Abstract
Abstract Improved plants of Brassica oleracea and seeds capable of forming the same are provided. Such plants are fully male and female fertile and possess the usual complement of 18 chromosomes. However, unlike previously available cole crops, these plants exhibit cytoplasmic triazine tolerance when atrazine is applied as a foliar spray at a rate of 1.5 kilograms per hectare. For the first time a triazine herbicide can effectively be used to destroy unwanted broadleaf weeds which have a propensity to grow in the same planting area with the cole crop. Accordingly, an improved process for producing a cole crop is provided through the application of triazine to the planting area.

Claims Analysis
Total Claims: 39
Claim 1
Independent Claim
88 words
An improved process for producing a cole crop in the substantial absence of unwanted broadleaf weeds while growing in a planting area which normally would have the propensity to form such broadleaf weeds comprising: (a) growing Brassica oleracea plants in said planting area which are fully male and female fertile, possess 18 chromosomes, and exhibit cytoplasmic triazine tolerance, (b) contacting said planting area with triazine in an amount sufficient to substantially destroy broadleaf weeds while maintaining said Brassica oleracea plants substantially intact, and (c) harvesting the cole crop.
Claim 2
Dependent Claim
