Abstract/ Executive Summary:

Experiments on chickpea genotypes and varieties (CPC-814, CPC-830, CPM-825, CPM-860, BARIsola-3 and Binasola-4) were conducted at two locations (Magura and Nachole) of Bangladesh under pesticide free open field conditions to screen out against pod borer on the basis of physical parameters. The mean pod damage among the test entries ranged from 8.3-15.2% in Magura and 13.9-16.6% in Nachole. The physical characteristics i.e. number of branches plant^-1 , number of leaves branch^-1, number of pods plant^-1, number of infested pods plant^-1, hundred seed weight (g), grain yield (t ha^-1), trichomes density cm^-2 area of pod shell were recorded and analyzed. A significant positive relationship of pod borer infestation with the number of branches plant^-1 and negative relationships were observed with the number of trichomes on pod shells and among the genotypes CPC-814 showed the best performance against pod borer.

Keywords: Chickpea, Pod borer (Helicoverpa armigera), Physical parameter

Location: BINA sub-station farm, Magura and farmer’s field at Nachole, under the district of Chapainawabganj

Start Date: 00-10-2006

End Date: 00-03-2007

Program Area: Variety and Species

Commodity: Chickpea

Objectives:

1. To evaluate chickpea mutants developed by BINA against pod borer on the basis of their some physical characters at two different locations of Bangladesh.

Methodology:

The experiments were conducted at BINA sub-station farm, Magura and farmer’s field at Nachole, under the district of Chapainawabganj during October 2006 to March 2007. The experiment was laid out in a randomized complete block design with 3 replications at both the locations having plot size 3 m X 1.5 m. The chickpea seeds of two varieties (Binasola-4 and BARIsola-3), two mutants (CPM-825 and CPM-860) and two cultivars (CPC-814 and CPC-830) were sown in rows made by hand plough on 28 November 2006. The distance maintained between row-to-row and seed to seed were 30 cm and 15 cm, respectively. Seeds of all varieties, mutants and cultivars were collected from Bangladesh Institute of Nuclear Agriculture, Mymensingh. Germination test was done in the laboratory before sowing in the field. Different intercultural operations were accomplished as and when necessary for better growth and development of the plants. Seed and straw yield were recorded plot wise after drying and was calculated to t ha^-1. The plots were harvested separately at the stage of 70-80% pod maturity stage. Before harvesting the crops at both the locations, 10 representative plant samples from each plot was collected separately, tagged properly and bought to the laboratory for studying the physical parameters like branches plant^-1, leaves branch^-1, pods plant^-1, infested pods plant^-1, 100 grain weight, trichomes density cm^-2 area of pod shell and grain yield (t ha-1). The data were analyzed statistically by F-test. Analysis of variance was done with the help of computer package M-STAT. The mean comparisons of the treatments were evaluated by DMRT.

Achievement/Findings:

It could be concluded that no chickpea genotypes or varieties were 100 % resistant against pod borer infestations and the pod infestations of chickpea by chickpea pod borer had a positive correlation with number of branches plant^-1 but a negative relationship with trichome density cm^-2 area of pod shells. CPC-814 comparatively showed the best performance among the test entries irrespective of grain yield, infestation, trichomes density on pod surface and other parameters.
