COMPARATIVE SUGARCANE CLONAL STUDIES AT ADVANCE NURSERY SELECTION STAGE

Abstract

Comparative performance of 251 clones against standard variety CP77-400 was conducted in a non-replicated trial, having net plot size measuring 2.4 x 5 m. Keeping in view the desirable characters, 133 clones were selected and promoted to preliminary varietal trial while 47% clones were rejected due to undesirable characters. In general 2.39%, 5.58%, 11.15%, 4.78%, 2.78%, 5.58%, 5.18%, 2.79% and 6.77% clones were rejected because of poor growth, pithiness, low brix, aerial roots, cracks, sprouts, disease susceptibility, insect pest infestation and lodging, respectively.
