Survey of <i>Echinochloa</i> weed species in rice fields using a chloroplast DNA marker and spikelet characteristics identifies accessions with possible paternal inheritance and heteroplasmy.

ABSTRACT: Hexaploid Echinochloa. crus-galli var. crus-galli and tetraploid E. crus-galli var. oryzicola are major weeds in rice fields. Supplementing molecular marker data with morphological and morphometric characterization is considered a reliable method for species identification. In the present study, Echinochloa weed accessions were collected from rice fields in Tamil Nadu, India [as plants (12) or seeds (10)]. Species level identification was carried out using the distinguishing chloroplastic DNA marker, trnT-L. Eight accessions were identified as E. crus-galli consistently across T₀ and T₁ generations and twelve others over a single generation (T₀ or T₁). Spikelet length is an important feature used t
