The contribution of S. robustum in the development of cultivated varieties of sugarcane is very less compared to other wild species of sugarcane. Some of the popular varieties of Hawaii were immensely benefited from this wild species but only the Port Moresby type could find a place in the ancestry. In India also, some of the recent Co canes have the improved clones of S. robustum in their pedigree. This paper discusses the characterization of interspecific progenies generated from polycross on two clones S. robustum forma sanguineum (red fleshed S. robustum) and their potential in the crop improvement programme of sugarcane. This is the first report of utilization of the red fleshed S. robustum clones in breeding programme of sugarcane. The progenies developed possess high variability for morphological and yield traits with considerable improvement over the S. robustum parents. The variability generated will be of utmost importance in crop improvement programme of sugarcane as the world gene bank holds only very limited variability for this group of plants (2n = 60) which are characterized by gigantic growth and red coloured flesh.

鲁棒链球菌无性系的杂交后代的特征 血红素

与其他野生甘蔗品种相比，强壮链球菌在甘蔗栽培品种开发中的贡献要小得多。夏威夷的一些受欢迎的品种从这种野生物种中受益匪浅，但只有莫尔斯比港类型可以在祖先找到一席之地。同样在印度，一些最近的甘蔗在其血统中具有改良的强壮链球菌克隆。本文讨论从polycross上的两个克隆间产生的后代的表征S.粗壮备考sanguineum（红肉S.粗壮）以及它们在甘蔗作物改良方案的潜力。这是首次使用红色肉豆蔻甘蔗育种程序中克隆。发育的后代在形态和产量性状上具有很高的变异性，与强壮链球菌的亲本相比有很大的提高。产生的变异性在甘蔗的作物改良计划中将是最重要的，因为世界基因库对这组具有 巨大生长和红色果肉特征的植物（2 n = 60）仅具有非常有限的变异性。
