Perspektivni hibridi višnje (Prunus cerasus L.) stvoreni u Institutu za voćarstvo u Čačku
Promising sour cherry hybrids (Prunus cerasus L.) developed at Fruit Research Institute Čačak
Abstract
Oplemenjivački rad na stvaranju sorti višnje (Prunus cerasus L.) u Institutu za voćarstvo u Čačku kao osnovne ciljeve postavlja rodnost, krupnoću i kvalitet ploda, kao i otpornost prema prouzrokovačima bolesti i štetočinama. Kao rezultat planske hibridizacije oko 40 sorti u više od 110 roditeljskih kombinacija, stvoreno je preko 10 000 hibridnih sejanaca. Među njima, dva su do sada priznata za sorte - 'Čačanski rubin' ('Shasse Morello' x 'Köröser Weichsel') i 'Šumadinka' ('Köröser Weichsel' x 'Heimanns Konserven Weichsel'). Na bazi desetogodišnjih ispitivanja 11 hibrida, odabranih iz populacije od oko 3000 hibridnih sejanaca, četiri su izdvojena kao elitni (III/23, III/31, II/40 i XII/57), i u postupku su priznavanja za nove sorte. U radu su prikazani dvogodišnji rezultati ispitivanja vremena zrenja, pomoloških osobina, biohemijskog sastava ploda i poljske otpornosti prema prouzrokovačima bolesti i štetočinama ovih genotipova, poređenih sa osobinama standardne sorte 'Heimanns Konserven... Weichsel'. Masa ploda, sadržaj rastvorljivih suvih materija i šećera kod ispitivanih hibrida su bili viši u odnosu na standardnu sortu. Oni takođe pokazuju značajan stepen poljske otpornosti prema prouzrokovačima monilioze koštičavih vrsta voćaka (Monilinia laxa /Ader et Ruhl./ Honey ex Whetz.), ljubičaste pegavosti lišća trešnje i višnje (Blumeriella jaapii (Rehm.) v. Arx.), šupljikavosti lišća trešnje i višnje (Clasterosporium carpophilum (Lév.) Aderh.), kao i napadu trešnjine muve (Rhagoletis cerasi L.).
At Fruit Research Institute in Čačak, major objectives of the work on breeding new sour cherry (Prunus cerasus L.) cultivars are high cropping, large, high-quality fruits and resistance to causal agents of diseases and pests. As a result of the planned hybridization, more than 10,000 hybrid seedlings have been developed from about 40 cultivars within more than 110 parental combinations, among which are 'Čačanski rubin' ('Shasse Morello' x 'Köröser Weichsel') and 'Šumadinka' ('Köröser Weichsel' x 'Heimanns Konserven Weichsel') which have been named and released. Ten-year study of 11 hybrids, selected from the population of about 3,000 hybrid seedlings, gave four hybrids which have been singled out as elite (III/23, III/31, II/40 i XII/57). These hybrids are currently under procedure of being released as new cultivars. The paper presents two-year results of the study of ripening time, pomological properties, biochemical composition of fruits, and field resistance to causal agents of dise...ases and pests attacking the above named genotypes which were compared to standard cultivar 'Heimanns Konserven Weichsel'. In the studied hybrids, fruit weight, soluble solids content and sugars content were higher than in standard cultivar. In addition, they exhibit substantial field resistance to causal agents of brown rot (Monilinia laxa /Ader et Ruhl./ Honey ex Whetz.), cherry leaf spot (Blumeriella jaapii (Rehm.) v. Arx.), shot-hole (Clasterosporium carpophilum (Lév.) Aderh.) and cherry fruit fly (Rhagoletis cerasi L.) attack.
