Color inheritance patterns of modern hemerocallis hybrids

Abstract

Genetics of daylilies (Hen1erocallis) has not been well documented. Much is unknown and little has been published about the color inheritance of this popular flower and its many modem hybrids. Because of the lack of publications discussing flower color inheritance patterns, this study had two components. The first was to interview and work with the daylily hybridizers in an effort to learn from them. The second approach was experimental. The experimental study explored patterns of inheritance for color in the offspring of lavender and "near white" modem day lily hybrids. Six lavender hybrids and seven "near white" hybrids were chosen as the parental generation and crossed in all possible combinations to provide adequate F 1 material for analysis. The F 1 generation provided several hundred blooming plants, most of which were a result of the "near white" crossed with the "near white" hybrids. An attempt was made to produce F2 generation plants; however, this caused a severe decline in viability of the F 1 generation plants and was stopped. The resulting plants from the few crosses made were not sufficient in number to provide useful data. Analysis of F1 flower color patterns revealed a multigenic basis for patterns.
