Temperature differentiation of genotypes for BV2 resistance in Pisum sativum






Phytopathology 56(1): 113-117

Temperature differentiation of genotypes for BV2 resistance in Pisum sativum

Symptom development in heterozygous (Mo mo) plants of Pisum sativum inoculated with certain strains of bean yellow mosaic viurs (BV2) can be manipulated by changing the temperature of the environment. Susceptible (Mo Mo) and resistant (mo mo) plants are not influenced by temperature. Mo mo plants incubated at 27[degree]C are completely susceptible and react like Mo Mo plants, irrespective of the normal strains of BV2 studied. Symptoms disappear on the new growth that develops when such plants are moved to 18[degree]C or lower are symptomless and simulate resistant plants until moved to a temperature of 27[degree]C, whereupon symptoms develop on the new growth of plants inoculated with most strains of BV2 but not all. Some common pea mosaic virus strains do not appear to be infectious to Mo mo plants when they are incubated at 18[degree]C or lower. Temperature differentiation of the heterozygote has practical application in breeding peas for resistance to BV2 and certain other diseases.
