Thank you for the info, you are luck to have more than one

I do hope that with times, the seeds will improve.
My father has a big white pine, I think it is a glauca, on its roots, in a one cubic meter plastic pot. It has been producing a lot of big seeds in the last few years. But they are all dud. I am planning to take it over and plant it next to my black pine this winter. I have been digging the hole already.
Hi shibui,
Thank you for the advice, I have been thinking about it too. I am going to cut two or three off this weekend.
Best regards.
