standar pengamatan ini kami buat berdasarkan kebutuhan kami pak. ada beberapa pustaka yang menurut saya relevan, seperti Sugarcane, second edition (Glyn James), Sugarcane Improvemnet through Breeding (Don J Heinz), atau bisa juga baca Pedoman Sertifikasi Bibit Tanaman Tebu (Keluaran Deptan - Direktorat Perbenihan). Semoga membantu.
