Abstract:

Garden pea is a cool season leguminous vegetable crop with a temperature requirement of 15-23°C, for its optimum growth. Thus, it is mainly grown as a rabi season crop in India. Increased CO2 concentration in the environment has led to global warming. All the seedlings of pea lines were taken in uniformly after 48h and grown in completely randomized design (CRD) block with three replications having twenty seedlings per replication. The experiment was conducted in the laboratory of Division of Plant Physiology and Biochemistry, ICAR- Indian Institute of Horticultural Research, Bengaluru. The standardization studies using 48 h old Azad P-1 seedlings revealed that optimum lethal and induction temperature were 43°C for 3 hours and 30-38°C for 3 hours, respectively. Screening of 32 garden pea germplasm lines using TIR technique resulted in identification of 10 tolerant lines (ArkaUttam, Arka Apoorva, IIHR 544, IIHR 13-1, IIHR 680, PMR 37, Swarna Mukti, KTP 4, and VRPMR 11) with the help of normal Z-distribution.
