Characteristics of the new Oriental lily cultivar Yahe
The Oriental lily 'Yahe' (see color photo on the inside back cover) was bred using Oriental lily 'CoAmore' as the female parent and 'Acapulco' as the male parent, through the independently developed patented technology (ZL03153342.6) "Lily Triploid Breeding Method". In 2006, it passed the new variety protection examination and was announced by the Ministry of Agriculture of the People's Republic of China. Variety characteristics
When the bulb of 'Yahe' is 12-14 cm, the plant height is 80-95 cm, the leaves are lanceolate, the number of leaves is 53-61, and there are 5 veins (the upper surface is flat, the lower surface is raised). The average leaf length is 11.69 cm, and the leaf width is 2.60 cm. There are 6 tepals, 6 stamens, and 1 pistil. The average flower diameter is 18.69 cm, and the number of flower buds is 3-5. The fragrance is strong, the flower is pink, the flower center is bright yellow, and the stigma is milky white. There are very few spots at the base of the petals, averaging no more than 40, and the spots are red. The average vase life of a single flower is about 8 d. The capsule is long elliptical, dehiscing into 3 locules. Most seeds have no embryo, are flat, have a membranous wing, and are semicircular. It differs greatly from the male parent 'Acapulco', mainly in flower color, stigma color, and number of spots. It differs from the female parent 'CoAmore' mainly in flower color, stem color, and number of spots. At the same time, the bright yellow flower center is significantly different from both parents. Key cultivation techniques
It is suitable for cultivation in temperate or high-altitude areas such as Yunnan and Guizhou. In tropical areas such as Guangdong, Guangxi, and Hainan, it can be planted in winter. Protected cultivation with heating and cooling equipment is not subject to the above restrictions. The cultivation substrate needs to be loose, with low salt content (EC less than 1.5), and pH 5.5-6.5. The optimum growth temperature is 20-25°C during the day and 10-15°C at night. Heating is needed below 8°C, and cooling is needed above 30°C. The relative humidity is 60%-80%, and the light intensity is 50000-60000 lx. The planting depth is 6 cm in winter and 8 cm in summer. Start fertilizing when the roots grow to 1-2 cm, once a week, with the same fertilizer types and amounts as conventional varieties. Use conventional methods to control pests and diseases. Use shoot tip culture and high-temperature treatment for virus elimination, and propagate on a medium without plant growth regulators and with high-concentration sucrose. Bulb propagation and postharvest handling are the same as for conventional varieties.
