Abstract/ Executive Summary:

Genetic diversity in 31 potato genotypes (parents and their hybrid progenies) was determined using multivariate analysis. Cluster analysis revealed that the parents and their hybrid progenies could be grouped into five different clusters. The maximum number of genotypes were included in clusters II and V. Cluster V had maximum and cluster I had minimum intra-cluster distance. Cluster mean showed wide range of variation for several characters among single as well as multi-genotypic clusters. Considering diversity pattern, parents should be selected from clusters I, III and V for the improvement of potato.

Keywords: Genetic diversity, Cluster analysis, Potato

Location: Research field of Institute of Biological Sciences, Rajshahi University, Rajshahi

Start Date: 15-11-2001

End Date: 15-01-2002

Program Area: Variety and Species

Commodity: Potato

Objectives:

The present study was undertaken to analyze the genetic divergence in 31 potato genotypes.

Methodology:

Thirty one genotypes of potato were grown in the research field of Institute of Biological Sciences, Rajshahi University, Rajshahi. The experimental design was RCBD with four replications. Each replication consists of 31 plots. Each plot having two rows of 40 plants. Row to row and tuber to tuber distance was 60 and 20 cm, respectively. Recommended dose and application methods of fertilizers were used. To get good crop conditions irrigation, intercultural operations, spraying of insecticide and fungicides were performed. The planting was done on 15 November 2001 and the harvesting was made after 90 days of planting. Observations were recorded and calculated on ten randomly selected plants from each plot on days to emergence (DE), plant height (PH), number of stems/plant (NS), number of tubers/plant (NT), tuber weight/ plant (TW), individual tuber weight per plant (ITW), tuber dry-matter content (DM%) and tuber weight loss due to respiration 150 days after harvest (TWL%). Data were subjected to principal component and Mahalanobis (1936) D² analysis extended by Rao (1952) using GENSTAT 513 Computer programme.

Achievement/Findings:

The crosses involving parents belonging to the maximum divergent clusters were expected to manifest maximum heterosis and also wide variability in genetic architecture. Thus crosses among the genotypes of clusters I, III and V would exhibit high heterosis and is also likely to produce new recombinants with desired characters in potato.
