PERFORMANCE OF CHILLI VARIETIES AGAINST CHILLI LEAF CURL VIRUS (ChLCV)

Abstract

Chilli (Capsicum frutescens) is the second most important and widely grown vegetable crop in the world belongs to the family Solanaceae. A field experiment was conducted at the central research field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during October 2018 to March 2019. The study was aimed to evaluate varietal performance of chilli against (ChLCV) and to assess the disease incidence (%) and PDI of Chilli leaf curl virus (ChLCV) among different varieties. In this study, in total 8 varieties were considered viz. BARI-1, BARI-2, BARI-3, Kalomorich, Bograjhal, Bindumashi, Dhanua and Sufia. The field experiment was carried out in randomized complete block design (RCBD) with three replications. All the varieties showed significant influence on different assayed parameters in the test crop chilli under field condition against ChLCV. Among the varieties, three varieties (Bogra jhal, Bindumashi) were found Moderately Resistant, three varieties (BARI-2, BARI-1, Sufia) were showed Moderately Susceptible, two varieties (Kalomorich, Dhanua) were Susceptible. BARI-3 variety was found Highly Susceptible against ChLCV compared to other varieties. Due to chilli leaf curl disease evident morphological changes appeared in leaves, twigs, flowers and fruits. Yield of different chilli varieties was found negatively correlated with the disease incidence (%) of ChLCV. Whereas yield loss of chilli varieties positively correlated with disease incidence (%) of ChLCV. Considering the disease incidence, PDI, growth and yield contributing characters among the chilli varieties it was evident that no resistant variety was found. Whereas, two local variety Bogra jhal and Bindu mashi showed appreciable performance against ChLCV.
