Abstract:

Sugarcane is a major agro-industrial crop in India. The fibre content in sugarcane is gaining importance as fuel for co-generation of electricity. Hence, the present study was proposed to genetically characterize and identify suitable clones for co-generation with high yielding, optimum sucrose per cent, erect, non-lodging and good ratooning ability characters. Genetic analysis of 10 sugarcane hybrids was carried out using STMS primers. Out of 110 markers amplified, 77.27 % were polymorphic with an average of 8.5 polymorphic products per STMS primer. Similarity coefficient value of 0.79 and 0.48 was detected with closely and distantly related hybrids respectively. The average genetic similarity among the hybrids was ~78.6%. These results indicated the existence of moderate level of genetic diversity among these high biomass hybrids. Evaluation trial in replicated randomized block design including five early and five mid late clones was conducted at Regional Agricultural Research Station (RARS), Anakapalle during 2007 to 2010. Early clones viz., CoA 03081 (123.0 t/ha and 14.93 t/ha), CoA 02081 (122.0 t/ha and 14.78 t/ha) and CoA 07321 (118.7 t/ha and 14.10 t/ha) were significantly superior for cane and CCS yields than the best standard Co 7508 (104.0 t/ha and 13.34 t/ha). Midlate clones viz., CoA 07322 (137.0 t/ha and 17.12 t/ha) and CoA 02082 (132.0 t/ha and 17.00 t/ha) were significantly superior over the standard CoV 92102 (125.0 t/ha and 16.95 t/ha) for cane and CCS yields. The fibre content of the early and midlate clones ranged from 18.67 (CoA 02081) to 22.50 (CoA 03081) and 20.17 (CoA 07322) to 23.00 (CoA 03082), respectively. These elite clones recorded resistant reaction to red rot disease. The results revealed the potential of these clones suitable for co-generation of power with high yielding, high fibre content, optimum sucrose per cent and good ratooning ability.
