Development of multiple resistance in chilli pepper

Abstract

A number of chilli pepper cultivars from indigenous as well as exotic material were screened against fungal fruit rot and die-back caused by Colletotrichum capsici wet rot caused by Choanephora cucurbitarum and viral mosaic caused by TMV CMV and tobacco leaf curl diseases. Among these a few Indian lines Perennial Surjamani BG-1 Longi and Lorai possessing multiple resistance were isolated. These lines being poor yielder or having small fruit size were crossed with commercial susceptible cultivars posessing good horticultural traits which lead to the development of a new line S 118-2. On the basis of its good performance in yield and disease resistance it was released under the name 'Punjab Lal' for cultivation in Punjab State India in 1985. Now a number of new lines possessing multiple resistance are being developed through introduction selection and hybridization programme at Punjab Agricultural University Ludhiana. A yield trial comprising of 24 lines 21 resistant and 3 susceptible was conducted in 1988-89 to test against 5 diseases fruit rot dieback wet rot mosaic and leaf curl virus under field conditions. On the basis of pooled mean score analysis against disease the lines BG-1 MS 13 and CH-1 were found highly resistant to all diseases. These were closely followed by S20-1 MF41-1 Laichhi-2 LS-1. The moderately resistant were LS III LS IV Punjab Lal MS 12 x LLSF1. Tiwari I Surjamani Pant C-1 Indonesian Selection HS2 and Laichhi-4. The lines MS 12 x LLSF1 LS III LS IV and LS I possessing moderately resistant/tolerant produced significantly higher fruit yield than commercial cultivar and were considered outstanding
