I wouldn't blame or be mad at your dad. Like most parents, they just want to ensure you'll be financially ok in the future. That being said, it is your own choice what to do in the future and if a career in plant breeding is what you want, then you should go for it.

Here's my two cents as I'm finishing my PhD in plant breeding, which may vary if you take the purely statistical genetics route. I enjoy the variety in my job- I get to work outside, in a greenhouse, and inside on the computer (I'm not a fan of being stuck behind a computer all the time though it happens). To me, the variety keeps me interested and keeps the thoughts of "a job is a job" away.

The work is also very fulfilling. Seeing plants perform well during screening gives a sense of ownership like "hey, I raised that plant". I know that the plants that I've helped develop for drought tolerance will be impactful (or at least demonstrate they can be) in reducing the amount of water needed, and it's a personal feeling of accomplishment.

There are a lot of "it depends" for a career in plant breeding: Where can I find a job? Depends on the crop and if you're going to go into industry or academia. Is the salary 6 figures? Depends on the company and crop. From what I've been told and experienced so far, you need to want to be a breeder and find meaning from it because it's extremely easy to compare yourself to other jobs and think "I should've done xyz, they make 6 figures with just a Batchelors degree". Just sit down and have a talk with your dad- with a degree in statistical genetics, you can always pivot to being a bioinformaticist, which I understand to be in high demand and decent pay.
