Karakterisasi Morfologi dan Hibridisasi Rain Lily (Zephyranthes sp.)

Abstract

Rain lily (Zephyranthes sp) is usually used as a landscape ornamental or potted plant. These flowers are limited in color, size, and shape. Genetic variability and variation of color, size, and shape increased through hybridization. The research was conducted at the Indonesian Ornamental Crops Research Institute, from April-November 2021. The research objective was to know the morphological character and seed pod formation of the Rain lily. Some cultivars of Rain lily were used as materials. There were Zephyranthes rosea, Zephyranthes pulchella, Zephyranthes candida, Zephyranthes minuta, and Zephyranthes carinata. The parameters observed were the Rain lily’s morphological character, the seed pod’s harvest time (days), pod diameter (cm), the number of seed formations, and the receptive time of the pistil and anther. Seed pod formation was less among Rain lily parents from their crossing. Approximately seed formation was taking time 22.3 to 27.6 days after crossing. The favorable time of receptive on 07.00 – 10.00 a.m. The average diameter was 1.7–2.1 cm and the number of seeds was about 5.0–19.3.
