A monograph “Vegetation and biotopes of the “Narochansky” National Park was published in Minsk, Belarus in 2017, edited by A. V. Pugachevsky (Grummo et al., 2017). It includes the Map of terrestrial vegetation (S. 1 : 60 000) and the Map of biotopes (S. 1 : 60 000). Some small-scale maps such as the Map of changes in forest cover of the “Narochansky” National Park for the period 1985–2016, the Map of forest loss in the “Narochansky” National Park for the period 1985–2016 and a series of inventory and analytical maps on the basin of the Naroch Lake are given. This monograph can be considered as a small regional Atlas with detailed explanatory texts to the maps. It presents the experience on vegetation mapping accumulated in the Laboratory of Geobotany and Vegetation mapping of the Institute of Experimental Botany of the National Academy of Sciences of Belarus. Despite some critical comments, mainly concerning the biotope map, this publication of Belarusian geobotanists deserves an approval. They received the full answers to the questions posed: “What do we protect?” and “What is a current state of the vegetation of the National Park and the main trends of its dynamics? Cartographic design is made at a high level; the maps have both scientific and practical importance in the planning of environmental and economic activities.

Abstract The double-flower phenotype has been selected by humans for its attractiveness in various plant species and it is of great commercial value for the ornamental market. In this study we investigated the genetic determinant of the dominant double-flower trait in carnation, petunia, and Rosa rugosa, and identified mutant alleles of TARGET OF EAT (TOE)-type genes characterized by a disruption of the miR172 target sequence and of the C-terminal portion of the encoded protein. Despite the phylogenetic distance between these eudicots, which diverged in the early Cretaceous, the orthologous genes carrying these mutations all belong to a single TOE-type subgroup, which we name as PETALOSA (PET). Homology searches allowed us to identify PET sequences in various other species. To confirm the results from naturally occurring mutations, we used CrispR-Cas9 to induce lesions within the miR172 target site of Nicotiana tabacum PET genes, and this resulted in the development of supernumerary petaloid structures. This study describes pet alleles in economically important ornamental species and provides evidence about the possibility of identifying and engineering PET genes to obtain the desirable double-flower trait in different plants.

Tuberose (Polianthus tuberosa) is an important ornamental plant in Indonesia that has been cultivated by farmers for a long time mainly in Java and North Sumatra provinces. However, the availability of new superior varieties is only a few so that the consumers only have a limited choice. Until now, there are three types of tuberose in Indonesia, which is distinguished by the type of flower namely single, semi-double and double flower. Some breeding efforts to obtain new varieties have been done through crossbreeding, mutation induction and selection to local cultivars. But the success on the crossbreeding of tuberose was only about 0.05%, as it can only be done in the direction of the single flower with double flowers. Because in the double flowers pistils are not found, the variability is very low. Nevertheless from these crossbreeding obtained 29 genotypes that showed differences in several characters, especially in the arrangements of flowers; and flower stalks straightness and rigidness. The other study indicates that each genotype has a different resistance levels against leaf spot disease (Xanthomonas sP.). Meanwhile, breeding of tuberose through mutation induction technique has not been widely studied. Application of gamma ray irradiation on tubers caused morphological damaged on Polyanthes, reduced bulb growth less than 30% and reduced the plant height more 400% than no treated plants (control). Polyploidy induced mutations by using colchicine led to changes in the length and diameter of the flowers and harvesting time. Until now, there is no result of the crossbreeding and mutation techniques that released as a new variety. Despite this, based on the positive selection breeding on local cultivars, there have been two superior genotypes released as new varieties namely Dian Arum (double flower type; origin of Cianjur, West Java) and Roro (semi double flower type; origin of Pasuruan, East Java).  Keywords: Polianthes tuberosa ; breeding; local cultivars, new varieties,Dian Arum, Roro Anteng
