New snap bean varieties

Abstract

The aim of our selection research was to create new snap bean varieties suitable for all kinds of consumption and processing and also resistant to diseases. We used the following varieties for our crosses: Palanačka Rana, Šumadinka, Zora, Orbane and Hikos. All the varieties possessed yellow pods, but Šumadinka variety had yellow-marbled pods. Zora and Orbane varieties had round pods, Palanačka Rana gave oval-round pods, while Sumadinka and Hikos varieties produced flat pods. Orbane variety showed resistance to Common Bean Mosaic Virus (CBM) (Phaseolus virus 1) and to Colletotrichum lindemuthianum. Applying the Pedigree selection method, we performed individual selections and reciprocal crossing within hybrid population until we achieved the satisfactory level of homozygosity. Two new snap bean varieties, Julija and Darina, were selected as a result of our research. The characteristics of these new varieties are as follows: they were short in length (40 - 45 cm high), early of medium -early maturing-, showing simultaneous and concentrated suitability for all kinds of consumption. The 12 -16 cm long pods were of good quality, yellow or yellow-marbled, with oval or oval-round cut. The yielding ranged from 13-18 t/ha of technologically mature pods with genetic yield potential. The pods possessed both the genetic resistance to Common Bean Mosaic Virus (CBM) and tolerance to Anthracnose of beans.
