Abstract

ABSTRACT This article reflects on the conventional open pollination breeding method of the genus Hylotelephium. Six-year-old seedlings were evaluated and compared with the mother plants for 3 years. A total of 1 063 seedlings were evaluated (54 in the H. ‘Red Cauli’, 90 descendants in the H. ‘Xenox’, 919 descendants in the H. ‘Purple Emperor’). This study deals with six evaluated characters of vegetative parts of plants (habit, height and width of plants, length and width of leaves and the colour of the upper side of the leaves). The most significant phenotypic variability was confirmed for habit, plant height, leaf colour in summer and leaf length in population H. ‘Xenox’ and for spring colouration of lower leaves in population H. ‘Red Cauli’. The highest degree of variability was found for plant height, where the monitored populations split into a total of seven different sizes. On the contrary, the lowest degree of variability was demonstrated for the length and width of leaves, where all populations showed shorter and narrower leaves compared to the mother plants, with minimal differences.

三个水仙属品种开放传粉幼苗表型变异的评价

摘要本文对传统的水蛭属开放传粉育种方法进行了反思。对6年幼苗进行评价，并与母株进行3年比较。共对1 063株幼苗进行了评价，其中“红茎”54株，“Xenox”90株，“紫帝”919株。本文研究了植物营养部分的6个评价性状(习性、植物的高度和宽度、叶片的长度和宽度以及叶片上部的颜色)。表型变异最显著的是习性、株高、夏季叶色和叶长，以及春季红茎叶的下部叶色。植物高度的变异程度最高，被监测的种群分为七种不同的大小。相反，叶片长度和宽度的变异程度最低，所有种群的叶片都比母株短、窄，差异极小。

期刊介绍： Folia Horticulturae is an international, scientific journal published in English. It covers a broad research spectrum of aspects related to horticultural science that are of interest to a wide scientific community and have an impact on progress in both basic and applied research carried out with the use of horticultural crops and their products. The journal’s aim is to disseminate recent findings and serve as a forum for presenting views as well as for discussing important problems and prospects of modern horticulture, particularly in relation to sustainable production of high yield and quality of horticultural products, including their impact on human health.
