Abstract

This research was conducted to examine the fruit characteristics of selected walnut genotypes from the native population of Eastern Serbia. Over 28 trees that deserve attention were recorded through the selection procedure. By grafting, grouping and cultivation under the same conditions at the Fruit Research Institute in Cacak, seven promising genotypes with the most favourable fruit characteristics were identified. Important physical properties of the fruit, such as fruit weight, kernel weight, fruit dimensions and some kernel and shell properties were investigated. The fruits of the selected genotypes were large or very large. The fruit weight ranged from 13.4 to 17.9 g, whereas the kernel weight varied from 6.22 to 8.92 g. The kernel was light-coloured or yellow, of very good taste. The kernel percentage in the tested genotypes was high, over 50.0% (50.7-55.3%). Pearson's correlation coefficient revealed a significant correlation between fruit and kernel characteristics. PCA analysis showed an adequate grouping of genotypes based on fruit quality. The obtained results suggest that selected promising walnut genotypes showed very good fruit properties, and may contribute to the increase of walnut production in the future.
东塞尔维亚地区有发展前景的核桃基因型的果实特性
本研究旨在研究来自东塞尔维亚本地种群的选定核桃基因型的果实特性。通过筛选程序,记录了28棵以上值得关注的树木。在Cacak果树研究所,通过嫁接、分组和相同条件下的栽培,鉴定出7个具有最有利果实性状的有前途的基因型。研究了果实的重要物理特性,如果实质量、果仁质量、果实尺寸以及一些果仁和壳的特性。所选基因型果实大或非常大。果实重13.4 ~ 17.9 g,籽粒重6.22 ~ 8.92 g。果仁呈浅色或黄色,味道很好。籽粒率在各基因型中较高,均在50.0%以上(50.7 ~ 55.3%)。Pearson相关系数显示,果实与果仁性状之间存在显著的相关性。主成分分析表明,根据果实品质对基因型进行了适当的分组。结果表明,所选的核桃基因型具有良好的果实性状,对今后核桃产量的提高有一定的促进作用。
