Abstract
Genetics components analysis exhibited over dominance for all the characters in both the generations except plant height which showed partial dominance in F1 and complete dominance in F2. The value of genetic component (F ˆ ) were found positive for all the characters in both generations except number of primary branches and plant height in both the generations. The positive and significant values of F ˆ indicated that the dominant genes were more frequent than recessive ones in the parents for concerned character. The correlation coefficient (r) between parental order of dominance and parental measurement was not found to be negative for any character.
India plays a major role in global oil seeds and vegetable oil economy contributing about 16% of world’s oil seed crop area, 7% world’s oil seed production and 6.7% vegetable oil production. Oil seed crop being the second most important determinant of agricultural economy next after early sharing about 15% of the country’s gross cropped area and accounting for nearly 3% of the gross national product and 10% of the value of all agricultural products and 1 million farmers involved in oil seed cultivation and processing , respectively. There is a severe shortage of edible oil in the country. The per capita availability of edible oil is only 11 g/day as against the normal requirement of 30 g/day. Thus the availability of energy through oil is world limited. The oil obtained from different forms of rapeseed mustard show slight variation in percentage of oil. The oil content varied from 37 to 49 per cent. Mustard oil contains about 70% mono unsaturated fatty acid (MUFA) of which 42% is erusic acid and 12% oleic acid. The seed and oil are used as condiments in the preparation of pickle and for flavour carrying out vegetables. The oil is utilized for human consumption throughout northern India in cooking and frying purposes. The oil cake is used as a cattle feed and manure. Green stems and leaves are a good source of green fodder for cattle.
