20	PI 550467	'B37'	Zea mays L. subsp. mays	Iowa, United States	NC7		1971	DEVELOPED			Breeding material	Plant vigorous. Seed yield good. Pollen production poor. Root and stalk strength moderate. Maturity is AES800. Some resistance to northern corn leaf blight (Helminthosporium turcicum). During its era of heavy usage the line contributed high yield to single-cross hybrids particularly when grown at moderately high plant densites. In an ASTA 1975 survey reported in The Second Meeting of the Interregional Corn Conference, February 9-12, 1976 in Cincinnati, Ohio; almost 66 million kg (~145 million pounds) of parent seed were used in 1974 for hybrid production for 1975 planting. This represented 6.8% of the total 1975 requirement.	1445403	PI 550467
