A field trial entitled performance of ginger (Zingiber officinale Rosc.) varieties on yield, quality, incidence of shoot borer and rhizome rot in Alfisol of Nagaland with nine genotypes. Among all genotypes, Bhaise emerged as the top performer across various growth parameters, including plant height (PH) (61.8 cm), number of tillers (NT) (7.6) and number of leaves (NL) (21), with the highest values recorded in John ginger. In terms of yield, Bhaise consistently produced the highest yields/clump (135.99 g), yield per plot (YPP) (2.04 kg), projected yield/ha (10.19 tha-1) and weight of mother rhizome (WMR) (19.67 g). Quality assessments revealed that Nadia recorded the highest oleoresin (OLR) content (9.06 %), PGS 102 the highest crude fiber (CF) content (7.29 %) and John ginger the highest essential oil content (OC) (2.39 %). Mahima was found to have the highest dry recovery (RCV) percentage (25.7 %). Mahima showed the least susceptibility to rhizome rot and shoot borer among these genotypes. Genotypic correlation analysis revealed strong positive associations among PH, NT and yield traits. Yield per clump (YPC) showed a high positive correlation with YPP and projected yield per hectare (PYH). Principal component analysis (PCA) extracted five components, which cumulatively explained 93.73 % of the total variability. The first two components, Principal Component 1 (PC1) and PC2, accounted for 61.6 % of the variance. PC1 (42.12 %) was associated with PH, NT and yield attributes forming a yield vigour axis, while PC2 (19.54 %) represented quality traits such as oil content (OC). The PCA biplot grouped Bhaise, Gorubathani and Nadia on the positive side of PC1, whereas Mahima, John Ginger and Karbi Ginger clustered along PC2. These findings highlight the potential of high-yielding, high-quality lines for developing improved ginger cultivars under the Alfisol conditions of Nagaland.
