Identifikasi keragaman biji perlu dilakukan agar mendapatkan karakter genotipe tanaman yang berbeda dalam proses perakitan kultivar untuk mencegah duplikasi. Adapun tujuan dari penelitian ini untuk mengetahui karakter dan variabilitas karakter biji bunga matahari. Aksesi tanaman yang digunakan yaitu Ha1, Ha15, Hu1, Hu2, dan Hu3. Metode penelitian ini terdiri atas kegiatan pengolahan lahan, penanaman, perawatan, pengendalian OPT, dan pemanenan bunga matahari. Setelah diperoleh biji hasil panen, dilakukan karakterisasi benih dengan peubah kuantitatif yaitu panjang biji, diameter biji, bobot 100 biji, persentase biji hampa. Peubah kualitatif terdiri atas warna biji, bentuk biji, garis tepi dan warna garis. Analisis data yang digunakan adalah statistik deskriptif sederhana. Analisis data melalui perbandingan varians fenotipe dengan standar deviasi varians fenotipe, varians, standar deviasi. Hasil yang didapatkan pada karakter kualitatif dan kuantitatif menunjukkan adanya keragaman.

Diantara upaya untuk meningkatkan produksi kedelai adalah melalui penggunaan benih bermutu, tetapi keberadaan patogen tular benih sering menurunkan mutu benih. Patogen terbawa benih kedelai yang jarang dilaporkan antara lain adalah bakteri patogen, sehingga perlu dilakukan penelitian yang bertujuan untuk mengidentifikasi bakteri terbawa benih kedelai secara morfologi dan fisiologi dengan metode liquid assay. Benih kedelai yang digunakan pada penelitian adalah varietas Anjasmoro, Detam 4, dan Dering 1. Sebanyak 1000 butir benih dari masing-masing varietas dicuci dengan NaOCl 1% dan dibilas aquades steril. Masing-masing benih ditambah aquades steril dan dihancurkan menggunakan grinder. Ekstrak benih yang diperoleh diencerkan secara berseri dan dituang pada media Nutrient Agar. Koloni yang tumbuh dikelompokkan berdasarkan warna dan dihitung jumlah koloninya. Setiap koloni bakteri dimurnikan pada media selektif King’s B dan Yeast Dextrose Calcium Agar (YDCA). Karakterisasi fisiologi meliputi uji reaksi gram, uji katalase, uji fluoresen, uji oksidase, uji hidrolisis pati, dan uji aktivitas arginin. Hasil penelitian menunjukkan bahwa benih kedelai varietas Anjasmoro memiliki jumlah populasi bakteri yang lebih banyak dibandingkan varietas lain.
