During the meeting in Arlington, USA in 2001, the scientists grouped in PROMUSA agreed with the launching of the Global Musa Genomics Consortium. The Consortium aims to apply genomics technologies to the improvement of this important crop. These genome projects put banana as the third model species after Arabidopsis and rice that will be analyzed and sequenced. Comparing to Arabidopsis and rice, banana genome provides a unique and powerful insight into structural and in functional genomics that could not be found in those two species. This paper discussed these subjects-including the importance of banana as the fourth main food in the world, the evolution and biodiversity of this genetic resource and its parasite.

Berbagai karakter biologi dangenetik pisang menyebabkan pemuliaan tanaman ini melalui persilangan sangat sulit, lama dan mahal untk dilakukan. Di lain pihak kebutuhan sangat mendesak akan kultivar pisang tripoid baru yang tahan terhadap penyakit, khususnya penyakit layu Panama dan Sigatoka. Teknik induksi mutasi in vitro dan variasi somaklonal bersifat langsung sehingga sangat efisien dalam mempercepat pengembangan tanaman ini. Perubahan karakter yang diperoleh melalui kedua teknik ini dapat meliputi hanya satu karakter saja tanpa merubah genotip, baik yang telah ada pada tanaman sebelumnya. Keberhasilan mendapatkan klon dan mutan baru dengan karakter yang menarik mempergunakan kedua teknik di atas tidak terlepas dari dukungan kemajuan metode kultur jaringan. Perubahan genetik yang terjadi dapat terfiksasi pada tiap tahapan subkultur − pada saat yang bersamaan − plantlet dapat diperbanyak untuk evaluasi. Karakter baru yang diperoleh juga terbukti stabil dan diwariskan pada generasi berikutnya. Tulisan ini mengulas latar belakang dan kemajuan pemuliaan pisang di dunia yang diperoleh melalui teknik induksi mutasi in vitro dan variasi somaklonal. Berbagai contoh keberadaan mutan dan klon pisang baru yang diperoleh disajikan beserta latar belakang pemuliaannya.

SINAGA, N. I., MEGIA, R., HARTANA, A., KEIM, A. P. Ecology and distribution of Freycinetia Gaud. (Pandanaceae; Freycinetoidea) in Indonesian New Guinea. Reinwardtia 13(2): 189-197. - The study mainly concerns with the species of Freycinetia that occurs in the Indonesian New Guinea, including the provinces of Papua and Papua Barat. The study indicates that almost all species of Freycinetia in the Indonesian New Guinea prefer high humidity and abundantly occur along rivers, except for the members of the group of species with imbricate leaves, which inhabit also secondary forests. Futhermore, the members of this group have never been found within the range of 1700 to 3000 m altitudes. This highest range of altitudes is specifically occupied by the members of the groups of species with semi imbricate and grass-like leaves. The costal forests are inhabited by the groups of species with semi and non imbricate leaves. Indonesian New Guinea shares many species with Papua New Guinea, except for the members of the group of species with semi imbricate leaves, which are more common in Indonesian New Guinea than in Papua New Guinea. On the contrary, the members of the group of species with grass-like leaves are more common in Papua New Guinea and becoming rare toward the Indonesian site and becoming absent in the Vogelklop (Bird's head), except for F. polyclada which is commonly found in Sorong. Indonesian New Guinea possesses 34 species exclusively distributed in the area, while Papua New Guinea has 72 species. The two areas share 52 species. Only five species have extra New Guinean distributions, i.e. F. excelsa, F. funicularis, F. marginata, F. percostata, and F. scandens
