Conteúdo: | A large number of soybean cultivars with diverse genetic composition were evaluated by cooperators under a wide range of environmental conditions in the fifth International Soybean Variety Evaluation Experiment and in the second INTSOY/IITA Soybean Variety Evaluation Experiment during 1977. Thirty-six cultivars from maturity groups 0-ix including six new varieties, were divided into early, medium, and late mature trials. These cultivars provided a source of the latest improved germplasm to 185 sites in 70 countries. For the first time, a blend of three varieties was included in order to evaluated possible increased yield stability over planting single pure varieties. Furthermore, cooperators at 41 sites substituted an additional 60 locally developed cultivars to compare their performance against that of supplied entries. Useful data were returned from 101 sites. Yields from 1900-2800 kg/ha of good quality soybean grain were obtained consistently with better adapted cultivars in tropical and subtropical environments. The yield of some locally supplied cultivars matched that of the best INTSOY entries, but no local entries were significantly higher. The performance of the cultivar Davis was outstanding during 1977 as well as in multi-year summaries and in the stability analysis. Other cultivars near the top in yield included Jupiter, Forrest, Bossier, Improved Pelican, Mitchell, Ransom, Columbus and Williams. In the 1977 summaries, Davis ranked first in zones I and X and second in zones IV and VII. Yield rank was.
