Controlled Environment vs Field Phenotyping Controlled Environment Field Better control of soil moisture and nutrient inputs Difficult to control input application Offseason phenotyping and imposition of biotic stress possible Not possible Accurate data acquisition under desired lighting using variety of cameras Lighting cannot be controlled, shadow effects and influence of wind Cannot immitate natural field conditons -space constraints Natural growth environment of the crop Two approaches : Moving plants along the sensors and Moving sensors along the plants Single approach : Moving sensors along the plants

Applications of speed breeding Speed breeding can greatly accelerate the crop improvement process Can be integrated with other advanced techniques like genomic selection, genome editing, high-throughput genotyping, etc Speed breeding protocols are also being tested by various researchers in other crops like Groundnut and Grain Amaranth to name a few
Experimental outline F 7 bulked RILs derived from IR64 (mega variety) X Aswina (high biomass landrace) cross RILs were planted in three cohorts with stagerred planting dates Plot size adjusted for tractor movement (housing HTP platform) 1516 RILs were genotyped by GBS P henotyped manually and by tractor mounted high-throughput platform
Tractor-based HTP platform Tanger P et al (2017) Sci Rep 7 :42839 doi:10.1038/srep42839
Manual and HTP data collection Summary of HTP data collection HTP Traits : Plant height, NDVI, NDRE, Chl a and Canopy temperature depression Manual data collection at 80 DAS and above – Days to heading, Plant height, Biomass, Grain yield (cohort 3)and Harvest index ( cohort3) Tanger P et al (2017) Sci Rep 7 :42839 doi:10.1038/srep42839
The NDVI effect size of QTL [email protected] (Chromosome#@ cM ) Tanger P et al (2017) Sci Rep 7 :42839 doi:10.1038/srep42839
Manually-measured traits are genetically correlated with HTP traits across QTL Tanger P et al (2017) Sci Rep 7 :42839 doi:10.1038/srep42839
Significant findings of Tanger et al (2017) D etecting QTL with HTP phenotyping is accurate and effective Genomic regions controlling yield and yield components can be identified nondestructively and in a fraction of the time F ield based HTP allows efficient screening of large populations HTP can offer rapid, early prediction of phenotypes leading to better selection of lines
