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.
