Abstract/ Executive Summary:

The present study was performed to analyze the genotype-by-environment (G×E) interaction for commonly cultivated 20 commercial maize hybrids over 4 locations and 3 years in Bangladesh. Objectives of this study were to evaluate the magnitude of stability and adaptability of the genotypes in different regions of the country in different environmental status. Multivariate technique was used for grain yield and plant height where two genotypes used as local check. The AMMI model (Additive Main effects and Multiplicative Interaction) was used to assess the interaction and to select better performing ones having higher yield and other potential attributes. Considering the mean, bi and S2di, it was evident that all the genotypes showed different responses of adaptability under different environmental conditions. Analysis of variance showed high significant effects of environments, genotypes and G×E for grain yield and plant height. Among the hybrids Nath Samrat, King-999, Y-367, NK-46, Laxmi-999 and Pacific-60 found highly stable across the environments. Genotypes Nath Samrat, Y-367, NK-46, BHM-5 and Pacific-60 are highly stable as well as high yielder. NK-40 is the highest yielder but responsive to environments. King-999 is the most stable but not good yielder. Burirhat

of Rangpur (Northern part of Bangladesh) was found highly suitable region for hybrid maize cultivation followed by Jessore (Western part).

Program Area: Variety and Species

Commodity: Maize

Objectives:

1.o determine the Genotype Environment Interaction effects on grain yield of maize hybrids for diverse agro-ecological regions in Bangladesh,

2.To identify areas where hybrid maize is well adapted to give economic returns and to select hybrids that are broadly adapted across the maize growing areas in Bangladesh.

Methodology:

The experiments were conducted under Plant Breeding Division of Bangladesh Agricultural Research Institute (BARI) at four different agro ecological zones in the country for three planting seasons (2007-08, 2008-09 and 2009-10). Twenty commercial field corn hybrid varieties including two checks BARI Hybrid Maize3 (BHM3) and BARI Hybrid Maize5 (BHM5) were evaluated in these experiments. The experiments were carried out in a randomized complete block design, with three replications. Each experimental plot was comprised of 5 m long rows. Standard agronomic practices were followed and plant protection measures were taken as required. Two border rows were used to minimize the border effects. Ten randomly selected plants were used for recording observations on plant height. All the plants in two rows were considered for plot yield. The grain yield (t/ha) data was estimated and corrected at 12% moisture.The analysis of variance (ANOVA) was used and the Russell are discussed character-wise as follows; stability GE interaction was estimated by the AMMI model. The stability parameters, regression coefficient (bi) and deviation from regression (S di) were estimated according to Eberhart and Russell. Significance of differences among bi value and unity was tested by t-test, between S di and zero by F-test. All the data were subjected to analysis using statistical analysis package software Cropstat version 7.2 (AMMI, SSA and BANOVA models).

Achievement/Findings:

The AMMI statistical model has been used to diagnose the G×E interaction pattern of grain yield of hybrid maize. Genotypes Nath Samrat, Y-367, NK-46, BHM-5 and Pacific-60 showed broad adaptation with high yield. They were hardly affected by GEI and thus will perform well across a wide range of environments. Burirhat with a relatively stable genotype performance could be regarded as good selection site for identifying broad based and adaptable maize genotypes and other improvement work on maize.
