Allelic Relationship of Resistant Genes to Sunflower Downy Mildew Race 1 in Various Sunflower Inbred Lines
Muhammad Rahim

Abstract:
F2 and test crosses of the inbred lines with the recessive parent HA 821 were produced, tested for resistance reaction and allelic relationship of the genes; as with 3R : 1S in F; and IR : IS in test cross and 15R : 1 S in F2 and 3R : 1S in test cross with one gene and two genes segregation, respectively. Digenic and independent gene reaction of resistance was found in AMES 3235, PI 497250, and RHA 274, each having P11 and PI12 for resistance to SDM race 1, P12 and PI11 conferring resistance to race 2. DM-2 and PI 497938 each has PI12 and RHA 266 has only P11 to race. 1.
