Flooding tolerance of sugarcane genotypes under recurring floods in plant and ratoon crops

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

The goal of this research was to evaluate the flooding tolerance of sugarcane genotypes under recurring floods of both plant and ratoon canes. Control and recurring flood conditions were compared using 10 sugarcane genotypes. As a result of the flooding, cane height increased and tillering decreased. Flooding reduced cane yield and commercial cane sugar (CCS) yield, as well as the percentage of polarization (POL), purity, and CCS in sugarcane juice. Sugarcane flood tolerance varied by genotype, with KPS01-4-29 and SP94-2-483 having the highest flooding tolerance index and KK07-037, K95-84, and KK07-599 having the highest yield under flooded conditions. Furthermore, under flooded conditions, a relationship between yield traits, cane height, and cane number was observed in sugarcane (r = 0.45* to 0.92**). As a result of our research, flood-tolerant sugarcane genotypes could be selected. Sugarcane genotype selection for flooding tolerance could include cane height and cane number as indirect traits.
