G × E interaction for growth,yield and quality characters of strawberry (Fragaria ananassa Duch.) under Bangladesh conditions

A multi location trial with five promising strawberry genotypes viz.,sweet charlie,festival,camarosa,fa 008 and bari strawberry-1 was conducted under different sub tropical climatic conditions of bangladesh to study their gxe interaction. location were gazipur,rajshahi and chittagong during the period from august 2009 to may 2011. combined analysis of variance indicated significant variation among the genotypes as well as location for almost all the characters studied. genotype x environment studies indicated different response of genotypes over locations for most of the characters suggesting location wise environmental variation. stability parameter revealed that a particular genotype did not perform consistently for all the characters. the genotype festival considered as stable for most of the characters except days to flowering and ascorbic acid content of fruits,and considered as stable over different locations. for this reason,the genotype 'festival' could be well thought-out and less receptive to the environmental conditions and might be recommended for all environments. on the other hand,environmental indices indicated that the environment of rajshahi was found to be most favourable for strawberry cultivation followed by that of gazipur and chittagong.
