Yezin Agricultural University

Department of Plant Breeding, Physiology and Ecology, Yezin Agricultural University is undertaking teaching, research and extension in order to complete department mission: to develop quality graduates and strategies for sustainable production of crop through the strengthening of both basic and applied researches in crop variety improvement.

To become an internationally recognized department of excellence for education, training and research in crop variety improvement.

 To train students for applying plant breeding, genetic engineering, physiology, plant genetic resources and plant ecology principles to crops and cropping systems in order to increase their efficiency.
 To solve the changing problems in modern crop development, production and management under climate change.
 To transfer of technology to create awareness by organizing training programs, front line demonstrations and study tours for the benefit of the farming community.

Academic Program

Department of Plant Breeding, Physiology and Ecology close attention to development in international education and have contributed four degree programs: undergraduate, post-graduate diploma, master and Ph.D. With the linkage between lecture and practical, department is offering the different subjects including plant taxonomy, plant morphology, plant anatomy, plant physiology, cytology, plant genetics, principal of plant breeding, plant genetic resources conservation, molecular plant breeding, methods of plant breeding, stress plant physiology, sustainable agriculture etc.

Research Area

Crop Breeding, Quantitative genetic analysis, Breeding for physiological traits in Rice and Mung Bean

Current Research

  • Root Characterization, Pod Maturity Synchronization and Pod Shattering rate of Mung bean Genotypes
  • Inheritance of Seed Color in Mung Bean
  • Effect of Leaf Extract from Bougainvillea on Cure of Yellow Mosaic Virus in Mung bean
  • Evaluation, Hybridization and Selection of Mung bean lines for Yellow Mosaic Virus Disease Resistance
  • Assessment of Indigenous Chili (Capsicum annum) varieties upon their physiological traits
  • Comparative Study on Yield and Yield Component Characteristics of Introduced Hybrid and Inbred Genotypes in Rice

Research Program

During 2017-2018 Fiscal Year, department of Plant Breeding, Physiology and Ecology is doing researches mainly focusing on rice crop in order to fulfill the food sustenance of Myanmar. In order to produce new promising lines, the following researches have been leading.



Research title Leader


1. Evaluation of Yield and Yield Component Characters in Promising Recombinant Inbred Rice Lines (F10) Selected by Pedigree Method Daw Nant Nyein Zarni Naing This research training undertook yield trail among the YAU promising lines in comparison with parental lines and local standard varieties. The best varieties adapted to local climatic areas have been selected after intensive yield trail. However it is necessary to conduct further studies in different experimental stations with different environmental background. The students have been well trained how to determine yield and yield components characters, data analysis and steps in varietal selection program via this study.
2. Evaluation of Yield and Yield Component Characters in Promising Recombinant Inbred Rice Lines (F10) Selected by Bulk Population Method Daw Phyu Phyu Maung
3. Evaluation of Yield and Yield Component Characters in Promising Recombinant Inbred Rice Lines (F10) Selected by Single Seed Descent Method Daw Tin New Win
4. Chlorophyll content and its association with leaf photosynthesis in Rice Daw Aye Nyein Chan From this study, it has been determined the amount of chlorophyll at different growth stages in rice. It was observed that the higher the chlorophyll content, the greater photosynthesis rates which contribute the higher yield finally. The students have been trained how to use experimental materials such as SPAD meter and spectrophotometer and photosynthesis meter as well as designing experiment, analyzing data and writing papers through this study.
