Abstract/ Executive Summary:

An experiment was conducted in different farms of BINA sub-station at Magura and Ishurdi and in the farmers’ field at Nachole upazila of Chapai Nowabgonj and Tetulia upazila of Panchagor during kharif-I to evaluate the performance of sesame mutant lines (SM-5 and SM-12). The tested parameters included: plant height, branches per plant, capsules per plant, seeds per capsule, days to maturity and yield per ha. Highly significant variations were observed both in individual location and combined over locations for all traits except number of capsules per plant in on-station trial. On the other hand, highly significant variations were observed for all traits except capsules per plant in Nachole upazila of Chapai Nowabgonj and combined over locations. The mutant line SM-12 can be registered as a new variety of sesame in respect of higher number of branches per plant, capsules per plant and higher seed yield.

Keywords: Mutant, Sesame, On-station, On-farm

Location: BINA sub-station at Magura and Ishurdi and in the farmers’ field at Nachole upazila of Chapai Nowabgonj and Tetulia upazila of Panchagor

Start Date: 00-02-2008

End Date: 00-05-2008

Program Area: Variety and Species

Commodity: Sesame

Objectives:

1. To evaluate the performance of two newly developed mutants of sesame in the farms of BINA sub-station at Magura and Ishurdi and in the farmers’ field at Nachole upazila of Chapai Nowabgonj and Tetulia upazila of Panchagor districts.

Methodology:

The trials were carried out in the farms of BINA sub-station at Magura and Ishurdi and in the farmers’ field at Nachole upazila of Chapai Nowabgonj and Tetulia upazila of Panchagor during kharif-I of 2008. Two advanced mutant lines (SM-5 and SM-12) and two check varieties (Binatil-1 and Baritil-2) were included in the test. The experiment was laid out in a randomized complete block design with four replications. Unit plot size was 25 m² (5m x 5m) with 25 cm spacing between rows and 8-10 cm between plants in a row. Seeds were sown from the last week of February to 15 March 2008. Recommended management packages were followed for on-station trials while farmers’ practices with recommended doses of fertilizers, one or no irrigation with poor cultural managements were followed for farmers’ field trials. Data were taken for plant height, branches per plant, capsules per plant and seeds per capsule from 10 randomly selected plants of each plot. Days to maturity was counted when 80% capsules were matured and turned into yellowish colour in each plot. Seed yield of each plot was recoded after harvest and then converted into kg/ha. Appropriate statistical analyses were performed and the mean values of each character were compared. Mean differences of different parameters were tested by Duncan’s Multiple Range Test.

Achievement/Findings:

Seed yield, the most important characters in sesame, was significantly difference in both locations. At Nachole, Binatil-1 produced the highest seed yield (1302 kg/ha) followed by SM-12 (1240 kg/ha) whereas Baritil-2 produced the lowest seed yield (1115 kg/ha). At Tetulia, Binatil-1 produced the highest seed yield (1388 kg/ha) followed by SM-12 (1313 kg/ha) where as Baritil-2 produced the lowest seed yield (1194 kg/ha).
