Abstract

Growth and physiological attributes and sugar quality parameters are considered key criteria for screening sugarcane cultivars for salt tolerance. Maximum cane growth and yield were found in a positive check (‘K88-92’) as well as in cv. ‘(A3)AE1-18’ when subjected to salt affected soil. Percent reduction in Fv/Fm, quantum efficiency of PSII (ΦPSII) and water use efficiency (WUE) due to salt stress was considerably low in ‘K88-92’, ‘(A3)AE1-18’ and ‘KK3’ which was associated with very low salt-induced reduction in net photosynthetic rate and growth characters such as shoot length, number of internodes, and internodal length as well as yield traits. In addition, brix, polarlization, fiber, purity and commercial cane sugar (CCS) in ‘(A18)AE2-15’ and ‘(A3)AE1-18’ were well maintained under saline stress. By subjecting the data for various physiological, growth, yield and sugar quality parameters to the Ward’s cluster analysis ‘K88-92’ (positive check), ‘(A3)AE1-18’ and ‘KK3’ were identified as salt tolerant, whereas ‘(A11)AE1-114’ and ‘K97-32’ as salt sensitive.
