Data for "Ozone-tolerant rice for air-polluted environments"

Abstract

Description of dataset This dataset provides data from a project aimed at breeding of ozone tolerant rice lines. The lines were developed by introgressing previously reported ozone tolerance QTL (Frei et al. 2008) into the Bangladeshi elite rice varieties BINA dhan11 and BRRI dhan 28. The genetic markers and genotypes of the resulting lines are documented in the file ‘Sequence and Genotyping’. The different lines were then tested in a greenhouse experiment and field experiment (ozone concentrations, see file ‘Ozone data’). The remaining files present physiological and morphological data of the different breeding lines under control and high ozone conditions.

Abbreviations O3 = ozone ppm = parts per million ppb = parts per billion KASP = Kompetitive Allele-Specific PCR LBS = leaf bronzing score NDVI = normalized difference vegetation index Lic2 = Lichtenthaler index 2 (representing carotenoid/chlorophyll ratio) SC = stomatal conductance PhiPS2 = Quantum efficiency of photosystem 2 of light adapted leaves A = CO2 assimilation rate MDA = malondialdehyde
