“…In a study, fty accessions were grouped based on morphological similarity. The hierarchical cluster analysis showed that 35 out of 50 black pepper accessions clustered in a single group, which indicated the absence of signi cant morphological divergence among them (Prakash et al 2020).…”

Black pepper landraces and local cultivars maintained by farmers over centuries in different agroclimatic conditions in Kerala are useful for utilizing valuable allelic diversity in breeding programs. A survey conducted in the black pepper growing regions of Kerala identified 21 genotypes with superior yield and distinct characters. Observation of qualitative morphological traits revealed moderate variability among the black pepper genotypes. The dendrogram constructed using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) method grouped 21 genotypes into 15 clusters at 73% genetic similarity and the similarity coefficient ranged between 0.47 and 0.81. Biochemical evaluation revealed considerable variations in their piperine (3.0–5.6%), essential oil (3.0–5.6%) and oleoresin (6.3–13.2%) contents. The principal component analysis could describe the evaluated traits as nine main and independent components, which were able to justify 86.59% of the total variance. Eigenvalues indicated that a majority of yield-related traits, viz., leaf petiole length, leaf length, leaf width, fresh spike yield, fresh berry yield and dry yield and physiological traits such as leaf thickness, relative water content and epicuticular wax, contributed to the total diversity of the black pepper germplasms. Based on the present investigation, genotypes such as G16, G15, G21, G1, G5 and G4 with considerable genetic divergence and desired qualities can be employed as good candidates in breeding programs.

“…Twenty black pepper accessions selected based on yield (>400g dried berries), field tolerance to pollu beetle and phytophthora foot rot (Prakash et al, 2019(Prakash et al, , 2020 were used as the mareials for the study and are detailed in Table 1. Spikes were harvested from vines at maturity and quality dried black pepper was made following hot water treatment (dipping berries for one minute in boiling water before drying).…”

Twenty elite high yielding blackpepper accessons with field tolerance to pollubeetle and phytophthora footrot were evaluated for biochemical principles of quality namely, piperine, essential oil and oleoresin. Two accessions, 7293 and 7252 recorded more than 6.5 per cent piperine which was greater than the maximum recorded value in the black pepper. Accession 7211 had high (5.87%) content of essential oil, while, accessions 7289,7276, 7229,7232 and 7252 211 had high amount of oleoresin . The clustering based on biochemical principles showed that the accessions can be grouped to five major clusters. Majority of the accessions belonged to the cluster V with high piperine, medium oil content and low oleoresin content. Correlation studies indicated that there is no correlation between yield and biochemical principles.
