Abstract/ Executive Summary:

Significant variations were observed among the genotypes for all the traits except days to maturity both in individual location and combined over locations. Among three lines and check varieties, two lines (BAU-S/70 and AVRDC-73) were produced taller plants (67 - 70 cm) while two check varieties BARI Soybean-6 and Binasoybean-1 were produced shorter plants (47 and 53 cm, respectively). BAU-S/70 was produced the highest number of 68 pods plant^-1 and BARI Soybean-6 was produced the lowest number (53). BAU-S/70 was produced the highest seed yield (2608 kg ha^-1) which was closely followed by AVRDC-78 (2567 kg ha-1) and BARI soybean-6 was produced the lowest yield (2177 kg ha^-1). BAU-S/70 was also produced the higher number of branches and pods plant^-1 along with higher 100-seed weight. Both lines, because of their higher number of branches and pods per plant, higher number of seed per pod and higher seed yield potential can be selected for further trials both at research field to be registered as varieties.

Keywords: Soybean, germplasm, Yield trials, Evaluation, Selection

Location: Experimental field of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, BINA sub-station farm Rangpur, Magura , farmers field Chandpur and Noakhali .

Start Date: 01-07-2012

End Date: 30-06-2013

Program Area: Variety and Species

Commodity: Soybean

Objectives:

To evaluate the performance of three selected promising soybean lines as compared to two check varieties in respect of maturity period, seed yield and yield contributing characters at five different locations of Bangladesh.

Methodology:

Three promising advanced soybean lines along with two check varieties (Binasoybean-1 and BARI Soybean-6) were evaluated through on-station and on-farm trials. The trials were conducted at the experimental fields of BINA Hqs. farm, Mymensingh and BINA sub-station farms at Rangpur and Magura, and farmers’ field at Chandpur and Noakhali during January to April 2013. The experiments were laid out in a randomized complete block design with three replications. Sowing was done within 1st week of January 2013. Spacing between rows was 30 cm and 7-10 cm between plants in a row. Unit plot size was 24.5 m² (5 m X 4.9 m). Recommended production practices including application of recommended doses of fertilizers were followed to ensure normal plant growth and development. Data on various characters, such as plant height, number of branches/plant, number of pods/plant and number of seeds/pod,days to maturity, 100-seed weight were taken from 10 randomly selected plants of each plot. Maturity period was counted when the plant and pods of each plot turned into yellowish brown color and almost all the leaves shed. Seed yield of each plot was taken from the eight middle rows avoiding border effects and plot seed yield was converted into kg ha-1. Appropriate statistical analysis were performed with the mean data of each character. Mean differences of different parameters were tested by Duncan`s Multiple Range Test (Gomez and Gomez, 1984)

Achievement/Findings:

Among three lines and check varieties, BAU-S/70 was produced the highest number of 68 pods plant^-1, highest seed yield (2608 kg ha^-1). BAU-S/70 was also produced the higher number of branches and pods plant-1 along with higher 100-seed weight. Because of the higher number of branches and pods per plant, higher number of seed per pod and higher seed yield potential BAU-S/70 was the best performer followed by AVRDC-78 than the other lines and the check varieties regarding seed yield and yield contributing characters. Results of yield trials indicated that BAU-S/70 is suitable for cultivation in Bangladesh.
