Abstract/ Executive Summary:

Varietal adaptability to environmental fluctuations is important for the stabilization of crop production on both region and season. In this context, one thousand six trials with four wheat varieties viz., BARI Gom 25, BARI Gom 26, BARI Gom 27 and BARI Gom 28 were conducted in forty districts of 8 agricultural regions in Bangladesh during 2013-14. Objectives of this study were to evaluate the mean yield performance and yield stability of the newly released varieties in different regions of the country in different environmental status. Yield of 4 varieties significantly varied among the locations. The highest mean yield was obtained from Rangpur region (4275.15 kg ha^-1) followed by Jessore region (4266 kg ha^-1). Yield of these two regions were statistically similar but significantly higher than other regions. In AMMI analysis, AMMI-1 biplot showed that Rangpur and Rajshahi were favorable environments; Sylhet and Comilla were unfavorable environments. Considering varieties, BARI Gom 26 and BARI Gom 25 were more stable and can be recommended for all environmental condition of Bangladesh. On the other hand, BARI Gom 27 was the most sensitive to changing environments. In AMMI-2 biplot, Comilla, Sylhet and Dhaka were the most discriminating environments for all tested varieties, while BARI Gom 26 and BARI Gom 25 were more stable varieties. The most suitable varieties for Rangpur, Rajshahi and Mymensingh was BARI Gom 26; BARI Gom 25 for Sylhet; BARI Gom 27 for Comilla, Jessore and Barishal while BARI Gom 28 was suitable for Dhaka. Among the varieties, BARI Gom 26 and BARI Gom 25 had higher mean grain yield values coupled with small positive IPCA 1 scores and hence these are recommended for all the locations.

Objectives:

The main objective of this study was to evaluate the yield performance and yield stability of the newly released varieties in different regions of the country in different environmental status.

Methodology:

One thousand six trials were conducted with 4 newly released wheat varieties viz., BARI Gom 25 & BARI Gom 26 (released 2010) and BARI Gom 27 & BARI Gom 28 (released 2012) in the farmers’ fields of forty districts out of sixty four under 8 agricultural regions in 2013-14 in collaboration with Department of Agricultural Extension (DAE), Non-government Organizations (NGOs), Cereal Systems Initiative for South Asia (CSISA), On Farm Research Division (OFRD), & Agricultural Research Station (ARS) of BARI. Seven hundred twenty three trials were conducted in collaboration with DAE, eighty through NGOs, forty through CSISA and one hundred fifty one trials by BARI scientists (thirty six through WRC & ARS and one hundred fifteen through OFRD). The pedigree of these varieties are BARI Gom 25 (ZSH 12/HLB 19//2*NL 297), BARI Gom 26 (ICTAL123/3/RAWAL87//VEE/HD2285), BARI Gom 27 (FRANCOLIN # 1) and BARI Gom 28 (CHIL/2*STAR/4/BOW/CROW//BUC/PVN/3/2*VE E#10). Each trial had a single variety with a plot size of 800 m². with no replication. Each of the variety was allotted to a single farmer. Only seed, fertilizers, signboard and printed documents on wheat production technologies were supplied to farmers. All other management practices were done by farmers. A day long training was given to the farmers, related Sub Assistant Agricultural Officer (SAAOs), Scientific Assistance (SA)/Senior Scientific Assistance (SSAs), Upazila Agriculture Officers (UAOs) and Crop Protection Specialist (CPS) of the respective districts about trials, wheat seed production and preservation technologies. Seeds were sown from 10 November to 16 December 2013. Yields were collected from 20 m² (4 samples×5 m²) areas of each trial. A data collection template was supplied to farmers for sending data on yield, sowing & harvesting date, number of irrigations, seed preservation, overall comments, etc. through supervising officials of DAE, NGOs and BARI. In AMMI model, the contribution of each genotype and each environment to the GEI is assessed by the use of the biplot graph display where yield means are plotted against the scores of the IPCA1. The stability parameters and regression coefficient (bi) were estimated according to Eberhart and Russell. All the data were subjected to analysis using two software prgrammes: Cropstat version 7.2 after Zobel et al. and SAS. 9. The AMMI model does not make provision for a quantitative stability measure, such a measure is essential in order to quantify and rank genotypes according to their yield stability.

Achievement/Findings:

The most suitable varieties for Rangpur, Rajshahi and Mymensingh were BARI Gom 26; BARI Gom 25 for Sylhet; BARI Gom 27 for Comilla, Jessore and Barishal while variety BARI Gom 28 was suitable for Dhaka. BARI Gom 26 and BARI Gom 25 were hardly affected by the GE interaction and thus will perform well across a wide range of environments and these can be recommended for all locations. Locations, such as Rangpur and Rajshahi, could be regarded as a good selection sites for wheat cultivation for it’s stable yielding environment.
