Wild Musa Species Collection of Purwodadi Botanic Garden: Inventory and Its Morpho-taxonomic Review

Abstract

Indonesia, being part of the center of origin of bananas (Musaceae), has a large number diversity of bananas both wild seeded species and edible seedless cultivated varieties. Inventory of wild Musa species in Purwodadi Botanic Garden has been conducted through compiling data records from PBG's Registration section, field inspection and observation to living collections in the garden, herbarium specimens and literature studies. The results show that total 17 wild Musa accessions has been recorded planted in Purwodadi Botanic Garden since 1990 until 2012; comprises of 8 Musa acuminata sub species, 2 Musa balbisiana forms, 1 Musa ornata, 1 Musa troglodytarum, 1 Musa borneensis and 4 unidentified species Musa spp.; but only 8 living accessions remained in 2012. Morpho-taxonomic review of those 8 wild Musa accessions remained will be discussed in this paper including their geographical distributions. According to its differentiated morphological characteristics observations, it is known that there are three accessions were resembled cultivars and one unidentified species have been determined its species level, so that their registration identity needs to be revised. It is important next to prioritize ex-situ conservation of wild Musa species not yet collected in Purwodadi Botanic Garden especially from Eastern Indonesia.

Spore germination and early gametophyte development of Platycerium wandae (Polypodiaceae) from Papua, Indonesia

“…Some living banana plants in the form of suckers, and seeds of wild bananas were collected for ex-situ conservation in Purwodadi Botanic Garden, Pasuruan, East Java, Indonesia. Further identifications of genomic group and sub-group of recorded bananas were confirmed using references available, including Simmonds (1959), Espino et al (1992), Jumari and Pudjoarinto (2000), Valmayor et al (2000), Daniells et al (2011), Hapsari et al (2015b, Hapsari et al (2015c). Online resources were also used: Banana cultivar checklist (http: //www.promusa.org/ Banana+cultivar+checklist) and Musa Germplasm Information System/MGIS (http: //www.cropdiversity.org/mgis/).…”

Clustering Analysis and Genome Inference of Pisang Raja Local Cultivars (Musa spp.) from Java Island by Random Amplified Polymorphic DNA (RAPD) Marker

“…Pisang Raja cultivars were originated from several districts of Java Island, consisting of 8 cultivars from Central Java, 4 cultivars from East Java, and 1 cultivar from Jakarta (Table 1). The genomic group of each Pisang Raja cultivar was previously identified morphologically based on minimal descriptor for bananas (Simmonds, 1959), according to information from the curators, and also from some references (Jumari & Pudjoarinto, 2000;Sukartini, 2007;Wahyuningtyas, 2009;Hapsari, 2014;Hapsari et al, 2015b, Nedha et al, 2017. It comprised of AAA, AAB and ABB genomes (Table 1).…”

Karakter Morfologi Dan Anatomi Pisang Diploid Dan Triploid

“…Terdapat perbedaan karakter warna pseudostem, tipe petiole, bentuk jantung pisang, bentuk ujung braktea, bentuk ujung tepal bebas, dan bentuk ujung buah antara M. balbisiana pada penelitian ini dengan M. balbisiana di Jawa dan Sulawesi. Warna pseudostem M. balbisiana di pulau Jawa berwarna hitam-keunguan dan hijau, tipe petiole margin overlapping, bentuk jantung pisang ovoid, bentuk ujung braktea membulat dan terbelah, bentuk ujung tepal bebas triangular atau seperti jarum, bentuk ujung buah runcing (Hapsari, 2014). Pseudostem M. balbisiana di Sulawesi berwarna coklat keunguan, tipe petiole curved inward, jantung pisang berbentuk ovoid, bentuk ujung braktea intermediate, bentuk ujung tepal bebas triangular, dan bentuk ujung buah tumpul (Sulistyaningsih et al, 2014).…”
