Screening of the Early Maturing Sugarcane Clones for high Cane Yield & Brix content in First Clonal Generation

During 2023-24 at Research Farm, RPCAU, Pusa, Samastipur, Bihar sixty clones from six different bi-parental crosses along with three checks were planted in Augmented Design to study variability among the clones for productive traits viz germination percentage at 45 days after planting, number of tillers at 120 days after planting, Stalk height at harvest, cane diameter at harvest, single cane weight at harvest, number of millable canes at harvest, brix value in October, November and December and cane yield. The analysis of variance indicated a significant difference among the entries for all parameters in the first clonal generation. The bi-parental cross, Co 58189 × CoSe 01434 showed maximum variation for the five character viz, number of tillers at 120 DAP, number of millable canes, brix value at middle of Oct., Nov., Dec. & stalk height followed by BO 91× Co 62198, evidenced maximum variation in cane diameter and single cane weight and the cross BO91× Co775 exhibited the highest degree of variance in cane yield. Ten clones, namely CoX 23091, CoX 23094, CoX 23099, CoX 23100, CoX 23123, CoX 23112, CoX 23125, CoX 23126, CoX 23233 and CoX 23234 were effectively selected from the first clonal generation bearing high brix coupled with high cane yield and they can be utilised for further varietal development programme.
