Abstract
The floriculture industry has rapidly developed in Indonesia. One of the potential genera of orchids is Phalaenopsis. New varieties must be developed to compete with imported ones. Genetic improvement of Phalaenopsis has been carried out through interspecific and intergeneric crossing - the crossing between P. I Hsin Bee x P. pulcherrima var. champorensis is dedicated to introduce harlequin type to P. pulcherrima. Forty progenies of the first generation (F1) and their parents are used for the characterization and evaluation. The results show that P. pulcherrima is more dominant (50%) in flower shape and color based on the progeny composition. The introduction of the harlequin type into P. pulcherrima is indicated by 35% of progenies have dark colour at the flower and matched with the spotted pattern of the female parent, indicating that the female contributed partially to the respected traits. The progenies are divided into five distinct groups based on nine qualitative characteristics. Three progenies, namely D829-4, D829-6, and D829-8, are considered to have prominent features, such as more stable and symmetric coalescence of red-brownish blotches on the flowers, representing harlequin type than other progenies. These progenies will potentially be developed to be commercial varieties.
新品种蝴蝶兰 I 新蜂 X 蝴蝶兰 pulcherrima 变种 champorensis 杂交后代评价
印度尼西亚的花卉栽培业发展迅速。蝴蝶兰是具有潜力的兰花品种之一。必须培育新品种才能与进口品种竞争。蝴蝶兰的遗传改良是通过种间杂交和属间杂交进行的--P. I Hsin Bee x P. pulcherrima var.第一代(F1)的 40 个后代及其亲本被用于特征描述和评估。结果表明,根据亲本的组成,P. pulcherrima 在花形和花色方面更具优势(50%)。35% 的后代花朵颜色较深,与雌性亲本的花斑图案相吻合,这表明雌性亲本对 P. pulcherrima 的特征有部分贡献。根据九个质量特征,后代被分为五个不同的组。三个后代,即 D829-4、D829-6 和 D829-8,被认为比其他后代具有更突出的特征,如花朵上的红褐色斑点更稳定、更对称,代表了哈雷型。这些后代有可能发展成为商业品种。
