Abstract

Penelitian mutasi induksi untuk perbaikan sifat tanaman ubijalar varietas sari telah dilakukan di PATIR — BATAN. Telah diperoleh 4 galur mutan generasi M1V5 ( D15.7.5; D15.7.7; D15.7.8; dan D15.7.9 ) hasil iradiasi stek batang cv. Sari dengan dosis 40 Gy. Galur-galur tersebut telah ditanam di 4 lokasi yang berbeda yaitu Propinsi Jawa Barat ( Bogor dan Kuningan ) dan Propinsi Jawa Timur ( Malang dan Mojokerto ). Galur mutan, c.v. Sari dan kultivar lokal sebagai pembanding ditanam pada jarak tanam 0,25 x 1 mpada plot berukuran 4 x 5 m. Panen dilakukan setelah tanaman berumur 4 bulan kemudian dilakukan analisis kandungan gula dan pati dari umbi dengan menggunakan alat Spektrofotometer. Hasil penelitian menunjukkan bahwa produksi umbi tertinggi 44,11 ton/ha ditemukan pada galur D15.7.5 di lokasi Mojokerto. Galur tersebut juga stabil pada keempat lokasi uji dengan hasil rata-rata 30,04 ton/ha. Mojokerto merupakan lokasi terbaik dibandig 3lokasi lainnya. Kadar pati bahan kering dicapai 96,47 % pada galur D15.7.9, sedang kadar gula tertinggi diperoleh 8,80 % pada galur mutan D15.7.5. Semua galur mutan berproduksi, berkadar pati dan gula lebih tinggi dibanding tanaman induknya.

Abstract

Shoots of sweet potato Sari variety were irradiated at the doses of 0, 10, 20, 30 and 40 Gy. Irradiated shoots were planted and selected to obtain better mutant lines than that of the parent plant. Ten mutant lines were from the fourth generation which better morphology and productivity than that of the parent plant. The bestproductivity was found at mutant line number 40-2 which was 717.50 g/plant compared to parent plant with 622.50 g/plant. The highest glucose and starch content obtained were at the dose of 20 Gy which were 8.85 and 28.56 %respectively. The mutant line of Sari sweet potato has a potential to produce bioethanol. The bio-ethanol production from those of mutant lines at a range of 15.02 to 19.46 % compared to 13.67 % in the parent plant. The mutant line number 20 was the best line to produce bio-ethanol. The aim of this experiment was to find mutant lines having potential to produce bio-ethanol
