Ph.D. in Genetics and Plant Breeding


PhD in Genetics and Plant Breeding is a doctorate level program with 3-year duration in the domain of agricultural sciences with a specialization in Plant Breeding and Genetics. PhD in Genetics and Plant Breeding course aimed at providing in-depth skills and knowledge to the candidates about plant breeding and genetics so, the candidates can take on research activities with precision and confidence in the practical domain. PhD in Genetics and Plant Breeding course is career orienting in nature. Genetics and Plant Breeding a relatively new and rapidly growing field of contemporary biology. The art and science of modifying plant features to create desirable qualities and, as a result, increase the quality of nutrition in human and animal products are covered in the curriculum. Aspirants will largely learn technical techniques for improving varieties and genetic stocks, changing the genetic make-up of plants and developing novel breeding strategies to increase food, feed, and fibre production.

Ph.D.’s in Genetics and Plant Breeding course

Doctoral Courses

After admission the students undergo a set of courses that help them understand the advanced areas of Genetics and Plant Breeding as per the Choice Based Credit System (CBCS) with a total credit load of 75 credits, of which 45 credits are exclusively earmarked for their Thesis Research.


Thesis research

After completing the courses in the first year, the students start their thesis research. Each student is assigned to an experienced faculty, approved by the Dean of School of Post-Graduate Studies, who would guide the student on his/ her choice of research topic for a minimum of two years period.


Research internship

The students are exposed to several scientific events like symposia and conferences. Many are encouraged to have internship training at other institutes for a couple of months, either in India or abroad.

Student Experiences

Myself Indhu S M, Ph.D., scholar from the Department of Genetics and Plant Breeding, TNAU. I joined PhD program during 2018 in a trimester batch. Program comprises course work for three trimesters and six trimesters for research work. During course work period I have undergone 7major courses, in which “Quantitative and Population Genetics” is a foremost important course which thought us to understand the genetic nature of traits in crop improvement and to make selection in crop improvement program. In the same course we were exposed to basic excel to R programming to analyse our experimental data. Another important course which forms the basis of plant breeding is“Crop evolution and management of PGR” where we learnt techniques from collection to storage of germplasm. We were lucky enough to have Ramaiah gene bank which facilitated storage of our pre breeding as well as breeding materials from our research work. In other courses we were taught about advanced techniques in plant selection, biotic and abiotic stress factors and its mechanisms and quality traits for improvement in each of the field crops. Among the 3-specialization courses, the most interesting course was “Harnessing pollination mechanism” where I was excited to know about different kinds of pollination mechanisms over a wide range of crops. Our classroom was well equipped and well ventilated to listen the classes. All of our course teachers were friendly and easily approachable to clarify the concepts. At the end of course work, we were evaluated through qualifying exam. The most enjoyed part of examination systems was my qualifying viva. Presentations and credit seminars were helpful in developing presentation skills and to break stage fear. My research work is on low phytate improvement in maize. Field has been allotted in Department of Millets. I am grateful to the department for facilitating labours for field works. Our labs are well equipped with nanodrop, advanced PCR, SNP genotyping platform, SPEC, NIR for genotyping and biochemical studies.I got experience to frame and execute a research work and publication of the same in peer reviewed journals with the guidance from my chairman and my advisory committee members. Hence in this four year of doctoral program, I gained skills on how to fix, plan and execute a research, data analysis, plant selection at molecular level and biochemical screening techniques in selecting plants for further improvement. In nutshell CPBG is a place where I equipped myself with skills, publications, experiences and confidence to continue my carrier in research.

I Studies my Ph.D. in GPB at CPBG, TNAU during 2019-2022.  During the one year course work period, I gained knowledge in Advanced genomics, Plant Breeding, Biotechnology, Statistical analysis etc., both theoretical and practical.  Especially the biometrical softwares viz., STAR, Plant Breeding tools, IRRISTAT, STRUCTURE, SAS of software learned during practical classed.

            Incase of research work, the experiment conducted in Department of Rice.  The excellent Agronomical practices from sowing to harvest followed and proper post harvesting process followed.  The Rice quality lab, glasshouse facility, grain counter, deep freezing (– 80oC), Molecular lab are available in Rice Department which are I utilized, all the chemicals and equipments required for our research maintained and saturation level.  I did next generation sequencing analysis in my research and the funding was provided from department of Rice for outsourcing. 

            I am trying for Post-doctoral opportunities available in foreign countries.  The knowledge and publication made from the TNAU was very much useful.  The knowledge gained during my Ph.D. helpful to apply ICAR-ARS examinations.
