Abstract

Durian fruit is an exotic tropical fruit that has a unique flavor and aroma. Durian fruit is also called the king of fruits are very popular among various societies because of its peculiar taste. This research aimed to identify the morphological characteristic and phylogenetic relationship of durian in Sidikalang and Tanah Pinem district. The research was done at Sidikalang and Tanah Pinem district in November 2016 to February 2017 with survey method using durian descriptor of IPGRI. Sampling technique using purposive sampling with location judgement . The result of research showed that in Sidikalang and Tanah Pinem district there were 25genotipe of durian been identified. The closest relationship is obtained on G14 and G15 originating from Tanah Pinem District with a similarity value of 0,985. The furthest relationship was obtained from G13 and G15 from Tanah Pinem District with the similarity value of 6,115.

Abstract

Kemampuan adaptasi tanaman kedelai [Glycine max (L.) Merr.] generasi M4 terhadap cekaman kekeringan akan mempengaruhi peningkatan produksi. Penelitian ini dilaksanakan di rumah kaca dan lahan penelitian Fakultas Pertanian, Universitas Sumatera Utara, Medan mulai dari bulan September 2017 sampai dengan Desember 2017. Penelitian ini menggunakan tiga populasi tanaman yaitu populasi tanaman kontrol (Anjasmoro), populasi 100 Gray serta populasi 200 Gray pada generasi M4. Analisa data secara statistik karakter tanaman populasi generasi M4 dengan tanaman populasi kontrol (Anjasmoro) dengan uji t menggunakan aplikasi minitab 16. Paramater genetik yang diamati adalah ragam genotipe, ragam fenotipe dan heritabilitas. Hasil penelitian menunjukkan bahwa ada populasi terpilih dari tanaman kedelai [Glycine max (L.) Merr.] hasil iradiasi sinar gamma generasi M4 yang memiliki pertumbuhan yang baik dalam kondisi cekaman kekeringan dengan kriteria jumlah polong berisi, jumlah biji per tanaman dan bobot biji per tanaman yang tinggi terdapat pada tanaman populasi 200 Gray. Nilai duga heritabilitas yang tinggi terdapat pada karakter jumlah polong per tanaman serta bobot biji per tanamana dari populasi 100 dan 200 Gy dapat dijadikan karakter seleksi untuk kondisi cekaman kekeringan.
