| dc.description.abstract | Investigations on “Evaluation of ecotypes of long pepper (Piper longum L.) was undertaken at the Department of Plantation Crops and Spices at College of Horticulture, Vellanikkara during the period 2005-2007.The major objective of the study was to evaluate various ecotypes of Piper longum available at the Department of Plantation Crops and Spices for their variability in yield, morphological and biochemical characters so as to identify the superior types. Twenty accessions genetically catalogued and studied for their variability in vegetative, reproductive and biochemical characters and found that all the accessions varied with respect to these characters. The vegetative, reproductive and biochemical characters were compared with the characters of the released variety; Viswam and the accessions, which performed on par with Viswam, were identified. Correlations of the various vegetative and reproductive characters were worked out with the dry spike yield and significant positive correlations were observed for nine characters like number of vegetative branches per stem, number of spike bearing branches per stem, total number of leaves per hill, number of spikes per spike bearing branch, length of spike, girth of spike, fresh weight of spike, dry weight of spike and fresh yield per plant Based on the above studies a few accessions which were statistically on par with the check variety Viswam could be identified. This preliminary evaluation gives only an indication and evaluation of the accessions has to be 3-4 years for obtaining confirmatory result. | en_US |
