Crossing of Asiatic hybrids for breeding of new lily cultivars.

Abstract

: This study was conducted to breed interspecific hybrids by crossing between Asiatic hybrids for the purpose of cut flower or pot plant. According to results of reciprocal crossing between L. davidii and ‘Conception’, flower color of F 1 appears nearer to that of each male parent but they seemed to be influenced by L. davidii which has side-facing flower position. The characteristic traits of F 1 hybrids obtained from the cross between ‘Tresor’ and ‘Black Out’ is related to female parent ‘Tresor’. Whereas in a cross between ‘Navidad’ and ‘Hironde’, a progeny 122611-4 has the petal spot characteristic similar to the female Asiatic hybrid ‘Navidad’ and male parent ‘Gironde’ influence on the petal color. F 1 hybrid cross ‘Gironde × Red Sensation’ showed parental flower color expression contribution. In addition ‘Gironde’ as parent contributed extensively in imparting flower color in the resulting hybrids. In the above statements, F 1 progenies were more than 40cm in height and the plant height of their parents was over 70cm. Therefore, it is considered that their F 1 progenies are not short if parents have a long plant height. In ‘Kotnali × Tiny Bee’ progenies, 112061-1 progeny expressed orange flower color similar to female while 112061-2 showed yellow flower color same as male. Plant height was 27.7cm and 22.4cm close to 35.0cm of male parent ‘Tiny Bee’. F 1 hybrid of ‘Matrix × Holebibi’ expressed three flower color all of parents. It was dwarf and distinguishable as compared to parental phenotype. Therefore, it is concluded that for potted lily flower development carrying dwarf plant height and intermediate morphological traits Asiatic hybrids plays an important role such as ‘Tiny Bee’ and ‘Matrix’.
