Abstract/Description: | Co 12009 is a high yielding and midlate maturing variety identified through hybridization of [ (Co 7201 x ( Co 62174 x SES 91) x Co 88037 ) ] x Co 62198 of which SES 91 clone is a genetic base involving S. spontaneum. This is a third back cross of F1 hybrid involving Co 62174 and SES 91 and back crossed with three commercial hybrids viz., Co 7201, Co 88037 and Co 62198 at three stages of nobilisation .This clone showed improved vigour and high sucrose in the different clonal stages. The entry performed well in AICRP trials conducted across the States of Peninsular zone for cane yield, sugar yield, sucrose % and pol % cane with an overall mean of 119.65 t/ha of cane yield, 17.31 t/ha of commercial Cane Sugar, 19.91 % of juice sucrose and 15.47 % of Pol in cane at 360 days of harvest in comparison with three zonal checks viz., Co 86032 (Midlate), CoC 671 (Early) and CoSnk 05103 (Early). The variety registered an overall improvement of 10.40 %, 18.08 % and 15.32 % over the best midlate standard Co 86032 and early standards viz., CoC 671 and CoSnk 05103 respectively for sugar yield. This high yielding variety recorded an improvement of 9.03 %, 7.92 %, and 23.42 % in comparison with the standards Co 86032 (109.73 t/ha), CoSnk 05103 (110.85 t/ha), and CoC 671 (96.93 t/ha) respectively. Co 12009 recorded 19.91 sucrose % which was 1.80 and 6.99 percent increase over the midlate standard Co 86032 and early standard CoSnk 05103 respectively.Co 12009 showed 1.97 per cent improvement in Pol % in cane over the other qualifying variety CoM 12085 (15.17 %). It is an excellent ratooner with an improvement of 13.70 % and 10.43 % for sugar and cane yield respectively over the midlate standard Co 86032. The variety combines resistance to red rot and wide adaptability in varied environments. |
