The aim of this study was to develop an inbred lines from octoploid strawberry and to determine their breeding value by estimating the effects of general combining ability (GCA) and mid-parent heterosis. All inbred lines were obtained through selfing using five cultivars. The number of inflorescences, number of flowers per inflorescence, fruit yield, fruit number per plant, average fruit weight, number...
Honeyberry’s popularity has been increasing because of its valuable traits: nutritional value of fruits (a high amount of ascorbic acid, potassium and polyphenolic compounds), early ripening (14 days before strawberry), exceptional hardiness and easy cultivation. However, there is still little known about the pollination biology of this species, which is essential for practical breeding purposes....
In the present study genetic diversity between 19 blueberry cultivars was evaluated using Randomly Amplified Polymorphic DNA (RAPD) and Inter Simple Sequence Repeat (ISSR) markers. In total, nine selected RAPD primers produced 89% polymorphic fragments, whereas eleven ISSR primers – 82%. Resolving power value of the RAPD primers ranged from 2.40 to 7.19, whilst ISSR from 1.90 to 5.78. The similarity...
Regarding an increasing interest of consumers towards berry fruit, as they have been proved to have potential health benefits, the nutraceutical fruit value of seven strawberry cultivars: ‘Felina’, ‘Feltar’, ‘Hulta’, ‘Jota’, ‘Pastel’, ‘Plena’ and ‘Teresa’ selected at the University of Life Sciences in Lublin, Plant Genetics and Breeding Department was evaluated in this study. In fruits harvested at...
During the years 2012 to 2014 some research connected with highbush blueberry was taken. It described phenotypic and genotypic variability of 19 cultivars of highbush blueberries grown in the Lublin region. The cultivars included in the study were: ‘Bluecrop’, ‘Bluejay’, ‘Blueray’, ‘Bonifacy’, ‘Bonus’, ‘Brigitta Blue’, ‘Chandler’, ‘Chanticleer’, ‘Croatan’, ‘Darrow’, ‘Duke’, ‘Earliblue’, ‘Herbert’,...
In principle, in vitro propagation results in uniform batches of plants, which grow, flower and fruit normally. However, phenotypic changes often observed in the field performance of tissue culture-produced strawberry plants might affect their agronomic value. So, it is of utmost importance to assess the field performance of in vitro propagated plants to verify their fidelity to conventional propagated...
Blue honeysuckle due to the high health benefits of its fruit, early ripening (before the first strawberries cultivars) and high frost resistance of both plants and flowers has gained the great popularity both in cultivation and breeding. The implementation of the breeding program of new cultivars requires the knowledge of the characteristics that determine its direction in the selected material....
The aim of the research was to assess genetic control, heritability and correlation of some quantitative characters on the basis of hierarchic crossing scheme. In the experiment two systems of classification were applied. In the first one superior classification was made according male forms (5♂ ×4♀) and in the second one female forms were superior (10♀ ×3♂). Genetic control for most analysed traits...
The material for the study consisted of F₁ hybrid populations derived from crosses among strawberry genotypes such as: ‘Calypso’, ‘Evita’, ‘Ostara’, ‘Selva’ and ‘Senga Sengana’. The crosses were conducted in a complete diallel design in accordance with Griffing’s first method. In the analysed model, 8 quantitative characters such as: time of flowering and ripening, number of inflorescences, flowers...
Celem pracy było określenie wartości produkcyjnej wyselekcjonowanych klonów hodowlanych truskawki. Analiza takich cech, jak: termin zakwitania, termin dojrzewania, obfitość kwitnienia, plon owoców, masa pojedynczego owocu wyboru ekstra, procentowy udział owoców ekstra w plonie, kształt owocu, barwa skórki, barwa miąższu, jędrność wykazała znaczne zróżnicowanie pomiędzy badanymi genotypami. Zespołem...
