Tiren (F1) is supposed to be an improvement on San Marzano. It is notable in my garden for having severe blossom-end-rot, while no other plants have any issues with it at all.
Anyone else have experience growing the variety?

what kind of improvement is it supposed to be? i always got a fair amount of BER on 'regular' san marzanos.

I'm not sure, actually. I remember reading that phrasing as market-speak, rather than anything specifically meaningful. It is definitely "improved" from the vendor perspective because it is a F1, so you'd have to return to them for seed each year. One seller (http://guide.alibaba.com/shop/new-early-classic-san-marzano-shape-tiren-f1-tomato-seeds-fruit-vegetables-seeds-50-seeds_6232221.html) describes it as "Earlier and higher yielding" than San Marzano, which would be useful, as the San Marzanos I've grown have been somewhat late/slow in production.
The few times I grew the regular SM I didn't note any BER, but I'm now on new property with totally different soil. The previous yard was heavy clay, while this one is mostly sand. Tiren might have done just fine in the clay (as the SM did).

Grew Tiren for the first time this year and had some BER (<10% had BER). I grew 4 other varieties and none of them had BER. The plants are very prolific although most of the shoulders don't ripen on the vine.
