| Abstract | The heirloom cultivars of pumpkin in Thailand are diverse and valuable for conservation and utilization. Selection of lines for the creation of hybrids is a method of use in the seed industry. The objective of this study was to select the 4th and 5th generations of local pumpkin lines, which were selected by inbred line selection and pedigree methods. Thirty-one lines of the 4th and 5th generations and seventeen lines of 4th and 5th generations of PKT/CMO439 pedigree method lines and 9 standard cultivars were grown to determine for yield, yield components, and quality using RCB design with 3 blocks during October 2022 to April 2023. The results showed the significant differences of all traits except harvesting period. In the evaluation, 13 lines with yields per rai and fruit weight of more than 1.4 tons and 1.7 kg, 21 varieties with a solid content of more than 20.0%, and 5 varieties with a raw pulp total soluble solid content of more than 11.0% were selected. By the independent culling selection was able to select 15 lines from inbred line selection and the pedigree method of 7 and 8 lines, respectively. The selected lines from inbred line selection had higher qualities than the selected lines from the pedigree method. Those qualities included solid content equal to 20.6 and 19.2%. The total soluble solid contents of raw and cooked flesh were 10.1 and 8.0 with 11.1 and 8.7%, respectively. The selected lines can be tested for combining ability in order to select high yield and quality crosses for creating hybrids that are suitable for the seed industry. |
