In vitro Screening of Chilli (Capsicum anum L.) Genotypes against the Colletotrichum capsici causing Anthracnose of Chilli

An investigation was carried out at experimental block for chilli crops, Vegetable Research Centre, Pantnagar with ten promising genotype of chilli to assess or screen resistance to anthracnose (Colletotrichum capsici) under in lab condition. The experiment was conducted during rabi season of 2018 – 2019 following Completely randomized block design with three replication. Results revealed that among the 10 genotypes tested under in lab condition for screening against C. capsici, six genotypes of chilli including LUCKNOW-1, CHIHYB-11, CHIVAR -7, CHIHYB-8, CHIHYB-13 and Pant C-1 were shown to be moderately resistant having mean lesion length of 1.94- 1.02 cm with PDI of 5.54- 13.49 whereas the genotypes CHIHYB-12 and CHIVAR -2 showed absolutely susceptible reaction having mean lesion length of 2.61 and 2.13 cm with PDI of 27.72 and 31.81 respectively. The genotypes CHIHYB-9 and NISHANT exhibited highly susceptible reaction having mean lesion length of 3.80 and 3.95 cm with PDI of 51.05 and 58.27 per cent respectively. Pant C-1 variety showed least mean lesion length (1.02 cm) with minimum PDI (5.54%) and found to be much better than other varieties. None of the varieties found resistant among these.The genotypes with moderately resistance reaction could be considered as a promising breeding material for development of high yielding anthracnose resistant chilli variety.
