0	PI 693344	'A680'	Zea mays L. subsp. mays	Minnesota, United States	NC7		1996	DEVELOPED	05/1987				Breeding material	A680 is an early version of B73 developed by an early by late procedure, backcrossing to B73 three times. Silking is about 3-4 days earlier than B73. It combines well with Lancaster germplasm and some early B14 types. Out-performs B73 by 30% with about 5% less moisture. High kernel row with small seed. Lodging similar to B73. Adapted to South-central and North-central Minneosta. (University of Minnesota Agriculture Experiment Station Release of Corn Inbred Lines, May 1987)	1535466	PI 693344
1	PI 587143	'A682'	Zea mays L. subsp. mays	Minnesota, United States	NC7		1993	DEVELOPED	05/1987				Breeding material	A682 and A683, early versions of Mo17, were developed with two backcrosses to Mo17 using early synthetic, AS-D, as the source of earliness. In Minnesota, these lines silk a week earlier than Mo17 and outyield Mo17 by7 more than 50%. Although the seed is still large, these inbreds grade out with more flat kernels compared to Mo17. Pollen production is fair to good. Lodging resistance of A683 is superior to A682 as a line and in hybrids. Adapted to South-central and North-central Minneosta.

9	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).

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.

67	Ames 23505	'A683'	Zea mays L. subsp. mays	Minnesota, United States	NC7		1996	DEVELOPED	05/1987				Breeding material	A682 and A683, early versions of Mo17, were developed with two backcrosses to Mo17 using early synthetic, AS-D, as the source of earliness. In Minnesota, these lines silk a week earlier than Mo17 and outyield Mo17 by7 more than 50%. Although the seed is still large, these inbreds grade out with more flat kernels compared to Mo17. Pollen production is fair to good. Lodging resistance of A683 is superior to A682 as a line and in hybrids. Adapted to South-central and North-central Minneosta.
