12 IAC甘蔗无性系来自1982年进行的杂交，从1990年至1994年进行了评估，在三个网站的里贝劳Preto/地区，在Rhodic Hapuludox土壤。使用完全随机区组设计建立实验试验，每个位点重复六次。在四个生长季中，测定了甘蔗和蔗糖产量（t.ha-1）、茎含糖率、茎纤维含量和茎数。IAC 82 -2045的产量潜力显著高于对照品种和其它试验品种，含糖量中等，适宜于中、晚季采收。遗传参数估计显示出显着的基因型x环境的相互作用，主要是甘蔗和糖产量潜力。
Twelve IAC sugar cane clones derived from crossings carried out in 1982, were evaluated from 1990 to 1994, at three sites of the Ribeirao Preto/ region, in Rhodic Hapludox soils. Experimental trials were set up using a complete randomized blocks design, with six replications per site. Cane and sugar yield (t.ha-1), stalk sugar content, stalk fiber content and stalk number were estimated in all four growing seasons. IAC82-2045 the clone significantly outperformed control varieties and other experimental clones regarding yield potential, revealing intermediate sugar content and being proper for mid to late season harversting. Genetic parameter estimates have shown significant genotype x environment interactions, mostly for cane and sugar yield potentials.
