Interpretive Summary: Cylindrocladium black rot (CBR) is an increasingly important disease in the North Carolina-Virginia peanut production region. Peanut varieties with improved resistance to this disease and improved agronomic characteristics will be beneficial to the peanut growers of this region. The Virginia-type cultivar, Perry, was developed in response to these needs. Perry has greater CBR resistance and higher yield than NC 12C, the cultivar it is likely to replace. Development of this cultivar provides growers of Virginia-type peanuts another option for high quality, high yield peanut production.
Technical Abstract: Perry (N93112C) is a virginia-type cultivar with alternate branching pattern characteristic of Arachis hypogaea ssp. hypogaea var. hypogaea, runner growth habit, large seeds (93g 100 seed-1) with pink testa, and resistance to CBR comparable to that of germplasm 'NC 3033.' Perry is an F4-derived line selected from cross X89140 made in 1989. The female parent was an F5-derived selection from a cross between NC 7 and Florigiant; the male parent was CBR-resistant line N90021. Single plants were selected in the F2 generation on the basis of large pod size, pod shape, and resistance in the presence of CBR in 1990. Selection was again made among and within F2:4 families on CBR-infested soil in 1991 and in 1992 for F4:5 families. Seed have been maintained in bulk since the last single-plant selection. Compared with NC 12C, Perry has similar SMK content (69%) and meat content (74%), but significantly fewer jumbo pods (30 vs. 56%), more fancy size pods (49 vs. 32%), fewer extra large kernels (46 vs. 53%), and higher pod yield (5306 vs. 4864 kg ha-1). Roasted samples were evaluated by a trained sensory panel under the direction of USDA personnel. Adjusted to common values of roast color and fruity attribute, the flavor of Perry was comparable to NC 12C in the sweet, bitter, and roasted peanut flavor attributes. The ratio of oleic to linoleic acid in the fatty acid profile was lower than NC 12C (1.59 vs. 1.83). Pods were significantly brighter in color than NC 12C (46.2 vs. 45.7 Hunter L for jumbo, 44.9 vs. 42.0 Hunter L for fancy pods), an important trait for peanuts sold as in-shell products.
