In the course of marker-assessted selection for the blast resistance gene Pi-b, among 372 rice Oryza sativa L. doubled haploids DH0 geterozygous plant was identified. In the offspring (11 doubled haploids DH1), only Pi-b resistance allele was revealed. The reason for the appearance of false heterozygosity is discussed. By analogy with mixoploidy, an explanation is proposed for the phenomenon of somatic tissues mixogeny.

The gene Pi-ar confers resistance to Pyricularia grisea race IB-45 in a somaclone derived from immature panicles of the susceptible rice (Oryza sativa) cultivar Araguaia. RAPD technique was used to identify molecular markers linked to this gene utilizing bulked segregant analysis. Initially, the two parental DNAs from the resistant donor SC09 and 'Araguaia' were analyzed using random primers. Of the 240 primers tested, 203 produced amplification products. The two parental DNAs along with the resistant and susceptible bulks of F2 population were screened using 48 primers that differentiated resistant and susceptible parents. Even though eight primers differentiated the resistant bulk from the susceptible bulk, as well as somaclone SC09 and 'Araguaia', only one primer, OPC02 ('GTGAGGCGTC'), was found to be tightly linked (1.7cM) to the resistance gene of somaclone SC09.
