APETALOID AND PETALOID FEMALE PERFORMANCE ON HORTICULTURAL CHARACTERISTICS OF F1 AMERICAN MARIGOLD (TAGETES ERECTA L.) HYBRIDS
This research’s objectives focused on using two male-sterile systems, apetaloid and petaloid types, as female parents for the F1 marigold cut flower hybrid development. These female lines’ creation came from the same original line, the gynomonoecious line, with five backcrosses to obtain two female lines, FY1502 and FY1502AP. Their crossing with 10 male lines progressed during the summer from April to August 2016. Then, growing the progenies of 20 crosses and four commercial varieties as checks for characterization and evaluation continued in a lattice design with two replications. Planting them in six blocks contained 10 plants per treatment. The data recorded on eight horticultural characteristics include flower diameter, number of petals per flower, calyx length, peduncle length, flower weight, the number of days from sowing to first flowering, plant height, and plant bush diameter, as well as, the morphology of flowers. The results showed that progenies from two female apetaloid and petaloid with the same male line gave similar outcomes; all progenies produced male sterile double-flowers with golden-yellow flowers, except progenies of MY1501 and MY1502, which created yellow flowers. FY1502 gave the same superior F1 progenies as FY1502AP in the diameter of the flower. Based on the results, both females could give good characteristics on flower diameter, calyx length, plant height and bush diameter, and early flowering. However, the heterobeltiosis of the F1 progenies of a few vegetative and reproductive characteristics differed. The FY1502AP gave better progenies in peduncle length heterobeltiosis than those of FY1502 and slightly better for plant bush diameter, whereas FY1502 gave slightly better in flower weight heterobeltiosis than those of FY1502AP. The findings of this study indicate that this apetaloid type could benefit Thailand’s marigold seed production program.
期刊介绍:
The SABRAO Journal of Breeding and Genetics is an international journal of plant breeding and genetics research and was first published in 1969. It is the official publication of the Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO).
Its objectives are to: promote the international exchange of research information on plant breeding and genetics, by describing new research findings, or ideas of a basic or practical nature; and be a medium for the exchange of ideas and news regarding members of the Society.
The Journal gives priority to articles that are of direct relevance to plant breeders and with emphasis on the Asian region. Invited for publication are research articles, short communications, methods, reviews, commentaries, and opinion articles. Scientific contributions are refereed and edited to international standards.
The journal publishes articles for SABRAO members mainly. The Journal preferred strongly that at least one author should be a current member of the Society. Non-members may also publish in the journal.
