A Primary Report on Applying Extract from Diseased Grains of Wheat Scab to the ldentification of Scab-resistance

Seeds of eight wheat varieties with different scab-resistances were soaked in the extracting so-lution from diseased grains of wheat scab(poison solution)for germination. the results showed that the susceptibilities of wheat seeds to the scab poison solution varied significantly with different varieties. The resitant varieties have strong standing capacity in the poison solution and show a high germinating rate;whreas,the sensitive varieties show low germinating rate.The above results are identical to the identify-ing data on the scab resistances of different wheat varieties from multi-site field test for years.
