Karakter Vegetatif dan Generatif Beberapa Varietas Padi (Oryza sativa L.) Pada kondisi lahan Cekaman Besi (Fe). Vegetative and Generative Characters of Several Rice Varieties (Oryza sativa L) Resistant to Iron Gripping. Supervisor: Dwi Rahmawati. Deni Fitri Stiyawati Seed Production Technique Study Program Agricultural Production Department ABSTRACT The plantation growth is influenced by several factors, consist of: the sun light, the air, and the soil. The soil is the intermediaries to provide those factors except the sun light. This study used planting media containing the high level of iron, which was 253 ppm of marshland taken from Sumberejo village, Ambulu – Jember. The iron was reduced in the soil. The high level of iron could be poisoning the plantation growth. This condition could be the main obstacles on rice production activity especially on marginal area. This study used seven rice varieties: Inpari variety 13, Sintanur, Towuti, Mekongga, IPB 3S, IR64, and Ciherang. All varieties were resistant to the iron gripping (Fe) or no gripping on 253 ppm of iron containing. This was shown to the short plant life and the maturity of plant which was 100 – 116 days, the plant height; including short and medium size, between 100,58 – 123,96 cm, the potential result 8 - 10 ton per hectare, qualitative characters of vegetative and generative phase, showing the morphology character and plant result based on the planted variety description. Then, it could be designed directed physiology-based rice plantation breeding program by using the results of the crossbreeding in this study that create the new strains which are resistant to the iron poisoning and get the high production.
