Abstract:

This work aims to evaluate the nutritional components in wild germplasm resources of Agaricus bisporus,and to screen the germplasm with higher or special nutritional contents,for providing a scientific reference for the breeding of A. bisporus. The contents of protein,amino acid and fatty acid in 93 wild strains of A. bisporus were analyzed and evaluated using 3 main cultivars as controls,and then the germplasm resources with better nutrition were selected based on the nutrient components higher than the average ones. The results showed that the protein content of the wild germplasm of A. bisporus was 29.50-37.60 g/100g,the contents of essential amino acids were 4.51-8.89 g/100g,and the ratios of essential amino acids was 24.69%-40.59%. The linoleic acid content was 4 086.55-14 190.28 mg/kg,and the ratio of unsaturated fatty acids was 77.63%-87.47%. The average variation coefficient of amino acids was 21.05%,and that of linoleic acid was 22.93%. There was abundant variation in the contents of amino acids and fatty acids of 93 wild strains of A. bisporus. Based on the experimental results,14 germplasms with high and balanced nutrient were selected,which may provide parent materials for directive breeding of A. bisporus to improve quality.

Key words: edible mushroom, germplasm resources, protein, amino acid, fatty acid
