Result of evaluating the sugarcane collection for selection of high performance and diseases resistant varieties adapted to northcentral area
Sugarcane is one of important industrial crop for northcenter of country. Nevertheless there are.somes difficulties in sugarcane production like as: Set of variety is quickly degenerated,almost these varieties are infected by pest and diseases, with low performance(55-57 tons/ha). So several researchs for sugarcane varietal improvment had been carried and obtained followng results. In the observation experiment of sugarcane collection with 58 accesments had been identified about 20 elite varieties (K95-84,Suphanburi7, K95-156, K90-77, K88-92,K88-65, K88-200, VĐ93-159; Rb72-454, VĐ00236; ROC10; ROC28; Philippin 85-86; Philippin 88-83; Phuc nong; ROC16.ROC22..). These varieties were took part in avarietal comparaison trial and selected 5 promissing varieties (Suphanburi7, ROC28; ROC26; Philippin 88-.ROC22) with high yielding and sugar content,are adapted to ecological condition of northcentral area. Among of these promising varieties ROC28 and Philipin88-83 having yield of.90 tons per ha, high sugar content(11CCS) and resistant to pest and diseases. They are propagating for carrying out test experiment in big scale.
