strain consistency over decades

[Guest]

There are several varieties that ive grown for nearly a decade now, and a couple of them have changed slightly over that time. Not in potency or affect, but in plant structure and behavior.

The best example is that of sensi star. The plants' vigor and growth rate has deminished slightly over the period and there seems to be a bit more variation in the line. On the positive, its mould resistance has actually improved. The first year i grew it, it was bad succesptable, now it seems somewhat resistant.

Still good smoke, hits hard, but.

Wonder why?

hey SB hows it going

i have enountered some strains that do that, lose some quality/qualities over time and some that actaully get better over time as they get run again and again. some of the latter is due to leaning the plants sweet spot, but i have had an afghani in particular that was perhaps the most potent weed ive ever smoked but it sucked the first run

I have noticed that some plants change growth pattern if i take clones after i flower them and even though it goes baack to a normal growth pattern in veg when i take the same plant and take a cut, root it and go to flower it, it gets the changed growth pattern, particularly in the case of one mom ive had for close to 7 years. I have several sisters and they were done proper, veged, cut taken, rooted and flowered, and all they are all good so i think there are som variables involved as well

its a plant designed to die and regrow form seed every year so plants running for years are really just responding to a mock grow season that doesnt end and its a luxury we have that many of the best strains are ok with it

i woudl think the advent of femanized auto flowers may change that but thats a bit off topic

You may be right ureap . the SS imentioned isn't less potent or have lower yields, its just that the first 2 weeks or so she seems slow. As an outdoor grower, ive decided the past few years to veg her for 3 weeks before planting so that it will get past the slow spot. Ive dismissed the possibility that its something in my behavior because ive been using the same soil and lighting as with the first grow of it.

I have a question ureap. The mother you'v e kept for 7 years, is that the same plant for all of that time or is it a line cutting year after year?

Is it the case that breeders such as paradise keep the actual plant for years or a cutting carrying the genetics? I would think it would be very difficult to keep the same (annual)plant alive for years. ??

good question, i'd imagine breeders would move on to a new cutting of the mother plant(s) quite often, i reckon as soon as that mum shows for example even the slightest sign of LSF, bug damage etc they'd move on to a brand new, un-damaged cutting,

look what's happened to the Uk Cheese/Skunk #1 over the years, it's lost alot of vigor through continual cuttings of a cutting of a cutting etc, it now has very poor vigor (or at least the 1 i had was), i wonder if this is possibly the reason why it's so prone to spider mites as well? - over time the plant loses it's natural ability/resistance to fight off pests/diseases?

Alot of the Dutch seed companies over the years have lost their prized breeder males or females (by mistake, bust, stolen etc..), then have to resort to different parents to continue the line.

For Example: I spoke with Sagarmatha thru PM back over a year ago about the current Bubbleberry (originaly released in 1996) and was told the seeds were now f2's .

In this particular case, early in her life, wihtin the first year or two i had to take a clone off of a flowering plant the keep her ruinning

i rooted the cutting and put her into veg, and she appeared to go back to normal growth stage, but ever since, anything i take from her and flower stretches and has an effect on how and where the internodes line up

the seed sisters ive popped and grown, grow as she did before i flowered and took a cut

the only differential is her flowering growth pattern, but wasnt a benefit

in all other regards she seem sfine, and its still a great way to rescue genetics (cuttings after fowering starts) but it may not be the best way to perserve a particular plant for long term propagation

as far as keeping a plant for all those years, for many strains its really no big deal to keep the same plant alive and healthy for a deade or two

the biggest threat of keeping a plant long term, besides the plant having a built in genetic time clock, is root disfunction from it being in the same container for so long

if you keep the plants soil renewed, root ball maintainted and well tended it should have many years of performane to her

it's not natural to keep a plant that is naturally an annual..that wants to seed itself to restart it's life...you are keeping it alive..which in turn stresses the plant..which in turn causes genetic slide or genetic differences/deformities..I have never successfully kept a plant..unless I made f2's...that;s the only way to truly keep the genetic make up of your plants..and even then you get lots of variation...due to inbreeding...this is why all the breeders have and will continue to lose those plants they use.it's inevitable..

As Hazeseeker says above, the UK Cheese is a great example.. unless it was always as slow growing as the one I have now is! Compared to the vigour of fresh F1s its growing alongside, it vegs sloooow.
