0PI 638551DE3Zea mays L. subsp. mays Delaware, United StatesNC7KERNELS2005DEVELOPED04/2002Breeding materialA vigorous silker with good flowering synchrony. Has about the same number of days to pollen shed as B73Ht and Mo17Ht, but silks one and a half days earlier than B73Ht and four days earlier than Mo17Ht. It has the agravitropic phenotype for the primary root. Is shorter than B73Ht and also has lower ear placement. Ears have 14-16 kernel rows and white cob color. Pollen production and anthesis duration are excellent. Has intermediate resistance to first and second-generation European corn borer and gray leaf spot . Has good yield in hybrid performance with Stiff Stalk testers.1671772PI 638551

Is taller than B73Ht in plant height but similar in ear placement. Has ears with 18 kernel rows and red cob color, and has excellent grain quality. Has high leaf feeding resistance and intermediate resistance to second-generation European corn borer . It is susceptible to gray leaf spot . Has good yield in hybrid performance with non-Stiff Stalk testers.1671774PI 638553
