Online published on 26 December, 2023. Abstract Black pepper, the king of spices, is grown for its dry berries. Genetic variation and relationship between yield and yield linked characters were studied in six black pepper genotypes. Highly significant differences for all the characters studied were observed. Maximum GCV and PCV were noted for dry berry yield, number of spikes plant−1 and fresh berry yield. High heritability and genetic advance over mean of these traits indicate additive gene effect in the expression of these characters. Dry berry yield plant−1 had a very strong correlation with vine column height, number of branches vine−1, spike length, number of berries spike−1, fresh berry yield and dry recovery at both phenotypic and genotypic levels. During path analysis, fresh berry weight showed high positive direct effect on dry berry weight. Number of branches vine−1, vine column height, spike length, number of berries spike−1 and dry recovery had indirect positive effects on dry berry weight. Panniyur 5 was found superior in morphological, yield and yield related characters among the different genotypes. Kumpukkal was found promising for various economically significant features among the genotypes from farmer's fields. Pepper Thekken exhibited branching habit of spikes compared to other genotypes.
