Experiment code Project Path. 2 (b), 2024
Experiment Title Confirmation and maintenance of disease resistant lines
Research Type AICRP on Cotton
Experiment Background  Keep the resistant entries (few bolls of selfed seeds) from the initial evaluation trials (IET) -National trials viz., Br. 02a or b for G. hirsutum varieties, Br. 22 a/b for G. arboreum, Br. 14a for G. barbadense and Br. 32 b after screening against important diseases.  Record resistant entries only for 2-3 important key diseases.  Those lines will be evaluated again next year by the concerned pathologist at his center under field conditions and also tested at hot spot for that particular disease under nursery/ artificial inoculation condition at below mentioned centers to have confirmed final reaction.  Such entries with two years field screening and one year artificial screening data will be kept by Plant Pathologists for use in developing resistant varieties/ hybrids by that center.  The field screening will be considered valid only in those years when at atleast 3 to 4 grade reaction is observed in susceptible checks in screeing trails.

Objective
  • Keep the resistant entries (few bolls of selfed seeds) from the initial evaluation trials (IET) -National trials viz., Br. 02a or b for G. hirsutum varieties, Br. 22 a/b for G. arboreum, Br. 14a for G. barbadense and Br. 32 b after screening against important diseases.
  • Record resistant entries only for 2-3 important key diseases.
  • Those lines will be evaluated again next year by the concerned pathologist at his center under field conditions and also tested at hot spot for that particular disease under nursery/ artificial inoculation condition at below mentioned centers to have confirmed final reaction.
  • Such entries with two years field screening and one year artificial screening data will be kept by Plant Pathologists for use in developing resistant varieties/ hybrids by that center.
  • The field screening will be considered valid only in those years when at atleast 3 to 4 grade reaction is observed in susceptible checks in screeing trails.
  • Artificial Screening Centers:

  • BLB at Surat
  • Alternaria at MPKV, Rahuri
  • Myrothecium at Khandawa
  • Grey Mildew at Dharwad
  • CLCuV & Root rot disease at CICR, Sirsa
  • Fusarium wilt at Pune
