Effect of Infection Stages on the Expression of Slow-leaf Rusting of Wheat Cultivars

By experiments of inoculating respectively mixed inoculum of Puccinia recmdi f. sp. trittici into field wheat at elongating,booting and flowering stages,the result showed that infection stages did not affect the expression of latent period,infection efficiency,sprorulation capacity,uredial size and yield components of wheat. The slow-leaf rusting of wheat cultivars expressed at all development stages of the hosts. Early or late occurence of wheat leaf rust had no effect on the expression of low-leaf rusting.
