Potato seed trials

As potato days around the country are cancelled so Alan Romans is offering seed potatoes which are part of the project he has been promoting for a few years now, trying to raise the next generation of blight resistors in association with the Sarvari Trust. He writes ‘I have combined 3 groups of parents to get 3 different sources of blight resistance over 3/4 years. My technique has greatly improved this season and I have thousands of seeds. I can cope with 100/200 of them at most. Nearly all of the progeny will have some blight resistance with a few having great resistance.

Most will be modern maincrop/ late maincrop ie not daylength dependent for tuberization (like eg Golden Wonder) and could have large yield potential.
To stand a fair chance of useful tubers in one season I would sow the seed in February like tomato seeds in a propagator and plant out as soon as conditions permit. Allow at least 12″ between plants if looking for size. I cram the seedlings as close together as I can to give me more to assess and am happy to get a few minitubers of the more promising to plant on in the following year. I am always impressed by how vigorous the little seedlings are.

My seed, so far, has been very good for one year but then loses much of its viability by year 2 – hence my apparent selfless generosity! It would be great if any members interested would join our very informal group and look out for commercial quality tubers coming from very blight resistant plants, which could be assessed at Bangor University in the future. Good but not essential – I am not getting any younger and the more my crosses get out there the more chance there is that something gets passed on. Regards, Alan Romans’
