Abstract

ABSTRACT Increasing population is equal with food needs. Constraints to fulfill food needs are climate anomalies and disese pests. Helminthosporium oryzae is one of the main disease of paddy. This research aimed to determine lines of paddy wich have high yield potential and resistence of Helminthosporium oryzae. Research was carried out on July, 17th 2019 to Desember, 12th 2019. The research was conducted at Wirowongso Village, Ajung District, Jember Regency and in Jember Technology Laboratory, Jember State Polytech. Research using Non-factorial randomized block design (RAK) and further test Duncan Mutiple Range Test (DMRT). There were 13 treatments and 3 replications. The treatments are UDS 001,UDS 002,UDS 003,UDS 004, UDS 005, UDS 006,UDS 007, UDS 008, UDS 009,UDS 010 and comparison of line of KI 237, varieties of Ciherang and Inpari-30. The yield potential of all treatments are classified as high yield potential. The resistance in the end of vegetative period was classified as resistant in all treatments except the comparison variety Inpari-30 which was classified as slightly resistant. The resistance at the end of flowering in all treatments was classified as slightly resistant, except for the UDS 001 line was classified resistant. The Resistance at the end of grain filling in all treatments was classified as slightly resistant. Keywords : paddy, line, resistance
