Abstract:
Mandarins are highly preferred fruit crop in India where maximum genetic diversity is seen in Northeast part of the country. The present investigation was conducted during the year 2018-21 by collecting mandarin genotypes from different parts of Northeast India (Arunachal Pradesh, Assam, Meghalaya, Manipur, Mizoram, Nagaland, Tripura and Sikkim) along with three wild species to evaluate the genetic diversity using morphological markers Correlation studies showed that fruit weight had high significant positive correlation with yield, juice content, vitamin c, number of fruits per tree; shelf life have high positive significant correlation with pH only; number of fruits per tree have positive significant correlation with yield at both genotypic and phenotypic level which denotes the importance of selection of these traits for yield improvement. A direct selection of these traits will lead to simultaneous improvement of the above said characters and yield (kg/tree) in the mandarin breeding programme.
