Chrysanthemum indicum L. – commonly called Indian chrysanthemum, is a small-flowered chrysanthemum of the Asteraceae family, one of the oldest cultivated flowering plants. The creation of the chrysanthemum collection of “Alexandru Ciubotaru” NBGI started in 1954, with the beginning of the introduction of new cultivars from other countries. The work on breeding of chrysanthemums started in 1959, in the Floriculture Laboratory, under the leadership of N. L. Sharovaya. Since then, the ecological situation has changed significantly and it has become necessary to update and enrich the collection with new local cultivars that are resistant to the conditions of urbanization. Therefore, the goal of our research was to obtain our own cultivars of chrysanthemums of high ornamental value that would thrive under the conditions of Moldova. Our breeding work has been focused on obtaining early-flowering cultivars with low, compact, abundantly flowering bushes and with tall and vigorous shoots, on which numerous highly decorative inflorescences are formed. In our research, we used free cross-pollination of various groups of parent cultivars. As a result, mature seeds were obtained, from which 2000 seedlings with various characteristics and properties were subsequently grown, which made it possible to carry out interesting selections. Based on the results of studies that were carried out on the site for the State Variety Testing, during several years, the most promising breeding forms for obtaining cultivars were selected. The cultivars were tested according to the methods indicated by The International Union for the Protection of New Varieties of Plants, updated and adapted for use under our conditions. Thus, in 2016, certificates were obtained for the cultivar 'ZEFIR', and in 2017, the cultivar 'FĂCLIA', in 2019, the cultivar 'CAPITOLINA', in 2021, testing of the cultivar 'GINGĂȘIE', which were obtained on the basis of our collection. Our studies have shown that the most diverse and viable offspring of chrysanthemums is obtained by involving free cross-pollination of parental varieties. If their combination is successful, the offspring is obtained, being characterized by great diversity of shape and colour of inflorescences, height and habit of the bush, foliage and even flowering periods. The new local cultivars are highly decorative, resistant to diseases and pests, as well as adverse conditions, can be recommended for wide use in landscaping, container culture, as cut flowers. |
