Correlation and path coefficient analysis in ber genotypes for yield and yield contributing traits

摘要

In India, there is rich genetic diversity in both cultivated as well as their wild relatives of various fruit crops including ber (Ziziphus mauritiana Lamk.) which is the most popular fruit of arid regions. The northern India is unique due to their typical climatic conditions. These conditions are congenial for the cultivation of various fruit crops. A number of genotypes of ber have been planted in Haryana, Rajasthan, Gujarat and Punjab regions. An unsystematic introduction and indiscriminate multiplication from various sources and types of base material in ber have resulted in a lot of variation in the existing population. Knowledge of association between yield and yield contributing characters of crop is of paramount importance in selection and hybridization programme. The present study; was, therefore, undertaken to know the casual components of relationship among various traits by using correlation and path coefficient analysis.
