Abstract

Fifteen pre release sugarcane clones were tested against sugarcane variety Co 6907 for their suitability to early planted conditions (December/January planting) under moisture stress/drought at Regional Agricultural Research Station, Anakapalle during 2018-19 and 2019-20. Sugarcane clones tolerance to moisture stress is need of the hour as sugarcane yields are drastically reducing due to moisture stress/drought. A field experiments were conducted with stress and non stress treatments for evaluation of sugarcane clones tolerance to soil moisture stress/drought. Among fifteen pre release clones tested sugarcane clones 2009A 107 (80.2 t/ha), 2006A 223 (79.50 t/ha), 2009A 252 (76.42 t/ha), 2011A 313 (72.64 t/ha) and 2011A 252 (71.48 t/ha) recorded higher cane yield over other clones tested. The standards 87A 298 and 83V 15 recorded a cane yield of 71.08 t/ha and 58.13 t/ha which are lower than the superior clones. These clones also recorded significantly low SLA which indicates more photo
