Multivariate Analysis on the Quantitative Characters of Bottle Gourd [lagenaria Siceraria (mol.) Standl.]

Abstract/ Executive Summary:

Seventeen bottle gourd genotypes originating from different regions of Bangladesh were subjected to cluster analysis. The genotypes were constellated into four distinct groups with the range of 3 genotypes in cluster II and III to 7 in cluster I. The inter-cluster distance in all cases was larger than the intra-cluster distance suggesting wider genetic diversity among the genotypes of cluster II and III followed by cluster I and III and the minimum was found between genotypes of cluster II and IV. The highest intra cluster value (1.0) was observed in cluster II due to the presence of variations among the genotypes. Mean performance of different clusters revealed that cluster III recorded the highest mean for number of fruits per plant, individual fruit wt. (g) and fruit yield (t/ha) with second highest mean for fruit length (cm), whereas fruit length (cm) was n cluster I with the highest means. Therefore, more emphasis should be given on cluster III for selecting genotypes as parents for crossing with the genotypes of cluster I which may produce new recombinants with desired traits.

Keywords: Multiariate Analysis, Quantitative characters, Bottle gourd .

Location: Horticultural Research Centre, Bangladesh Agricultural Research Institute, Gazipur

Start Date: 00-09-2005

End Date: 00-00-2006

Program Area: Variety and Species

Commodity: Bottle gourd

Objectives:

To assess the extent of genetic diversity in 17 bottle gourd genotypes which will help to select prospective parents to develop transgressive segregates.

Methodology:

The experiment was conducted at the Olericulture Division of Horticulture Research Centre, Bangladesh Agricultural Research Institute (BARI) during the winter season 2005-06 with seventeen genotypes of bottle gourd. The seeds of these genotypes were sown on the seed bed on 15^th September 2005. Twenty days old seedlings were transplanted in the main field on 5^th October 2005. The experiment was laid out in a Randomized complete Block design with three replications. The rest of urea and MP were applied in four equal installments at 21, 35, 55 and 75 days after transplanting. Data on days to 1^St harvest, fruit length (cm), fruit diameter (cm), number of fruits/ plant, individual fruit weight (kg), fruit yield (t/ha), fruit shape and fruit colour were recorded from three randomly selected plants per replication. Statistical analyses were carried out using Genstat 5 software.

Achievement/Findings:

The highest intra cluster value (1.0) was observed in cluster II due to the presence of variations among the genotypes. Mean performance of different clusters revealed that cluster III recorded the highest mean for number of fruits per plant, individual fruit wt. (g) and fruit yield (t/ha) with second highest mean for fruit length (cm), whereas fruit length (cm) was in cluster I with the highest means. Therefore, more emphasis should be given on cluster III for selecting genotypes as parents for crossing with the genotypes of cluster I which may produce new recombinants with desired traits.
