PENDUGAAN JUMLAH GEN PENGENDALI BENTUK BUNGA KEMBANG KERTAS (Zinniaelegans Jacq)

Abstract

Character flower shape is a very important character in the cut flower business. This study aims to estimate the number of genes controlling flower paper flower shape character (Zinnia elegans Jacq). Field experiment was conducted at Kebun Percobaan Banguntapan Fakultas Pertanian Universitas Gadjah Mada Yogyakarta in February-June 2009. Materials used in this study is a population of M2. Character shapes of flower are divided into two classes flower phenotypes are not pompom and pompom. Data were analyzed with Chi-square test to compare the shape of the flowers. The results showed that the character of the form of interest is controlled by two loci with two alleles per locus. The comparison is 13 no pompom: 3 pompom and gene action is the interaction inhibitors.
