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."
