Abstract
The study on morphological characteristics of sponge gourd (Luffa aegyptiaca Mill.) for germplasm characterization and data utilization support for plant germplasm conservation at Genebank of Department of Agriculture (DOA Genebank) was carried out at Biotechnology Research and Development Office, Pathumthani. Randomized Completely Block Design with 2 replicates was applied to 13 samples of sponge gourd, comprising of L4 (Buab Phuang), L18 (Buab Hawm), L20 (Buab Pom), L22 (Buab Sun), L35 (Buab Hawm Yao), L36 (Buab Hawm), L43 (Buab Hawm Sun), L44 (Buab Hawm Yao), L48 (Buab Hawm), L51 (Buab Hawm Yao), L56 (Buab Hawm Pah), L58 (Buab Yao), and L60 (Buab Hawm). The result showed that all samples were classified as having a Monoecious sex type. Petal colour was listed in Yellow Group consisting of Yellow Group 7A, Yellow Group 7B, Yellow Group 12B, and Yellow Group 13B. Fruit ribs showed superficial appearances. Average fruit weight was 269.662 grams. The average number of fruit per plant was 23. The young fruits had sweet taste and high nutritional value. The fibers from the mature fruits can be used for body cleaning and household items, etc. It was also found that L4 had obviously shortest fruit size at 7 cm. The matured seed color of total samples can be grouped in Black Group 202A, Black Group 203A and Black Group 203B. The average weight of 100 seeds across all samples was 9.771 grams. The data obtained from this research will be used as a database for the conservation of Luffa spp. of DOA Genebank.
