Resistance mechanisms and selection for resistance in sugarcane to sugarcane weevil borer : SRDC final report BSS15

Abstract

This project primarily sought to determine resistance mechanisms and selection mechanisms for resistance in sugarcane to SWB (Sugarcane weevil borer). As such it addressed the SRDC strategies of developing more productive cultivars by increasing clonal resistance to insect pests, and of developing resource management practices that ensure sustainable productivity through the expanded use of GCTB. From prior assessment of SWB infestation in parental clones at BSES Meringa and clones in advanced selection trials in the crop-improvement program based on on BSES Meringa, as well as reference to existing literature, reaction to SWB infestation obviously is a multifaceted trait that may encompass many individual plant traits. This research was based on a hypothesis that attempted to cover as many of these traits and their possible interaction with the insect.
