Introgression of the rice blast resistance genes Pi1, Pi2 and Pi33 into Russian rice varieties by marker-assisted selection

Published on May 29, 2018 02:47 AM

Marker-assisted selection (MAS) was adopted for
introgression of broad-spectrum blast resistance genes
Pi1, Pi2 and Pi33 into elite Russian rice varieties. It was
shown that microsatellite markers RM 224, RM 527 and RM
310 may be effectively used to transfer Pi1, Pi2 and Pi33
genes into selected Russian genotypes of rice. Based on
the highly productive variety Kuboyar, we obtained the
lines, 200-5668 (Pi 1+2+33 IL14 × Kuboyar), 207-5671 (Pi
1+2+33 IL28 × Kuboyar) and 208-5674 (Pi 1+2+33 IL28 ×
Kuboyar) carrying three pyramided genes Pi1, Pi2 and Pi33
in homozygous state. The lines 200-5668, 207-5671 and
208-5674 are used as an improved resistance donor source
to obtain hybrids and pyramiding additional Pi genes in
order to provide stable long-term resistance for rice blast
disease.
