The study of albino plant formation on rice anther culture is based on the experiences and research conducted by some scientists on rice anther culture in the world. Albino plant is a plant without chlorophyll and, therefore, has no ability to perform photosynthetic process. The plants are usually formed in the tissue culture especially in rice anther culture experiments. The albino plant formation is not desirable due to the fact that it will decrease is not desirable due to the fact that it will decrease the experiments indicated that there is not enough evidence to prove that genotype has a direct effect on the formation of albino plant. Physiological factors are more likely to affect albino plant formation rather than genetical factors. More research is needed to elucidate the problem of albino plant in tissue culture especially rice anther culture. Mohammad Fatchurochim Masyhudi

Panen Padi Mira 1 Lebih Menjanjikan
KUDUS - Bibit padi jenis Mira 1 menjanjikan harapan baru, bagi pemenuhan kebutuhan pangan. Setidaknya hal itu terlihat dari hasil panen raya padi uji coba bibit jenis Mira 1 Fakultas Pertanian (FP) Universitas Muria Kudus (UMK) di Desa Lambangan, Kecamatan Undaan, Kamis (26/6). Jenis bibit Mira 1 adalah salah satu varietas bibit yang dikembangkan oleh Badan Tenaga Nuklir Nasional (BATAN). ”Varietas lain yang dikembangkan di desa Lambangan yaitu, jenis Juwono, Dewa Ruci, dan C Herang,” kata Dekan Fakultas Pertanian UMK, Hendy Hendro HS, M.Si. Dari hasil uji coba penanaman padi hasil kerjasama dengan Himpunan Keurukunan Tani (HKTI) Kabupaten Kudus tersebut dalam 1 hektar sawah bibit Mira 1 dapat menghasilkan panen kurang lebih 10 ton. ”Bahkan ada yang mencapai 11,5 ton,” kata Wariyo, Ketua HKTI cabang Kudus. Menurut Wariyo, padi Mira 1 ini sangat cocok ditanam di daerah Undaan. Secara kualitas, varietas padi Mira 1 ini memiliki rasa pulen dan berjenis umbuk. Jika dibandingkan dengan padi jenis Ceherang, IR 64, Mira 1 lebih potensial. Jenis ini menghasilkan panen yang lebih besar jika dibanding dengan hasil budidaya varietas lain yang selama ini ditanam petani di Kecamatan Undaan. ” Dengan varietas lain, hanya menghasilkan gabah sekitar 7-8 ton per hektare, atau terdapat selisih 2-3 ton hasil panen per hektare, ” jelas Wariyo, yang juga ketua kelompok tani dari Desa Kalirejo. Panen raya padi jenis Mira 1 kemarin ditandai dengan pemotongan perdana oleh Rektor UMK, Prof. Dr. dr. Sarjadi, Sp.PA. (H50-64) Sumber: Suara Merdeka
The equilibrium moisture content of three soybean varieties (Glycine max L.) at the various relative humidity
The aim of this experiment was to study the storage stability of soybean through the study of its equilibrium moisture content at various relative humidity. The soybean varieties used were Lokon, Guntur and Lokal Brebes. The equilibrium moisture content conditions were settled by adsorption static method under room temperature of five levels of water activity (Aw). The experiment was conducted using complere randomized design. The c and n contants were calculated by using Henderson equation. Results of the experiment indicated that there were no difference in equilibrium moisture content as well as c and n constants value among the three soybean varieties. In conclusion the three soybean varieties would have had the same storage stability; therefore they need the same storage sondition to reach optimum storage stability.
