Abstract/ Executive Summary:

Twenty-nine varieties released from Tuber Crops Research Center, Bangladesh Agricultural Research Institute, Gazipur-1701, Bangladesh were characterized at BSPC Debigonj in 2012-13. Among the twenty-nine varieties, data were collected on large number of parameters instructed in Descriptor for the Cultivated Potato by IBPGR, Rome, Italy.

Keywords: Potato , Variety, Mophological characterization, Photographic documentation

Location: Debigonj, Panchagarh

Start Date: 10-10-2012

End Date: 04-04-2013

Program Area: Variety and Species

Commodity: Potato

Objectives:

1. To characterize the released potato varieties 2. To develop photographic monograph with descriptors

Methodology:

Twenty-nine high yielding potato varieties as promising cultivars released from Tuber Crops Research Center (TCRC) of Bangladesh Agricultural Research Institute (BARI) were evaluated during 2012-13 at Debigonj, Panchagor, Bangladesh.The unit plot size was 3m x 3m without replications. Whole tubers (BSPC, Debigonj source) was planted with a spacing of 60 cm × 25 cm. Planting was done during the second week of November, 2012. Fertilizers were applied @ 325-220-250-120 kg/ha of urea, TSP, MOP and gypsum, respectively. Necessary intercultural operations were done as per TCRC recommendation. Data were collected at particular stages of growth, accessions were characterized and evaluated for 21 qualitative and 16 quantitative morpho-agronomic characters using the Descriptor for the Cultivated Potato by IBPGR, Rome, Italy (Huaman et al., 1977). For each accession, ten randomly chosen plants were used for scoring of the characters. Data weere analyzed Shannon-Weaver Diversity Index (SWDI): Quantification of variability for each character was done using the Shannon-Weaver Diversity Index. Estimate of variability for each qualitative character was computed using the standardized Shannon-Weaver Diversity Index, designated as H’ and has the formula: H’= -∑Pi(log2Pi)/log2 n. Where, Pi is the proportion of the total number genotypes belonging to the ith class.Following the work of Siopongco et al. (1999).Mean data for each characters was subjected to multivariate statistical analyses using Principal Component Analysis (PCA), Principal Coordinate analysis (PCO), Canonical Vector Analysis (CVA) and Cluster Analysis using GENSTAT 5 (Released 4.1) software (Copyright, 1997).
