Rapid Assessment of Rind Hardness in Sugarcane and Its Association with Biochemical Traits

Rind hardness in sugarcane plays a major role lodging resistance, and internode borer resistance,screening of for rind is essential reducing yield loss. In order to identify the suitability soil penetrometer rapid measurement, testing was carried out two clones different variability viz., Co 13003 (hard type) 14002 (soft type). The investigation by three methods pendulum type impact test rig, texture analyzer,and theresults revealed that thehard clone observed with significantly greater hardness. Significant correlation between trait among method determination easy rapid. Two-way hierarchical cluster analysis studied biochemical traits has better classification hard-rinded soft-rind clones. recorded as least susceptible borers high (>200 psi), along fibre. NG 77 hard also lignin compared soft Gungera.
