Abstract:
The present investigation was carried out to assess genetic potential of short duration sugarcane clones for yield and quality related characters. The Experimental materials consist of seven test clones viz., C 30027, C 30031, C 30035, C 29336, C 29373, C 29374, C 29442 and three standards (CoC (Sc) 24, TNAU Si 7 and CoC 671) in Advanced Yield Trial – Plant -I (AYT-I), Advanced Yield Trial Plant-II (AYT-II) and AYT- ratoon. Observations were recorded for tillers numbers per hectare (x1000/ha), millable cane numbers (x1000/ha), cane yield (t/ha), Brix (%), sucrose (%), Commercial Cane Sugar (%) and sugar yield (t/ha). The overall performance of the test clones for yield and quality traits in all the three evaluation trials (AYT I, AYT II and AYT ratoon) revealed that, the two clones (C 29442 and C 29374) were identified as better forming clones, since they showed higher cane yield, sucrose %, CCS percent, sugar yield, and number of millable canes per hectare over the best check variety of CoC (Sc) 24. Hence these two clones C 29442 and C 29374 are to be promoted for further evaluation trials for release as a new short duration sugarcane variety.
