SCREENING AND COMPARISON OF SUGARCANE GENOTYPES FOR CANE AND SUGAR YIELD TRAITS
Abstract
The trials were conducted during autumn sugarcane sowing season (August-September) for two consecutive years (2014-15, and 2015-16) to screen out the most promising sugarcane lines in a three replicated RCBD (Factorial). Eight sugarcane lines Th-1201, Th-1205, Th-1206, Th-1208, Th1210, Th-1211, Th-1223, and Th-1238 were tested, and their overall performance concerning cane yield, and sugar content related traits was compared with commercial check Th-10. The results revealed that cane yield was significantly highest (P<0.05) in new variety Th-1201 (213.92 t ha-1), followed by varieties Th-1238 (195.23 t ha-1), Th-10 (195.23 t ha-1), Th-1205 (193.54 t ha-1), Th-1211 (178.26 t ha-1), Th-1208 (143.46 t ha-1), Th-1206 (136.67 t ha-1), Th-1223 (115.44 t ha-1). New promising variety Th-1201 surpassed commercial check-in cane yield, while varieties Th-1238 and Th1205 were at par with the commercial check (Th-10) for cane yield ha-1. In case of CCS, it was significantly higher in sugarcane variety Th-1210 (14.45 t ha-1) as compared to varieties Th-1201 (14.31 t ha-1), Th-1206 (13.90 t ha-1), Th-10 (13.73 t ha-1
), Th-1238 (13.40 t ha-1), and Th-1223 (13.38 t ha-1). In CCS, the varieties Th-1210, Th-1201, and Th-1206 exceeded commercial check (Th-10), while the rest of the varieties were slightly inferior in CCS to commercial check.
