Abstract

Rice production is affected by several environmental factors, such as cold, salinity and drought stress. These unfavourable factors could have a serious impact on germination as well as on later growth, causing many types of damage. Recently, polyploid breeding can offer an alternative opportunity to enhance the yield and abiotic stress tolerance in rice breeding. This article describes some germination parameters of 11 different autotetraploid breeding lines and their parental lines under different environmental stresses. Each genotype was grown in a climate chamber under controlled conditions: 13 °C for 4 weeks in the cold test and 30/25 °C for 5 days in control, salinity (150 mM NaCl) and drought (15% PEG 6000) treatments, respectively. The germination process was monitored throughout the experiment. The average data were calculated using three replicates. This dataset contains germination raw data and three calculated germination parameters, such as median germination time (MGT), final germination percentage (FGP), and germination index (GI). These data may provide reliable support to clarify whether the tetraploid lines can exceed the performance of their diploid parental lines under germination phase or not.
