Morphological characteristics of Madiun 1, the First Porang (Amorphophallus muelleri Blume) released cultivar in Indonesia

Abstract

Porang (Amorphophallus muelleri Blume) is a tuber crop native to the tropics that belongs to the Araceae family. Porang is a potential tuber crops that has been known in Indonesia for a long time, but the value of its product has not been widely disclosed. The planting area covers over 45,000 ha with East Java as the main production areaMadiun-East Java has a long and the oldest history of porang cultivation in Indonesia and has great potential for porang development. Characterized and officially released its local cultivar as an official released cultivar would protect the local germplasm and can be used as a basis for character improvement. Porang Madiun 1 cultivar has morphological characteristics of compound leaf type, dark green-green leaf color. The color of the leaf edges is pink, but as the age of the plant increases, the leaf edges turn white. Porang leaf surface smooth-wavy, hairless.

“…Of the many porang plants planted and used as food ingredients and industrial materials, only A. campanulatus (Dennst) Nicols is known by a suweg [5]. The development of porang plant cultivation is significant because the plant has a relatively high economic potential [6]. It will be very helpful in improving people's living standards.…”

“…Although the porang plant has great economic value and is a superb export crop featured in the Ministry of Agriculture's TEM program, the problem is the restricted supply of seeds. The government has only issued one variant yet, the Madiun-1 variety, in 2020 [6]. Indobreed Agro Nusantara is IOP Publishing doi:10.1088/1755-1315/1168/1/012057 2 limited, so not all demands for porang seeds can be met.…”

Effect of media type and method of sterilization on growth of porang (Amorphophallus muelleri) shoots in vitro

“…Sexual propagation can be through seeds. Porang plants will produce flowers after three years of planting, which then flowers will develop into fruit or seeds [10,11]. Vegetative propagation can be by bulbs, bulbil and leaf parts [12].…”
