THE ASSESSMENT OF QUALITY INDEXES OF HYBRID SIBLINGS OF THE HAZEL NUTS (CORYLUS AVELLANA L.)

Abstract

The assessment of 59 hybrid siblings of the common hazel is presented in this article: according to an average mass of a nut, output of the walnut kernels, shell thickness and palatability. The research was being held in conditions of Kirov region in 2012-2014. The aim of research was to distinguish large-fruited forms, with a good output of the walnut kernels, thin shell and high palatability. According to an average mass of a nut, the hybrid siblings 1-5-34, 1-1-3, 3-12-27, which authentically had outreached the index of the characteristic in a sample, were selected. During the period of the research, according to the output of the walnut kernels, the sibling 2-9-40 was distinguished, it is prominent by stability and increasing of the average index. The siblings with a thin shell are absent in studied hybrid material of common hazel. The form 2-7-30 with average shell thickness was sorted out for the further research. The all studied hybrid material is differed by perfect palatability of the nuts which characterizes their consumer properties in a profitable way. The forms 2-7-31 and 3-12-28 with perfect nut palatability were distinguished (4,5 – 5,0 points).
