Sesame Germplasm Field Day held on 11.04.2017 (Tuesday)

ICAR-National Bureau of Plant Genetic Resources (NBPGR), Regional Station, Hyderabad organised a field day in collaboration with ICAR-Indian Institute of Oilseeds Research (IIOR), Hyderabad on 11.04.2017. A total of 23 scientists of sesame working group representing IIOR, Acharya NG Ranga Agricultural University (ANGRAU), Professor Jayashankar Telanagana State Agricultural University (PJTSAU) and NBPGR attended the programme. A total of over 1500 accessions on display at IIOR experimental farm and 256 accessions at NBPGR Regional Station respectively, for the benefit of sesame working group. A discussion held after the two field visits in which Dr. B. Sarath Babu, Officer-in-Charge presided and Dr. A. Vishnuvardhan Reddy, Director, IIOR, Hyderabad acted as Chief Guest. Dr. N. Sivaraj briefed the gathering on sesame germplasm accessions kept on display at the Regional Station experimental farm. Dr Vishnuvardhan Reddy reviewed the on-going sesame crop improvement programmes at the research stations of PJTSAU & ANGRAU. All the participants thanked NBPGR and IIOR for the initiative and actively participated in the discussion.

Some of the key points emerged during discussion are

  • Sesame is an easy crop to develop varieties within 2-3 years. Hence, the working group asked to utilize the enormous diversity kept in the National Gene Bank.
  • Entire collection of Sesame in NGB (10,127 accessions) need to be characterized by the working group within 2-3 years.
  • Germplasm Registration of Sesame for unique traits with ICAR emphasized as there were 4-5 accessions registered so far.
  • Productivity of sesame and top economic traits needs attention as most of the traits are controlled by monogenic dominant genes.
  • Biotic stresses such as Alternaria, Powdery mildew, phyllody and sucking pests in sesame to be worked out in collaborative/mission mode approach.
  • Research on abiotic stress tolerance (salinity, drought, water logging) in sesame is highly warranted for sustainable production.
  • Major breeding objectives expressed by participating working group are a) determinate plant type-uniform plant type/leaf axil maturation b) high seed yield c) non-dehiscent capsule d) pest and disease resistance and e) adaptation to various stresses.
