Abstract: 

THIS STUDY WAS CONDUCTED TO DETERMINE THE COMPETITIVE ABILITY AND FITNESS OF FOUR ARYLOXYPHENOXYPROPIONATE RESISTANT (DR4, NR14, SOR1 AND STR1) COMPARED WITH A SUSCEPTIBLE (S) ACCESSION. UNDER NONCOMPETITIVE GREENHOUSE CONDITIONS, GROWTH OF THE RESISTANT ACCESSIONS WAS SIMILAR TO THAT OF S ACCESSION ON THE BASIS OF SHOOT DRY WEIGHT AND PLANT HEIGHT.SEED PRODUCTION OF R ACCESSIONS WAS NOT DIFFER FROM S ACCESSION. DIFFERENCE BETWEEN RCC VALUES FOR R ACCESSIONS IN MIXTURES WERE NOT SIGNIFICANT TOO.TTHUS, IT APPEARS THAT IN THE ABSENCE OF HERBICIDE THE R ACCESSIONS WOULD REMAIN AT SIMILAR FREQUENCY IN A POPULATION OF R AND S ACCESSIONS.
