Research Accomplishments: 

(During the Period of 2019-2023) 

  1. Two novel pink coloured tuberose lines IIHR-20-1-24 (IC-0642159) & IIHR-20-2-10 (IC-0642162) with high colour intensity and seed setting ability were developed as pre breeding lines
  2. Developed trait specific tuberose lines in single type for garland and concrete extraction, double type for cut flower and dwarf types for pot culture.
  3. Five tuberose lines resistant to Alternaria leaf blight disease was developed
  4. Standardized in vitro direct regeneration and mutagenesis protocol for tuberose
  5. Tuberose variety  Arka Prajwal was registered with  PPV and FRA, New Delhi.
  6. Five gladiolus lines were developed with novel colour, high flower yield, multiplication efficiency and resistance to Fusarium wilt resistance.
  7. Collected, conserved, characterized and documented the germplasm of tuberose, gladiolus and carnation.
Varieties / Technologies Developed: 

 

  1. Tuberose variety Arka Keerthana suitable for garland was developed high flower yield and concrete content
  2. Involved in development of three chrysanthemum varieties Arka Anirudh, Arka Daval and Arka Manohar suitable for pot culture.
  3. Elite genetic stock of tuberose (2 nos.), China aster (1 no.)  and chrysanthemum (3 nos.) were registered with NBPGR, New Delhi for novel traits.
