ABSTRACT
Twenty two black pepper genotypes were evaluated for growth and morphological characters based on shoot tip colour, leaf and spike nature under arecanut based mixed cropping system during 2015-16 in Uttara Kannada (Dist.), Karnataka. Among the genotypes maximum vine height was recorded in the genotype SV-8 (9.40m). The mean number of branches per sq.m area at 10 ft height were recorded highest in the genotype SV-12 (93.33Nos.) and spike length (20.60cm) was recorded in var. Panniyur-1 followed by SV-12 and SV-20 (17.30cm each). The leaf length was observed highest in genotype SV-19 (20.62cm) while broader leaves in SV-7 (13.73cm) and maximum petiole length (2.97cm) in genotype SV-21. The genotype SV-21 showed highest chlorophyll content of (2.49mg/g). The higher number of stomata per unit area of leaf was seen in genotype SV-2 (12.87) and minimum in SV-8 (9.50). The var. Panniyur-1, SV-18 and SV-21 showed light green shoot tip colour, whereas, SV-6, 16, 17 had dark purple while, others were having light purple. The var. Panniyur-1, genotype SV-3, 17, 19 and SV-20 had hanging type of lateral branching pattern while, semi erect types were observed in SV-4, 8, 10, 13, 15, 16 and SV-21 whereas, the remaining genotypes had horizontal type of branches. The morphological characters of leaf were observed viz., leaf venation, leaf shape, lamina shape, leaf margin, leaf texture were varied among the genotypes similar kind of variation were recorded in spike characters like, spike twisting, spike shape and spike setting.
