristoleic acid (2.463-0.009%), oleic acid (55.7-29.977%), linoleic acid (17.129-13.691%), erucic acid (3.035-1.634%) as unsaturated fatty acids and hexanoic acid (23.291-4.232%), lauric acid (4.742-1.302%), palmitic acid (8.6601.044%), arachidic

acid (28.455-16.829%) were estimated as saturated fatty acids. O/L ratio (3.68-1.75) and iodine value (74.12-53.71) were calculated from fatty acid components. Ca (85.54-74.12 mg/100g), Mg (173-148 mg/100g), S (89-56 mg/100g), N (5190-4370 mg/100g), P (490-360 mg/100g), K (730-650 mg/100g) as major minerals and Fe (2.15-1.62 mg/100g), Zn (5.9-3.8 mg/100g), Cu (1.5-0.5 mg/100g), B (3.6-2.4 mg/100g) were estimated as minor minerals. Other properties i.e protein (32.42-27.34%), ash (2.38-2.23%), crude fiber (3.71-3.52%), carbohydrate (11.4- 5.57%) and total energy (628.4- 594.58%) were also observed. Considering all the findings, B6/282/80 was the best performer among all mutants in this study.
