Is there a genetic component to prone-ness to blossom end rot?
The reason I am asking is because some tomatoes seem to get it, and others seem highly resistant.
I know that it has to do with calcium transport, but simplistic explanations like watering or lack of soil calcium don't seem to hold water. It seems to be a variety of stresses, and this year it might have been widely oscillating temperatures.

which varieties of yours got it this year, Atash?
the only one of mine out of 25 varieties that got a mild case, is the greensleeves aka green sausage. its also the only long-type I grew. all others I grew are beefsteak, and round types, and cherry types.
cherry types never get BER. at least in my experience.

I got BER on greensleeves too.
Another one that got it fairly bad--lost several tomatoes to it--was Forest Fire.
One that got a minor case--lost 1 fruit--was Silvery Fir Tree.
I've never seen BER on a cherry type either. Cherry types seem to be immune from a number of tomato mishaps.
It seems to me, that if there is a genetic component--maybe something that is a side-effect of something else--then breed it out.

Greensleeves were getting a bit of BER at my friends house near Monroe, but I think the addition of Dolomite lime corrected that. They were in dripped watering hanging baskets, therefore the excess drainage probably affected the available lime, etc. Sometimes roma type tomatoes are prone to this problem.
