Journal Title: Plant varieties studying and protection - Year 2017, Vol 13, Issue 1
Abstract
Purpose. To establish the reasons of submitting not highly decorative lilac hybrids to state variety testing so that unpromising varieties and look-alikes can be sometimes included in the world collection, and focus on solving this situation. Methods. Analytical approach. Results. It was established why and how unoriginal hybrids were submitted to state variety testing that for several reasons can allow them to obtain the status of variety. Conclusions. In order to prevent obtaining the status of variety by some low decorative lilac hybrids, it is necessary that both a breeder and testing stations employer should use known presentable collections of identified varieties for evaluation of real value of a new hybrid. In Ukraine, there is such a collection at N. N. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine where more than 130 varieties and 21 species of the genus Syringa occupies the area of 2.35 ha. It is desirable to compare not only with the check variety that the breeder selected for his hybrid among such, but, if it is possible, with all varieties in the collection close to it by decorative effect. The problem is that the author of a hybrid, sometimes ignorantly or for some other reason, selects a check variety for his hybrid that is not the most decorative one among such, against which a candidate for variety status will be more attractive during its evaluation. In such a case, the breeder should change a check variety that permits to estimate really the decorative effect of a submitted hybrid.
