Temperate japonica

Salinity has a significant impact on rice production in coastal, arid and semi-arid areas in many countries, including countries growing temperate rice, such as Kazakhstan. Salinity tolerant temperate japonica rice accessions were identified in this study, these accessions are important resources for breeding programs. SNPs located in the promising QTLs and candidate genes could be used for future gene validation and marker assisted selection.

Rice plants are sensitive to the agro-climate conditions, being photoperiod one of main factor contributing to their adaptation to the region where they are grown. Dissecting the genetic bases underlying diversity in rice populations adapted to specific environmental conditions is a fundamental resource for breeding. In this study we have analysed a collection of japonica varieties adapted to temperate regions to perform association studies with traits of high agronomical interest such as heading date, plant height, number of panicles, panicle length and number of grains per panicle.

Nitrogen fertilization is known to increase disease susceptibility, a phenomenon called Nitrogen-Induced Susceptibility (NIS). In rice, this phenomenon has been observed in infections with the blast fungus Magnaporthe oryzae.

An F2 population derived from a cross between a high salt-tolerance indica variety, TCCP266, and a susceptible elite temperate-japonica Egyptian variety, Sakha102, were produced. We performed QTL mapping for physiological traits related to rice salttolerance. Single plant analysis of each of the polymorphic marker was carried out using randomly selected 288 F2 individuals. 50 polymorphic markers covered four chromosomes of rice (1, 3, 4 and 9). A total of 24 QTL were detected (LOD score > 2.0), which were distributed on the four chromosomes.
