It is not too difficult to breed a rose that is resistant to disease.
What’s difficult is breeding a rose that has the exquisite mix of fragrance and form that defines an English Rose and also exhibits exemplary disease-resistance. Health and vigor have always been key components in breeding for David Austin Roses in Albrighton, England. Over the past decade, Austin’s team has raised the bar for disease resistance even higher.
While it is impossible not to spray roses grown in a commercial monoculture without getting at least some disease, since the 1990s the David Austin trial fields have been sprayed for pests and diseases only at very bare minimum levels, if at all. With this practice, only the very strongest and healthiest varieties make it through the selection process.
The David Austin Breeding Process
The David Austin Roses breeding program focuses on romantic color, fragrance, repeat-bloom from late spring/early summer to frost, attractive foliage and garden performance, including health and disease resistance.
"Once a breeding candidate satisfies these initial strict criteria, it must then pass the hurdle where its overall charm and beauty determine whether it has 'the magic' required to become a David Austin English Rose," said Michael Marriott the Austin technical director.
The breeding program is directed by Austin principals David C.H. Austin and his son David J.C. Austin, and Carl Bennett, Austin’s longtime Rose Breeding Manager. In identifying final candidates for English Rose trialing, they are scrupulous in selecting only those that exhibit certain “must have” attributes, in combination:

Thousands of Crossings, Years of Patience
In traditional selective breeding good parentage is all. But a program designed to breed varieties that meet such criteria must by necessity be massive in scale involving many thousands of crosses of many parents. The David Austin breeding program makes about 50,000 precisely monitored cross-pollinations each season, growing about 150,000 seedlings per year from the resulting seeds.
Only a small proportion of these will display all of the characteristics the Austin breeders look for and move forward to further trialing. In the end, only two, three or four are chosen each year and it is a combination of overall charm and performance that wins out. A David Austin rose must be as tough in the garden as it is beautiful.
The process is a long one. It typically takes 8 to 10 years for a new rose to make the final cut and become an official David Austin English Rose.
