Plant phenomics is a high-throughput path-breaking area that meets all the requirements for the collection of accurate, rapid and multi-faceted phenotypic data. Plant phenomics is an approach to envisage complex traits that are appropriate for selection, and provides relevant information as to why particular genotype can stand out in particular environmental conditions. The technique of plant phenotyping can be operated in various dimensions, from the gene to the whole-plant level under a specific environment, and management practices. Through this review, we discuss the recent advances in plant phenomics, highlighting different field and confined high-throughput technologies for utilization in forward and reverse genetics. These plant phenomics technique are very relevant in stress identification, study physiological processes, rapid and efficient screening, dissection and confirmation for understanding the genetic basis of different traits, genes and aspects. Highthroughput phenomics technologies are essential to avoid human error and to reduce time consumption while phenotyping large germplasm populations, or for confirmation of gene or trait functional analysis.

1. Introduction The commonly used traditional phenotyping tools are generally low-throughput and labor-intensive. On the other hand, the use of next-generation genotyping and phenotyping technologies is advantageous over conventional breeding programs as these are rapid, accurate and help in accelerating crop breeding programs. Increasing yields under the vertical intensification scenario will involve novel approaches at the molecular level and plant breeding will boost both productivity and resource use efficiency. Under varied climatic conditions, development of novel and superior cultivar is of foremost importance, requiring assessment of thousands of breeding lines and this can be achieved by

rapid and precise phenotypic assessment. Recent developments have identified phenomics as a pathbreaking area to meet all the requirements that can be acquired with the help of high-throughput phenotyping (high-dimensional phenotypic data). The use of highthroughput plant phenomics approaches may useful to predict the composite characters that are associated (forward phenomics), and in addition, it provides information as to why particular genotypes/germplasm/line are distinct for a definite climatic condition (reverse pho
