Abstract
"Sixteen genotypes of long pepper were assessed for variability, correlation and path analysis for yield and its attributes. The differences among genotypes were statistically significant for all the fifteen quantitative characters . High estimates of genotypic coefficient of variation, heritability and genetic advance were shown by number of spikes/plant, number of spike bearing branches and internodal length of spike bearing branch, respectively. This is an indication that selection based on the above spikes will be more effective for crop improvement programme. Correlation studies among the fruits indicated that number of spike bearing branch/plant had high significant positive association with fruit yield at both phenotypic and genotypic levels followed by spike length. Path analYSis of fruit yield revealed that number of spikes/plant, number of primary branches, leaf area, vine length, days of first emergence of spike, spike girth and fruit weight had high to moderate direct effect on yield which indicated their better prospects for further crop improvement."
