COMPETITION BETWEEN EIGHT GENOTYPES OF CHAMOMILE [CHAMOMILLA RECUTITA (L.) RAUSCHERT]

Among medicinal plants, chamomile is a species mostly cultivated in Paraná state, where the genetic materials importation took place in an occasional way for years.
In this investigation, the behaviour of eight chamomile genotypes was observed: Argentina, BK-2, Bona, DS, Egito, Goral, Lutea and Mandirituba.
The study was carried out in 1996, in the city of Pinhais, Paraná, Brazil, (25° 26′ S and 49° 16′ W, 947 meter above sea); Cfb by Koeppen climate, average temperature of 24°C maximum and 11°C minimum, annual rainfall average 1500 mm.
The height, weight and health of the plants in three different ages was evaluated along with the production levels at three different times.
The results showed that DS was the best genotype in terms of production and rusticity; Egito, Mandirituba and Argentina genotypes presented precocious growth, the greatest height and consequently the highest lodging tendency; BK-2, Bona, Lutea and Goral showed to be susceptible to Erwinia carotovora, despite the good production of BK-2 and Bona.
