Integrated evaluation of pear varieties cultivated in Orenburg Oblast

Abstract

In this article, we carry out an evaluation study of seven pear varieties cultivated in the Orenburg Oblast (Russia), which were planted in 2003. The research covered the period of 2022-2024 and involved the use of standard methods based on a set of economic and biological characteristics. Using oneway analysis of variance at a 5 % significance level, the presence of variability between the varieties was confirmed for all the parameters, except for productivity and yield. In 2024, the plant productivity was affected by frosts during flowering, which led to the death of flowers and ovaries and, as a result, the lack of harvest. The parameters of average productivity, yield, and fruit weight were calculated for the three-year period under study (including 2024 without fruiting). On this basis, the Krasnobokaya (K), Chizhovskaya, Uralochka, and Gvidon varieties were recommended for further selection and cultivation in the conditions of the Orenburg Oblast.
