Аспен Турсынгалиевич Орынбаев The stem resistance of cabbage to black rot prevents the systemic spreading of the pathogen Xanthomonas campestris pv. campestris localized in the infected leaves. In 2016-2018, the authors conducted a study to search for effective methods for the stem resistance detection and evaluation in plant breeding material and analyze the resistance inheritance in white cabbage samples. It has been shown that two methods - that of leaf sinus pricking and the excised cotyledons assay can be used to assess this type of resistance. However, the second method is more efficient for mass screening of breeding material reaction. It has been revealed that the stem resistance in the line Tsrl is race-specific and controlled by a single recessive gene. The second recessive gene controls the leaf hydatode resistance. This line has shown immunity to races 0.1, and 3 under all inoculation methods, and proved to be susceptible to race 4 of Xanthomonas campestris pv. campestris.
