Abstract/ Executive Summary:

A field experiment was performed to the study morphological analysis, growth, and yield of fifteen sweet potato germplasm at the Horticulture Farm, Sher-e-Bangla Agricultural University, Bangladesh, from September 2018 to March 2019 following Randomized Complete Block Design (RCBD) with three replications. Fifteen sweet potato germplasm were collected from different countries based on skin and flesh colors of root tuber were used in this experiment. Based on the directions of the Union for the Protection of Plant Varieties (UPOV), they were classified according to their morphological differences. Different vegetative growth, reproductive growth, and yield contributing parameters were studied and different germplasm showed different results from each other. Among them, a maximum number of tuberous roots/plants (7.3) was observed from G4. On the other, the utmost weight of a single root tuber (157.4 g), tuberous root yield/plant (1091.0 g), and tuberous root yield/ha (60.6 t/ha) were observed in G7. In addition, statistically identical results were found in tuberous root yield/ha in G3 (59.1 t/ha). The germplasm G1, G2, G3, G4, G5, G6, G7, G9, G12, and G14 can be utilized to have potential due to higher yield compared to our local variety. Furthermore, yield with color observation G11 may also have the prospects. This study would be effective for further research for researchers and breeders to adapt and recommend them in our country to pomp the agriculture sector.

Start Date: 00-09-2018

End Date: 00-03-2019

Program Area: Variety and Species

Commodity: Sweet potato

Objectives:

To evaluate the potential sweet potato germplasm through studying morphological, vegetative growth, and yield contributing characteristics.

Methodology:

This research work was carried out at Horticulture Farm, Sher-e-Bangla Agricultural University, Sher- e-Bangla Nagar, Dhaka-1207. The duration of the experiment was from September 2018 to March 2019. The research was implemented to evaluate the morphological characteristics, vegetative growth, and yield performance of 15 selected sweet potato germplasm. They were collected from different countries according to different skin and flesh colors of root tuber and were denoted for this study as G₁, G₂, G₃, G₄, G₅, G₆, G₇, G₈, G₉, G₁₀, G₁₁, G₁₂, G₁₃, G₁₄, and G₁₅. Among them, G8 collected from Bangladesh was used as a check-in in this study. The study was laid out in the Randomized Complete Block Design (RCBD) with three replications. In the experimental area, a total of 45 plots was created. Vines of sweet potato with 4-5 nodes were planted on the plots. Plant to plant distance 30 cm and row to row distance 60 cm were maintained in planting vines. In each plot, there were ten plants and each block contained a total of 150 plants. Fertilizers and manures were applied following BARI recommended doses. Irrigation was applied twice at the vegetative stages and earthing up, weeding operation was also done manually. When the crops became fully matured, harvesting all the germplasm was done on the 2nd week of March 2019 and the entire field was harvested. Data on different morphological characteristics were recorded following Union of Protection of Plant Varieties (UPOV) guidelines based on visual observation and represented into appropriate categories. Data have also been collected based on vegetative growth and yield attributing parameters. Three plants were randomly selected from each unit of the plot for the collection of data. The plants in the outer rows and the extreme end of the middle rows were excluded from the random selection to avoid the border effect. Data on leaf length (cm), leaf width (cm), length of internode (cm), petiole length (cm), flower stalk/peduncle length (cm), tuberous root length (cm), tuberous root diameter (cm), number of tuberous roots/plants, the weight of a single tuberous root (g), tuberous root yield/plant (g), tuberous root yield/ha (t) were measured. The data recorded for different vegetative and yield contributing parameters were statistically analyzed using the MSTAT-C computer package program to determine the significance of variation among the treatments. Differences between germplasm were evaluated by the Least Significance Difference test (LSD) at a 5% level of significance.

Achievement/Findings:

After observing and analyzing all the data, it can be concluded that there were significant differences among fifteen sweet potato germplasm studied in terms of different growth and yield-related parameters. Though the present study categorized the sweet potato germplasm based on the different morphological parameters and evaluated their growth and yield performances, this information is surely an informative source for the researchers and breeders to recommend better cultivars and improve production technology.
