Analyzing the performance of sugarcane (Saccharum spp) clones under abiotic stresses using ANOM as a tool

Thirty sugarcane (Saccharum spp) clones were evaluated for stalk yield, CCS yield and sucrose% in two plant and one ratoon crops under four environmental conditions, viz. water stress, waterlogging, saline and normal. The statistical tool ANOM and GGE-Biplot was employed to quantify the performance of clones across and within environments. Stalk yield decreased by 20.41% under water stress, 14.07% under waterlogging and 5.45% in saline conditions. The CCS yield decreased to the tune of 20.93% under water stress, 15.28% under waterlogging and 5.65% in saline conditions. Irrespective of abiotic stresses, plant crops recorded 25.25% higher stalk yield and 29.31% higher CCS yield than the ratoon crop. Based on ANOM tools, five top ranking clones for stalk yield (Co 97016, ISH 148, CoLk 8102, Co 98016 and Co 97015) and CCS yield (Co 97016, Co 98014, CoLk 8102, Co 97015 and Co 98016) were identified which could be used as commercial varieties for planting under abiotic stresses or as parents in abiotic stresses resistance breeding programmes.
