ANGGI YUDA PRATAMA : Pertumbuhan dan Produksi Bawang merah
(Allium ascalonicum L.) Lokal Samosir Generasi ke Lima (M1V5) Hasil Iradiasi
Sinar Gamma di Dataran Rendah di bimbing oleh ASIL BARUS dan MARIATI.
Penelitian ini bertujuan untuk mengevaluasi pertumbuhan dan produksi bawang
merah lokal samosir pada generasi ke lima (M1V5) hasil iradiasi sinar gamma.
Penelitian ini dilaksanakan di jalan Danau Tempe KM 18 Binjai mulai bulan
Januari sampai Maret 2016. Percobaan ini menggunakan rancangan acak
kelompok non faktorial dengan perlakuan genotip mutan dari berbagai dosis
iradiasi sinar gamma yaitu 0, 1, 2, 3, 4, 5, dan 6 Gy. Parameter yang diamati
adalah panjang tanaman, jumlah daun, jumlah anakan, jumlah umbi, diameter
umbi, bobot segar umbi dan bobot kering umbi. Data yang dianalisis
menggunakan program microsoft excel. Perlakuan yang berpengaruh nyata
dilanjutkan dengan uji beda rataan. Hasil penelitian menunjukkan genotip mutan
berpengaruh tidak nyata terhadap semua parameter kecuali pada bobot segar
umbi dan bobot kering umbi. Bobot segar dan bobot kering umbi tertinggi
dihasilkan genotip mutan yang diturunkan oleh populasi dengan dosis 4 Gy yaitu
34.04 g dan 30.49 g serta lebih besar 43.93 % dan 47,93 % dibandingkan dengan
tanaman kontrol secara berurut.

ABSTRACT
ANGGI YUDA PRATAMA: The Growth and Yield of fifth generation Local
Samosir shallot (Allium ascalonicum L.) treated by gamma rays at lowland
supervised by ASIL BARUS and MARIATI. The aim of the research was to
evaluate the growth and yield of local samosir shallot treated by gamma ray on
M1V5 generation. This research was conducted at Danau Tempe KM 18 Binjai
began January - March 2016. The experiment is using a non-factorial randomized
block design with mutant genotype treatment of various doses of gamma ray
irradiation was 0, 1, 2, 3, 4, 5, 6 Gy. The observes parameters were plant length ,
number of leaves , number of tillers , bulb number , bulb diameter , bulb fresh
weight , and bulb dry weight after twice harvesting. The data were analyzed using
Microsoft Excel program. Treatments were significantly different followed by the
average difference test The results showed that all parameters observed were not
significantly affected by mutant genotype except for fresh weight and dry weight
of bulb after twice harvesting. The highest bulb fresh weight and dry weight were
resulted by genotype mutant irradiated by 4 Gy i.e 34.04 g and 30.49 g which
were more weight about 43.93% and 47.93% respectively compared to control .
