Abstract:
Background and Objective: Plant breeders are interested in rapid screening among large populations, particularly in the early stages of crop growth. However, information about applying hydroponic media on sugarcane genotype screening is still lacking. The question is arisen whether it will be feasible at an early growth stage is interested to investigate. This study was aimed to determine the most efficient screening time for phenotyping sugarcane root in hydroponics. Materials and Methods: Six sugarcane genotypes differing in root performance were evaluated under both hydroponics and field conditions. The genotypes were subjected to RCBD with three replications and observed at one, two and three Months After Planting (MAP) in hydroponics, whereas RCBD with four replications at three MAP in field trials. Data were recorded on growth stage, physiological and root attributes. Results: In one, two and three months showed positive correlation between root traits. The relationship between root length in soil and hydroponic at two MAP was existed on depth of 0-20 and 20-40 cm and at three MAP correlated with depth of 0-20, 20-40 and 40-60 cm. Both stem and root dry weight can be assigned as selection criteria to root length, root surface area and root volume of sugarcane in two and three MAP, but it was not found relative with SPAD Chlorophyll Meter Reading (SCMR) and Chlorophyll Fluorescence (CF) under hydroponic condition. Conclusion: This result indicated that hydroponic system can be applied in sugarcane, root screening as early as from two MAP to three MAP.
