Selection of vineyard peach types with the aim of a generative rootstocks production

Abstract

In 14 vineyard peach types, selected form collection orchard of the School Agricultural Holding "Radmilovac", of the Faculty of Agriculture in Belgrade, some properties of parent trees and its seedlings were observed with the aim of their recommendation for the generative rootstock production. Fruits of investigated types ripened from August 25 till September 10. The lowest, i.e. highest stone weight was recorded in the type n/1 (4.47 g), i.e. the type XDC/21 (7.74 g), respectively. Vineyard peach types also differed in their vigor. High germination (over 75%) was detected in seeds of 10 types, while good vitality (over 50%) was recorded in seedlings of eight vineyard peach types. Differences between vigor and the level of property uniformity were established in seedlings populations. Based on seed germination and seedlings vitality, considering vigor and uniformity of seedlings, types 1/6, n/1, XLX/23, XIX/28 and XIX/30 can be recommended for the generative rootstock production.

Kod 14 tipova vinogradske breskve selekcionisanih iz kolekcionog zasada na oglednom školskom dobru Poljoprivrednog fakulteta "Radmilovac" u Beogradu proučavane su važnije osobine matičnih stabala i njihovih sejanaca, kako bi neki od njih mogli da se preporuče za proizvodnju generativnih podloga. Plodovi proučavanih tipova sazrevali su u periodu od 25. avgusta do 10. septembra. Najmanju masu koštice imao je tip W\ (4,47 g), a najveću tip XIX/21 (7,74 g). Tipovi vinogradske breskve su se razlikovali i po bujnosti. Dobru klijavost (preko 75%) imalo je seme 10 tipova, a dobru vitalnost (preko 50%) sejanci 8 tipova vinogradske breskve. Ustanovljene su i razlike u bujnosti kao i u stepenu ujednačenosti osobina u populacijama sejanaca. Na osnovu klijavosti semena i vitalnosti sejanaca, ali uzimajući u obzir i bujnost i ujednačenost sejanaca za dobijanje generativnih podloga mogu se preporučiti tipovi sa oznakama 1/6, II/l, XDC/23, XIX/28 i XIX/30.
