Ketahanan Beberapa Genotipe Padi Hibrida (Oryza Sativa L.) Terhadap Pyricularia oryzae Cav. Penyebab Penyakit Blas Daun Padi.
Abstract
ABSTRACT
The objective of this research was to study the variance of hybrid rice
genotypes that showed resistance to leaf blast disease caused by Pyricularia
oryzae Cavara and got genotypes refined of the resistance . The research was
conducted at the Department of Disease Laboratory of Plant Pests and Diseases,
Faculty of Agriculture, Univeristy of Brawijaya and in the P.T. DuPont’s research
field in Ketawang Village, Bululawang, Malang since April until June 2012. This
research used Randomized Block Design with 3 replications and 80 treatments.
Eighty-treatments consisted of 24 restorer genotypes, 2 CMS genotypes, 24
hybrid A genotypes, 24 hybrid B genotypes and 6 control genotypes (Maro,
Hipa8, LP27P31, LP27P53, Ciherang and IR64). The results showed that there
were occurrence of intermediate resistance on 24 hybrid genotypes A and B.
Twenty four hybrid A genotypes showed resistance reaction with moderate
classification which was equivalent to IR64 as the best control genotypes.
Key word : Resistance, Leaf blas, Pyricularia oryzae Cavara
