Melhoramento genético da cana-de-açúcar: VI. Ensaios de clones provenientes de hibridações realizadas em 1974, 1977, 1978 e 1979, avaliados na Região de Piracicaba (SP)
1992
Sugarcane clones obtained in crosses made in 1974, 1977, 1978 and 1979, were tested in two locations in the Piracicaba region. The clones and commercial varieties SP70-1143, IAC64-257, NA56-79 and CB41-76 were evaluated for agricultural and industrial traits in an average of three harvests. The clone IAC78-23 was obtained for cultivation in the region with high cane and sugar yields and adequate for use in middle and late harvest, and the IAC79-1011 with medium yield and high sugar content, indicated for inicial harvest. The clones IAC77-186, IAC78-54, IAC78-90 and IAC79-1149 showed medium yield and high sugar content, indicated for middle harvest in soils with high fertility.
