Abstract
A source of immunity to apple mildew, Podosphaera leucotricha (Ell.&Ev.) Salm., derived from a Malus species, when crossed with susceptible cultivars, conferred immunity to 50% of its progeny in greenhouse and field tests. Reciprocal crosses indicated a nuclear gene. A greenhouse method for large-scale screening is described.
Abstract
‘Williams’ Pride’ is an early-maturing, attractive, dark red apple (Malus × domestica Borkh.) with excellent fruit quality and field immunity to apple scab incited by Venturia inaequalis (Cke.) Wint. The fruit is of medium to large size and matures with the very earliest known commercial red cultivars in the midwestern United States. It ripens 1 week after ‘Lodi’ and 7.5 to 8 weeks before ‘Delicious’. ‘Williams’ Pride’ is released as a potential commercial cultivar for use as a summer dessert apple. The apple is named in honor of Edwin B. Williams, Emeritus Professor and long time leader of the disease-resistant apple breeding program at Purdue Univ.
