RESEARCH CONTRIBUTIONS

 

  • Two ‘Triple disease resistant tomato F1 hybrids’, Arka Rakshak (120 t/ha) and Arka Samrat (100 t/ha), with resistance to Tomato Leaf Curl Virus (ToLCV), Bacterial Wilt (BW) and Early blight (EB) were bred  first time in India and released during 2010 and were well adopted by tomato growers in the country (As PI).  We have also received requests from foreign countries (Vietnam, African countries, Malaysia and Pakistan) for the supply of F1 seeds of both hybrids. 
  • As Co-PI,  I am involved in the development and release of two chilli F1 hybrids Arka Harita: CMS based F1 hybrid with tolerance to powdery mildew (Notified in Gazette-GOI: S.O. 456 (E) dt. 06-03-2012) and Arka Khyati: CMS based F1 hybrid with tolerance to virus. Recommended at Institute level by Varietal and Technology Identification committee during 2011
  • I am involved in the development of thirteen advanced breeding lines (ToLCV+BW+EB resistant and long shelf life) and eleven pre-released F1 hybrids (triple disease resistant hybrids suitable for poly house and open cultivation).
  • Collected more than 300 tomato germplasm lines, evaluated & identified elite lines for yield, quality and resistance to major diseases. Molecular markers linked to ToLCV, late blight & Root Knot Nematode resistance were validated & utilized to develop multiple disease resistant lines & F1 hybrids.
  • In addition to Main Institute projects (4), I have also handled externally funded projects (National-7 and International National-1).   
  • Produced 38 tons of breeder seeds of 51 varieties/hybrids in 23 vegetable crops and earned   Rs. 89 lakhs towards institute resources. Pioneer in initiating a successful seed-village concept in the Institute & produced about 23 tons of seeds of 11 varieties in 6 vegetable crops in farmers’ field since 2010
  • Organized three Inter-national training programmes, four training programmes on PPV and farmers’ rights Act 2001, one symposium and brainstorming session and  twelve field days/field demos and exhibitions
  • Instrumental in the release of  27 varieties including 6 F1 hybrids in 11 vegetable crops as Head of  Division of vegetables (2009-2014) and also established field laboratories under DUS testing and expanded seed processing capacity.
  • Established two Vegetable Field demonstration blocks at IIHR, Bangalore & CHES, Chettalli.
  • Published more than 13 research articles, guided 10 post graduate students, honored with three awards and recognized nationally and internationally in tomato resistance breeding.
  • Mobilized a sum of  Rs. 25 lakhs  by the sale of research materials (advanced breeding lines and parental lines of tomato hybrids Arka Rakshak and Arka Samrat) through ITMU.
