Inheritance of white rust in newly developed resistant line of Brassica Juncea from local germplasm

Abstract: Brassicas are important source of vegetable oils in all over the world but various abiotic and biotic stresses caused huge losses to yield out of which white rust occurred 50 to 89.8 %. The cultivation of disease resistant varieties seems to be the most practical and affordable means to combat against this disease. In the present study, new white rust resistant line of Indian mustard PWR 15-8 was screened out from local germplasm collected from hills of Uttarakhand (India). The inheritance of white rust in PWR-15-8 was deciphered by crossing it with two agronomically superior susceptible varieties. All F1s were found resistant and F2 gave segregation of 3:1 for resistant and susceptible plants indicating thereby that the resistance is monotonically dominant over susceptibility. As expected the observations on back crosses of F1s with their respective susceptible strains (BC2) showed segregation of 1: 1, while all BC1 plants were resistant.
