Keragaan galur harapan padi tipe baru (PTB) IPB di Bogor dan Kulon Progo dalam rangka uji multilokasi

Abstract

The objective of the experiment were to test yield potential and identify rice promising lines as part of multilocation yield trial. The experiment was conducted at two locations namely Bogor Regency, West Java and Kulon Progo Regency, D. I. Yogyakarta from January until May 2010. The experimental was arranged by Randomized Compately Block Design with three replications. The experimental consists of eight rice promising lines and two control varieties. The result of the analyses indicated that lines IPB97-F-13-1-1, IPB97-F-15-1-1, IPB97-F-20-2-1, IPB97-F-31-1-1, IPB97-F-44-2-1, IPB102-F-90-1-1, and IPB102-F-92-1-1 have yield were higher than Ciherang (6.764 ton/ha) and IR64 (6.972 ton/ha). Each lines having yield 8.228 ton/ha, 9.309 ton/ha, 8.692 ton/ha, 8.183 ton/ha, 8.222 ton/ha, 7.204 ton/ha, and 8.029 ton/ha recpectively. In addition, the location effected on the appreance of rice promising lines. There were interaction of genetic and environment on plant height, total number of tillers, panicle length, 1 000 grain weight and yield.
