Abstract:
To feed the expected 9.7 billion people by 2050 an increase in the rate of crop production is required. Plant breeder and physiologists will have to play an important role in increasing the yield production per area of crops. A major step after germplasm development is selection which is highly depended on the efficiency and precision of plant phenotyping. Precise phenotyping is required for crops plants studied for identification of QTLs and MTAs etc. furthermore crops plants developed through genomics tools still needs to be phenotyped as well. In the past few decades' various experimental designs and statistical methods have been developed to effectively carry out phenotyping mostly in field conditions, which is the best approach but it limited to time, cost and number of genotypes to be studied. Recently with the advances in genotyping such as GBS, to catchup or associate traits with genes, the measurement or estimation of plant phenotypic traits is the main bottlenecks in plant science. Several crops although having been genotyped are being neglected due to these phenotyping issues. With the rapid change in climatic conditions, sever heat waves and frequent droughts is threatening agriculture productivity in many areas, besides these abiotic stresses some areas are witnessing new biotics stresses due to climate change. Great effort is needed to address the existing plant growth limiting factors along with focusing on near future scenarios particularly heat and drought threating agriculture productivity. Recently with advances in the large scale automated of study of plants, also known as high throughput phenotyping the progress of genetic improvement of crops is speeding up. The application of high throughput field phenotyping based on non-destructive image analysis (red, green, blue (RGB), hyperspectral and lidar etc.) of plant traits under controlled condition and speed breeding is revolutionizing plant improvement and agriculture in general.
