Abstract
Aim. The main purpose of studying hybrid forms of peach is to single out the most valuable ones for further breeding practice, improve the existing assortment of peach and transfer new cultivars to the State Commission for Variety Testing of the Russian Federation. Methods. To distinguish forms characterized by a set of indicators of economically valuable traits, a cluster method of comparative evaluation of hybrids with control cultivars of the corresponding fruit ripening period was carried out and pair correlation coefficients of these traits were determined. Results. As a result of the study, the greatest correlation was found between productivity and laying of generative buds, fruit mass and frost damage to the buds in winter; laying buds and frost damage to the buds in winter; fruit taste and dry matter content and their ripening period; solids content and total sugar; damage to generative buds by return frosts in spring with frost damage in winter. Main conclusions. 7 hybrid forms distinguished by a set of traits: Veteran x Favorita Morettini 80-686, Zlatogor x Uspar-I 80-367, Golden Jubilee self-poll. 65-105, Tszy-yan-shuj-mi-tao x Collins III 1/3, Veteran free poll., Laureat x Zlatogor 73-6, (Podarok Kryma free poll, x Tovarishch) 85-104, we recommend using it in the breeding process to improve the existing assortment of peach.
