I love using some of Will Radler's roses in my breeding program. He has done amazing work to help clean up roses available on the market. One of my favorites of his to use in crosses is RADsweet, AKA 'Alaska'. In my climate it has very good black spot resistance, but unlike the original 'Knock Out'® rose, it also has good powdery mildew resistance. Two other things that I have noticed about RADsweet is that it can produce yellow seedlings and it does a better job of accepting the blotch than most of the other Radler roses. The one below was used extensively in my breeding program this year. Please notice the beautiful and clean foliage. If you have the opportunity to find it and you are a rose breeder, consider using 'Alaska' in your breeding program.
