Abstract:

In order to screen out the morel varieties suitable for cultivation in Xianju Area, Zhejiang Province, seven introduced morel varieties were compared and tested. The mushroom production, yield, agronomic traits and nutrients of seven morel cultivars were compared and analyzed. The results showed that the cap of Tileng was brown, the density of mushrooms was the densest, the shape of mushrooms was the smallest, and the fresh weight of a single mushroom was the smallest. The cap of Zidantou is grayish-brown and the mushroom shape is relatively uniform. The G8 cap is yellowish-brown in color, with thick flesh and a large mushroom shape. G10 did not grow. The 667 m² yield of Tileng, G5, Zidantou and G8 all exceeded 250 kg, and G5 produced the highest. The fruiting bodies of the six morel mushroom varieties were rich in protein and potassium, among which Zidantou had the highest protein content and Tileng had the lowest protein content. Glutamic acid content was the highest, followed by aspartic acid, and umami amino acids accounted for 24.64%-26.07% of the total amino acid content. The amino acid composition ratio analysis showed all were high-quality protein, and the G5 amino acid ratio is the most reasonable. Comprehensive analysis showed that the traits of G5, Zidantou and G8 performed excellently, and were more suitable for promotion and planting in Xianju and surrounding areas of Zhejiang.
