Pengujian 10 Galur Harapan Padi (Oryza sativa L.) Tipe Baru IPB di Dramaga, Bogor dalam Rangka Uji Multilokasi

Abstract

The experiment was conduted to evaluate production variability and agronomic traits of ten new plant type rice held at Sawah Baru Experimental Field, Dramaga, Bogor in April−August 2014. Experiment using Randomized Completely Block Design, single factor and three replications. The factor was lines which selected from advanced yield trial that have been conducted before (IPB160-F-36-2-1, IPB160-F-36-5-1, IPB160-F-36-25-1, IPB160-F-46-6-1, IPB160-F-54-2-1, IPB160-F-54-3-1, IPB160-F-54-21-1, IPB162-F-10-2-1, IPB162-F-17-1-1, IPB168-F-8-1-1), and two national varieties (Ciherang and Mekongga) as a check. The result showed that line IPB160-F-36-2-1 which productivity is 7.95 ton ha-1 have significantly higher productivity than Ciherang (6.62 ton ha-1) and Mekongga (6.86 ton ha-1). There are lines that have equal productivity from check with good yield components which potential for further development, that lines are IPB160-F-54-2-1 (7.37 ton ha-1) and IPB160-F-54-21- 1 (7.51 ton ha-1)
