Keunggulan dan Potensi Pengembangan Sumber Daya Genetik Durian Kalimantan Tengah

Indonesia kaya akan sumber plasma nutfah dan keragaman jenis durian (Durio spp.), namun pengembangannya tidak sepesat Thailand. Hal ini disebabkan tanaman durian belum dikelola secara komersial dan tanaman yang ada umumnya sudah berumur ratusan tahun yang berasal dari perbanyakan generatif sehingga tidak memberikan hasil yang optimal. Untuk mengetahui keunggulan dari keanekaragaman sumber daya genetik durian maka dilakukan observasi dan karakterisasi di beberapa lokasi di empat kabupaten di Kalimantan Tengah dari Agustus 2004 hingga Januari 2005. Kerabat durian yang diobservasi dan dikarakterisasi adalah durian (Durio zibethinus M.), papaken (Durio kutejensis H.B.), kerantungan/taetungen (Durio oxleyanus), dan layung (Durio dulcis). Hasil karakterisasi menunjukkan bahwa karakter buah antarspesies kerabat durian sangat bervariasi. Perbedaan di antara spesies tersebut terletak pada tipe buah, bentuk buah, tekstur kulit buah, panjang buah, warna kulit buah, warna dan rasa daging buah. Musim berbuah dan produksi masing-masing spesies kerabat durian juga bervariasi. Kerabat durian dari jenis Durio (Durio spp.) yang merupakan tanaman asli Indonesia berpotensi dikembangkan
