Studies were conducted in the field and greenhouse at
the Philippine Rice Research Institute, Maligaya and in the
International Rice Research Institute (IRRI) from June 1991
to April 1993 to determine the inheritance of WC-traits
identified in several WCVs at IRRI and the allelic
relationship with WCV possessing identified genes.
WC-trait for pollen and spikelet fertility was found to
be controlled by a single dominant gene. WC-genes of BPI 76
(P); Moroberekan; Palawan; IR47686-5-10-B; IR47699-29-6-10;
N 22 and Lambayeque were allelic to WC-gene of Dular but
non-allelic to S5h possessed by Norin PL 9, while WC-genes
of Calotoc and Fossa HV were allelic to Norin PL 9 but nonallelic to Dular.
Incorporation of the identified WC-gene from Norin PL 9
and Dular in the genetically diverse Indica and Tropical
Japonica parental lines can result in developing
Indica/Tropical Japonica hybrid rices.
