Data were recorded on ten characters for each genotype. The phenotypic coefficient of variability was highest for surface area of bush followed by weight of the bud and number of plucking points but lowest for length of the 1st leaf of the shoot. Genotypic coefficient of variability was highest for surface area of bush followed by weight of the bud and number of plucking points and lowest for length of the 1st leaf of the shoot followed by width of 1st leaf of the shoot. 100 seed weight, length of mature leaf, weight of the bud and number of plucking points showed high heritability. The genetic advance was high for 100 seed weight followed by number of plucking points and weight of the shoot. Comparison of mean showed that T-78 Vs Kangrajat, BSS-449 Vs Kangrajat and UPASI-9 Vs Kangrajat, combinations are genetically diverse. Comparison of variance shows that AV-2 and Kangrajat are genetically diverse genotypes. Comparison of both mean and variance shows that AV-2 and kangrajat are genotypically most diverse genotypes. Correlation coefficients at the genotypic level reveal that only three pair of traits, namely, number of plucking points and weight of the shoot, surface area of bush and width of 1st leaf of the shoot, length of mature leaf and width of the mature leaf showed positive and significant phenotypic correlation. Surface area of bush showed negative and significant correlation with weight of the shoot. Path analysis revealed that only four traits, namely, length of the mature leaf, width of the mature leaf, number of plucking points, and width of the 1st leaf of shoot showed high, positive and direct effect on weight of the shoot. Correlation and path analysis revealed that in tea, traits, number of plucking points, length of mature leaf, width of mature leaf and width of 1st leaf of the shoot can be considered important for improving the weight of shoot in tea.ennullCorrelation and path analysis in tea [Camellia sinensis (L).
