Productivity and fruit quality of Jonagold clones of home selection Texto completo
2014
New results of the clonal selection of apple tree (Malus domestica Borkh) conducted at Podillya Research Station of Horticultural Institute NAAS by method of state variety testing have been presented. By the results of the 6-year studying (2007 - 2012) of 20 new Jonagold clones of domestic selection their estimation was carried out according to the complex of such qualities as productivity, early ripening, marketability, taste qualities and durability of fruits. The following clones are defined to be the best: DP-16, DP-17, DP-18, DP-20. They start fruiting in the age of 2 or 3 years, productivity of the 5- or 6-year-old trees reaches 8,3–25,5 tons per hectare, quantity of the fruits of the highest and first grade is about 57–76% (in 2010–2012). Fruits of the mentioned clones are bigger than medium size (DP-16), big (DP-17, DP-18) and very big (DP-20); they have average similarity, excellent and very harmonious sour-sweet taste (8,3–8,7 points). Fruits of the best clones kept their quality for 202 – 220 days.

The article presents results of characteristics studying for generative and vegetative parts of soft winter wheat in the conditions of autumn moisture shortage and in the conditions of optimal moisture supply. During the period of studies a dramatic difference of the levels of generative and vegetative parts of plants has been observed. As a decreased level of characteristics development has been noted, so its increasing, in particular, among the varieties of generative part. within 7.2% (thousand seed weight) to 42.6% (seed weight per ear). It is found that efficient development of generative organs is subject to variety bushing capacity, in particular at spring. The article also shows that stress conditions of autumn period influence late emergence of seedlings; however, that goes along increased level of some characteristics development at generative part. Obviously, during such years the selection of breeding material as per ear yield would not be efficient. The article, for the purpose of excluding negative consequences of selection, pays special attention to such characteristics as that not affected by stress environmental conditions. This indicates genetic stability of those characteristics, so their use as marker characteristics in yield specific breeding is advised.

Race-specific resistance of 19 common millet varieties that are firstly listed on the State Register of Plant Varieties Suitable for Dissemination in Ukraine in 2013 is assessed. It is found that almost half of the varieties are infected with all smut races, part of them is resistant only to the first group of smut races, and there is no variety to be resistant to all races of this disease. It is concluded that common millet varieties are needed to be examined for resistance to smut races
