Variability analysis and evaluation for major cut flower traits of F1 hybrids in Lilium brownii var. colchesteri

Abstract

The characteristics of Lilium brownii var. colchesteri are not found in other lily species. This study analyzed twelve genotypes (F1 hybrids) of L. brownii var. colchesteri for nine important cut flower characteristics. As part of pre-breeding, the variability analysis task for the studied traits was carried out in a randomized complete block design with three replications. The analysis of variance (ANOVA) analyses demonstrated significant variability among the genotypes for the studied cut-flower traits. The higher values of the phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV), coupled with higher heritability, along with the genetic advance expressed as a percentage mean (GAM), revealed that plant height, leaf length, leaf burn, and flower diameter had demonstrated the prevalence of the additive type of gene action. The remaining cut flower traits, especially leaf width, number of flowers, length of outer tepal, the width of outer tepal, and days to flowering, proved to have a prevalence of the non-additive type of gene action. The mean performance of the cut flower traits provides information for effective progeny selection after hybridization. The performance of Ryunghoehyeon had been found to be outstanding for plant height, flower diameter, length of the outer tepal, width of the outer tepal, days to flowering, and the number of flowers.

Phenotypic Variation in Flower Color and Morphology in the Gerbera (Gerbera hybrida) F1 Hybrid Population and Their Association with EST-SSR Markers

“…Understanding the inheritance patterns of key ornamental traits can provide insights into more effective genetic breeding. The inheritance patterns of ornamental traits in various plants, such as Streptocarpus [ 25 ], Lilium [ 26 ], Chrysanthemum [ 27 , 28 , 29 , 30 ], and Hedychium [ 31 , 32 ], have been examined. The study of floral trait inheritance patterns in Asteraceae ornamental plants is a popular research topic, with the inheritance patterns of several traits, such as flower type, being clarified [ 29 , 30 ].…”
