Repeated screening and validation of heat tolerance For repeat screening, 98 lines of JHN mutants (M 5) with high spikelet fertility (> 80%) were treated at high temperature (40 ºC to 45 ºC ) under the same conditions as in the preliminary screening. The experiment was started in 2013 (April–May) and set ...

Screening rice genetic resources for heat tolerance.

Rice is sensitive to high temperature, especially at the reproductive stage, which causes spikelet sterility and yield losses. To identify heat-tolerant genetic resources for future genetic studies and breeding, we screened 455 IRRI Genebank accessions from hot rice growing regions in the field in the hot season, and 200 accessions with high spikelet fertility were selected for phenotyping in...

Crop Science Abstract - Crop Breeding & Genetics Screening ...

Apr 24, 2018· Breeding more heat-tolerant cultivars would stabilize seed yield and open new regions to field production. To support these efforts, we examined a variety of methods for screening large numbers of bean germplasm exposed to heat stress at the vegetative growth stage as opposed to the reproductive stage, which would prolong the screening process.

HEAT STRESS MANAGEMENT IN HOT MINES - CSIR

Heat Tolerance Testing Selection procedures based on heat tolerance were first applied in the South African mining industry by Dreosti in 1935 (7). Dreosti's heat tolerance test was based on the body temperature responses of miners shovelling rock for 60 minutes in a saturated environment of 35 ºC.
