Multivariate analysis of ginger (Zingiber officinale Rosc.) germplasm of North Eastern India

Published on Jun 01, 2018 03:51 AM

Eighty two ginger (Zigiber officinale Roc.) accessions
collected from North-Eastern region of India were subjected
to study genetic diversity considering 12 quantitative and
7 qualitative characters using multivariate analysis.
Considerable variation was recorded among ginger
accessions for all the morphological traits studied. Yield
showed significant but not of high degree correlation with
eight characters studied. Most of the qualitative characters
were found to be non-significantly correlated among
themselves and with quantitative characters. Principal
component analysis based on different characteristics
grouped the germplasm into eight clusters. Seven cultivars
found to yield consistently well under organic conditions.
Considerable variation was observed among the clones
related to internal colour of rhizome and pungency.
