The new method of relating wheat genotypes seedlings to Puccinia tritici resistance characters in greenhouse with maximal infection intensity in field

The former method for estimating characters of resistance level to Puccinia triticina at seedling stage in greenhouse was of low capacity according to number of simultaneous tested wheat genotypes because of inoculation in settling tower, three days of successive pustule counting on each plant and time spent in data processing. The aim was to change all these limiting factors and achieve at least the similar correlation of data processed throw new formula with maximal infection intensities in field. The resistance characters values of seedlings were achieved at approximate 20 °C in greenhouse during the winter period (temperature rising below 24 °C increase the leaf rust development)
