    Pod Breakdown Resistance in Peanuts¹

    Authors: , ,


During 19 6973, 13 commonly grown Virginia-type peanut (Arachis hypogaea L.) cultivars, 15 plant introductions. and two breeding lines were evaluated under field conditions for resistance to the pod breakdown fungi Pythium myriotylum and Rhizoctonia solani. Four cultivars--Early Runner. Florunner, Florigiant, and NC 17--having related pedigrees were consistently more resistant to infection by these two fungi. P.I. 341880 and P.I. 341885 and Florida breeding line F439166 showed similar resistance to infection. Cultivars most susceptible to pod breakdown were NC 5, Va. 56R, Ga. 11920 and Va. 72R. P.I. 343410 and a selection from P.I. 319178 were extremely susceptible to pod breakdown. Resistance to pod breakdown seems to have been derived from a cross between a small, white-seeded Spanish-type peanut and Dixie Giant, a large-seeded Virginia-type peanut. All resistant cultivars are related to this cross, whereas the susceptible cultivars lack these parental types in the pedigrees.
