Abstract:

In this paper, the study of the peanut fruit yield, peanut groups and the major nutrients accumulation of quality-related were taken in the new peanut variety ‘Fuhua 4’ by the national testing standards. The results showed that fruit yield of peanut increased with the day’s growth of the needle under. Fruit seeds had 15.1% crude fat content fatty acids. C18:1n9c, C18:2n6c and C16:0 were the highest proportion, and C18:1n9c accounted for 45.8%, C18:2n6c accounted for 31.4%, C16:0 accounted for 13.0% were 90.2% of crude fat in the maturity period. The growth curve of crude fat was a parabola. Accumulation of fatty acid composition had three types. The O/L value reached the maximum value of 1.46 to the maturity. Protein content of fruit seeds had wave-type changes during the pod dry matter accumulation process. Trend of amino acids was consistent with the protein. The peak had emerged about the next needle 35 d. Protein content of 8.85 g/100 g and amino acid content was 7.46% in the maturity. 17 amino acids were detected, with the highest content of glutamic acid. There were three changes types of curves of amino acid. The trend of sugar, reducing sugar and total sugar of the peanuts were high to low and then high with the accumulation of dry matter. The contents of sugar, re ucing and total sugar were 2.2 g/100 g、0.1 g/100 g and 2.42 g/100 g respectively in mature period. The experimental results showed that ‘Fuhua 4’ fruit yield and the main nutrient content of groups’ quality reached the highest or higher value in maturity, so to obtain high yield of peanut yield and good quality ‘Fuhua 4’ should be taken in maturity.
