Study of pre released sugarcane genotypes for agronomic traits and sugar yield

Abstract

Study pertaining to agronomic evaluation of ten pre released sugarcane genotypes was conducted at RS&RRS, Rudrur, PJTSAU, Telangana state during rabi 2016-17.Genotypes 2009 R 74, 2010 R 854, 2011 R 274, 2011 R 24, 97 R 401, 2011 R 1, 2011 R 305, 2011 R 327, 2011 R 47, and 2010 R 175 were studied for yield attributes, cane yield and sugar yield in comparison to popular variety 93 V 297. Experiment was conducted in randomized block design with genotypes as treatments replicated thrice. Genotypes 2011 R 274 recorded higher cane length (323.3 cm) cane girth (1.4 cm) single cane weight (2.0 kg) and higher number of total internodes (22nos) and was significantly superior over 93V297. Due to higher yield attributes significantly higher cane yield of 168 tons/ha was recorded with 2011 R 274, while 93V297 recorded cane yield of 101 tons/ha. Sucrose % and CCS yield was also superior with 2011 R 274 with 21.9% sucrose and 25.78 t/ha sugar yield.
