Grain sorghum international protein yield and quality trials; report No. 1
Purdue University-USAID"s first International Grain Sorghum Protein Yield and Quality Trials were establishd in 1972 and sent upon request to research workers located in Argentina, Brazil, Colombia, Guyana, Paraguay, Peru, Puerto Rico, Uruguay, Ethiopia, Egypt, Malawi, Nigeria, Uganda, Bangladesh, India, Indonesia, Israel, Korea, Pakistan, Philippines, Thailand and the U.S.A.

Abstract
The set contained 21 lines and three commercial grain sorghum hybrids (Sorghum bicolor (L.) Moench) selected on protein yield potential, diversity of phenotypes, origin and potential adaptability to diverse environmental conditions with a range in maturity and height. Mean yield over non-USA locations was 2627 kg/ha. The commercial hybrid, NK300, gave the highest yield at non-USA locations and 954036 was the highest yielding line. Highest yield reponse to high level fertility was obtained from the commercial hybrid NK300 and the line IS4225. Disease ratings indicated that resistance to Downy Mildew and head smut were present in several entries. Plant height and days to flower were reduced at locations nearest the equator. Twenty entries were selected by one or more cooperators for potential breeding purpose and/or further testing.
