Inter and intra stage correlation was also studied in preselected population across organic and integrated environments. The GCV and PCV for germination (%), total shoots (TS), cane formed shoots (CFS), and green top yield (GTY) were higher, whereas moderate variability was observed for internodal length (IL), single cane weight (SCW), number of millable cane (NMC), cane girth (CG), cane yield and commercial cane sugar yield (CCSY). The association studies revealed that viz., NMC, cane height, IL, CFS, SCW and CCSY were positively associated with cane yield. The repeatability studies indicates that traits viz., germination (%), TS, NMC, SCW, cane height, CCS yield, HR brix and sucrose per cent at 10th month were comparatively highly significant with moderate to higher heritability values indicating these traits as more dependable as selection criteria. For cane, sugar and jaggery yield and quality parameters, top 17 genotypes showing superiority under integrated and organic environment. Among them four genotypes viz., SNK 10286, SNK 10241, SNK 10134 and SNK 10132 found highly productive under integrated environment. The genotypes viz., SNK 10162, SNK 10241, SNK 10283 and SNK 10286 were recorded significantly superior under organic environment. Across the environments the genotypes viz., SNK 10286 and SNK 10232 were found most promising, as they recorded higher jaggery productivity and acceptability index respectively, over best jaggery standard Co 92005. The organoleptic features and overall acceptability index of jaggery under organic environment were superior over integrated.EnglishThesis
