Studies on Physico-chemical Characteristic of Some Varieties/ Genotypes in Various Brassica Species

Abstract

The present study was conducted in the laboratories of the Department of Agricultural Biochemistry to evaluate thirty nine varieties/genotypes of Brassica Species for physical and chemical characteristics such as moisture content, Test weight, Oil content, Protein content in meal and Methionine content in meal. The samples was collected from University farm as well after grading of the sample the quality analysis in the laboratory was conducted as per standard procedures. Moisture content in different varieties/genotypes of yellow sarson varied from 5.60 to 3.25% while toria entries varied from 5.05 to 3.48%. In case of rai the range of variation was 5.67 to 3.56%. Test weight in different varieties/genotypes of yellow sarson varied from 5.70 to 3.40 g/1000 seed, while toria entries varied from 5.10 to 3.50 g/1000 seed. In case of rai the range of variation was 4.28 to 3.23 g/1000 seed. Oil content in different varieties/genotypes of yellow sarson varied from 42.55 to 36.20%, while toria entries varied from 42.05 to 34.40%. Whereas rai entries recorded variability of 39.05 to 32.40%. Protein content in different varieties/genotypes of yellow sarson varied from 40.55 to 27.93%, while toria entries varied from 30.03 to 28.33%. In case of rai the range of variation was 31.10 to 28.95%. Methionine content in different varieties/genotypes of yellow sarson varied from 1.98 to 0.99 g/100g, while toria entries varied from 2.12 to 1.14 g/100g. In case of rai the range of variation was 1.84 to 1.22 g/100g.
