Abstract
Description
【Technical field】
[0001] The invention relates to the construction of the AFLP fingerprint of the resistance of Phytophthora soybean to metalaxyl. 【Background technique】
[0002] Phytophthorasojae (Phytophthorasojae) can cause Phytophthora sojae root rot, which is extremely harmful in soybean production. Soybean blight has become a prominent problem in China's soybean production and has brought serious economic losses to my country's soybean production.
[0003] Phytophthora soybean is a soil-borne fungus, but the pathogen is highly parasitic and cannot compete for growth and colonization on soil particles, and oospores can survive for many years in plant residues and soil. Phytophthora sojae on lima beans, corn flour, V 8 It grows faster on medium such as juice, and the colonies are uniform and the edges are neat. Mycelium is 3-9 μm wide, easy to curl; mycelium is coral-like, with nearly right-angled branches, slightly constricted at the base of branches, and septa are f...
