Raspberry cane advice

I don’t know what breed mine are, they were 3 single plants bought in Aldi or Lidl, and I just cut them back each year and dig up the runners and replant the good ones into my raspberry hedge. Mine fruits in June mainly continues into July. Now there are no fruit but lots of new leaf growth. I must consider planting some late varieties. I did hear from someone previously about those yellow or gold raspberries and was told the taste and berry structure was very poor so I didn’t pursue.
