Gönen Plain is among foremost rice growing areas of Turkey. Weeds have been one of the prominent problems in rice cultivation. Echinochloa spp. have become main weed in Gönen as it has been happening in many other rice production areas due to their high populations in rice fields, hybridization capacities, adaptive and competitive abilities, their herbicide resistant biotypes and morphological similarities to rice. Their effects on yield changes among species, even among lower taxons. Reactive measures have not solved the problem so far. There is a need for an approach based on biology and ecology of Echinochloa spp. For this aim, paddy fields have been visited randomly in Gönen plain in rice growing season of 2021 to identify species and find out their morphological characters in the context of maturation time. Several Echinochloa spp. identification keys appropriate with the region were selected from the local and global literature. Using these keys, 27 Echinochloa crus-galli, three Echinochloa oryzoides and two Echinochloa oryzicola, which are known to exist in the region, and five Echinochloa colona, a species whose existence was previously unknown in the rice fields of the region. In addition, few subspecies of Echinochloa cruss galli were identified, namely, 11 E. crus-galli var. crus-galli, one E. crus-galli var. austrojaponensis and two E. crus-galli var. mitis.
