Abstract

Five different varieties of rice viz., Shalimar Rice-I, Jhelum, K-332, China-1039 and Pusa Sugandh grown under temperate climatic conditions of India were taken for the investigation. Physical characteristics of paddy including grain length, grain breadth, length-breadth ratio, 1000-kernel weight, hectoliter weight, density and moisture were measured and ranged from 7.19 to 11.75 mm, 2.49 to 3.18 mm, 2.35 to 4.45, 23.54 to 30.21 g, 45.58 to 58.82 kg/hl, 0.45 to 0.58 g/cc and 10.75 to 13.07, respectively. Husked rice ranged from 73.53 to 80.39%, milling recovery 68.44 to 72.77%, milling degree 79.69 to 93.20%, milling efficiency 69.34 to 79.71%, head rice 43.80 to 63.70%, broken rice 8.41 to 22.68%, bran 10.77 to 13.52% and husk 16.49 to 21.45%. The physical characteristics of rice ranged from 4.58 to 7.16 kernel length (mm), 1.41 to 2.34 kernel breadth (mm), 2.13 to 5.07 l/b ratio, 17.15 to 22.59 1000-kernel weight (g), 77.67 to 83.70 hectolitre weight (kg/hl), 0.77 to 0.83 density (g/cc) and 9.37 to 11.33 chalkiness (%). Moisture, ash, fat, protein, total sugars, starch, amylose and amylopectin of test varieties were found in the range of 10.40–11.92%, 0.36–0.51%, 0.22–0.51%, 7.29–8.72%, 0.72–0.78%, 68.44–72.54%, 17.87–26.79% and 41.65–54.55%. Minerals viz., calcium, phosphorus and iron ranged from 4.92–14.60 mg/100 g, 86.36–124.02 mg/100 g and 0.49–0.59, respectively.
