Abstract/ Executive Summary:

Eight advance lines and two check variety Shatabdi and BARI Gom 26 were evaluated in CVD under irrigated timely seeding (ITS) and irrigated late seeding (ILS) conditions. The genotypes were evaluated for yield and yield components, heading, maturity, Bipolaris leaf blight tolerance, leaf rust resistance, sterility tolerance, white and bold grains etc. Significant difference in yield was observed between optimum and late seeding. Considering overall performance of five genotypes BAW 1135, BAW 1157, BAW 1170, BAW 1177 and BAW 1182 were selected for on-farm evaluation

Keywords: Field Trial, MLT sites, Check variety, Bipolaris leaf blight, Wheat

Location: Dinajpur and Joydebpur

Start Date: 00-00-2013

End Date: 00-00-2015

Program Area: Variety and Species

Commodity: Wheat

Objectives:

To select genotypes from MLT sites (Farmers' Field); to evaluate the performance of the advance lines against the check variety Shatabdi and BARI Gom 26

Methodology:

Eight promising candidate variety were evaluated in this trial against the check varieties Shatabdi and BARI Gom 26. The trial was conducted in optimum and late seeding conditions. The unit plot size was 5m x 4m at each location. The experiment was sown in Dinajpur and Joydebpur during 22 November (ITS) and 25 December (ILS), 2013 in non-replicated plots. Recommended cultural practices were followed to raise the crop. Data were collected, compiled and analyzed in RCB design considering each location as dispersed replication

Achievement/Findings:

The effect of seeding time revealed that all characters under study were significantly influenced by seeding time. The data under both seeding dates were indicated that Shatabdi (4969 kg ha^-1) was the highest yielded in ITS condition followed by BARI Gom 26 (4993 kg ha^-1) and BAW 1182 (4822 kg ha^-1). On the other hand, BAW 1170 (4963 kg ha^-1) was the highest yielded in ILS condition followed by BAW 1157 (4640 kg ha^-1), BAW 1135 (4441 kg ha^-1). There was no significant yield difference due to genotypes. The highest mean yield was recorded in BAW 1170 (4849 kg ha^-1) and the lowest yield was recorded in BAW 1193 (3954 kg ha^-1). The highest yield loss due to late seeding was found in Shatabdi (23%) followed by BARI Gom 26 (20%), BAW 1168 (18%), BAW 1192 (14%) and BAW 1182 (13%), whereas the lowest yield loss was recorded in BAW 1177 (4%) and BAW 1135 (5%) due to late seeding condition. There was no yield loss observed in BAW 1157. BAW 1170 produced higher yield under irrigated late sown condition. So, considering the overall performance BAW 1135, BAW 1157, BAW 1170, BAW 1177 and BAW 1182 could be tentatively selected for on-farm evaluation
