Latest / Hydroponics Daily / Speed Breeding with Hydroponics
Transcript
- 0:00Hi and welcome back to Hydroponics Daily. It's Friday, it's the weekend.
- 0:04In the UK it's a bank holiday.
- 0:06I'm sat here, we've just cracked open some ciders in the office.
- 0:10It's an 8.2% so it's pretty strong.
- 0:13Today's subject is going to be about speed breeding.
- 0:18So this is hydroponics that's used to increase the speed at which you can breed plants.
- 0:24So you may know that one of my big bugbears when it comes to hydroponics
- 0:27is the term used for indoor commercial
- 0:30hydroponics and it's often called cea or
- 0:34controlled environment agriculture however most
- 0:38of the crops all of the crops grown in indoor hydroponics
- 0:41are horticultural none of them are
- 0:44agricultural agricultural means things like
- 0:47cereals and maize and livestock and things like this
- 0:50and you can't grow wheat hydroponically
- 0:53commercially you can do it experimentally and there have been a number of trials
- 0:58nasa did a lot of work on breeding and growing wheat plants in hydroponics they
- 1:05did it not in florida or texas where you normally expect nasa to be doing their research and
- 1:10No, this particular NASA research was in Utah.
- 1:15Utah, Utah Sates. Do you remember that song from the 1980s?
- 1:191990s, Utah Sates. It's where Salt Lake City is, isn't it?
- 1:22So yeah, in the early 80s, they did lots of research on growing,
- 1:27they bred a type of wheat that could be grown hydroponically, USU Apogee.
- 1:33Apogee is the name of a company that make light sensors as well, isn't it?
- 1:37I think anyway it was dwarf and it could flower a
- 1:40lot faster than normal wheat and get to harvest a
- 1:43lot early so they did a lot of research and then obviously other
- 1:47researchers have been progressing this since to find out
- 1:49the optimum growth conditions for grown wheat
- 1:53they're fairly standard though i mean you know 21 to
- 1:5523 degrees celsius that's normal for most
- 1:58crops in hydroponics a light level of 510
- 2:02to 930 micromoles per meter squared per second that's if
- 2:06you if you know light levels that's pretty standard as
- 2:08well it's not massively high or massively low and 1000
- 2:12to 1200 ppm of
- 2:15co2 which again that's that's standard
- 2:18for the optimum for many plant growing so 20
- 2:2121 to 23 at the day 18 to 20
- 2:24at night and so that they develop new
- 2:27lines of of wheat and they they looked
- 2:30obviously for space travel and things like that and but
- 2:34wheat research has continued and hydroponics has
- 2:37been a key part of that and part of that is speed breeding and
- 2:41this can be applied to other crops so don't if you're not interested in wheat you don't
- 2:44need to turn off but basically when you're when it's
- 2:47an annual plant like wheat or any other type of cereal you
- 2:49normally have one stab doing a cross
- 2:52and growing that cross to see what it results in in your
- 2:57field and your experimental station and then.
- 3:00You can double that up if you have another experimental station in the southern
- 3:04hemisphere so a lot of research organizations have partnerships in new zealand
- 3:08south africa argentina places like this australia and you have you can grow
- 3:13your wheat in the northern hemisphere
- 3:15take the seeds grow them down in the southern hemisphere and vice.
- 3:18And that halves the time it takes to produce inbred lines and go through the
- 3:24number of cycles it requires to produce a whole new variety of any plant.
- 3:29So that's what conventionally happens.
- 3:32So the big breeders will do have a research station down in the southern hemisphere
- 3:36and the smaller ones will only do one.
- 3:39Obviously, with perennial crops, that's not the case, and you just have to grow
- 3:43them for years and years and years, and then cross them when they're mature.
- 3:46So breeding apples is very difficult. It doesn't normally involve inbred lions.
- 3:50But with hydroponics, you can get a number of different crops per year.
- 3:57So you're going from one, potentially, to four to six.
- 4:01So that massively speeds up the amount of crosses you can do.
- 4:06Now, we're not going into the details of breeding and
- 4:09how you deer it in this episode just to the the rationale of
- 4:12using hydroponics now obviously the wheat or any
- 4:15crop you're growing hydroponically will not react in the same
- 4:17way as it will in the field so
- 4:21that's something important to consider now wheat in
- 4:24a hydroponic system will grow completely different until it will outdoors and
- 4:28same for any crop if you grow buddlias hydroponically buddlia
- 4:32is a ornamental plant without any uv light
- 4:35it produces massive of leaves but if you grow
- 4:38outdoors it produces fairly normal fairly small leaves
- 4:41and that's because indoors is completely different so you
- 4:44couldn't breed for a feature about like
- 4:47architecture or even yield really it would
- 4:49really be breeding to breed in a feature that was not going to be influenced
- 4:54by the location so it could be an active ingredient it could be a protein content
- 5:00It could be something that's not going to change between growing it hydroponically
- 5:05and indoors and growing it outdoors.
- 5:08So you'd have to pick a feature, a trait that suited that and wasn't going to
- 5:12be upset by breeding some of the cycles in an indoor grow environment.
- 5:19It's still going to take a long time to grow these plants indoors.
- 5:23And wheat has a very long time. It has to senesce and dry out and things like this.
- 5:27So it's still not fast, but there are a number of research organisations that
- 5:31are now using hydroponics to breed wheat with this speed breeding.
- 5:36Could be a feature more in the future with genetic selection.
- 5:40If you can select a trait from just analysing the genes in the plants and how they're expressed,
- 5:48then you don't actually have to see the trait appear so it
- 5:50could be your your you have a genetic trait for
- 5:54yield or for disease resistance and you're
- 5:56just checking that it's that's appeared in the in
- 5:59the new plants so you might do this with like tomatoes you
- 6:03might have a gene in a wild type plant that
- 6:06you know is related to an antioxidant in
- 6:09the tomato fruit or it might be a
- 6:12color or a texture or ability to withstand
- 6:15transportation without going moldy and things
- 6:18like this and you can rather than do an experiment to find out
- 6:20whether it withstands transportation stuff like
- 6:23that you can just select see the gene is expressed in when you've
- 6:26crossed it into the other variety so with this with
- 6:29this technique you can get a variety of of wheat or
- 6:32any other annual plant in six to seven years
- 6:35which seems like a long time but for a true new variety this isn't a long time
- 6:40that's a short period of time you're talking 15-20 years normally that's why
- 6:45in some perennial or long living plants plants that are dioecious plants that
- 6:51are self incompatible you'll often hear.
- 6:55Rather than saying a variety, they might talk about strains because they're not true breeding.
- 7:00They're not, they'd not be inbred. They're not F1 hybrids and things like this.
- 7:04So that's why you often hear the word strain in certain crops rather than variety.
- 7:09Cultivar is another term that you'll see. That just means cultivated variety.
- 7:13It's a portman chew. Is that the word?
- 7:16They love them in horticulture. Sticking two words together.
- 7:19Polytunnel, plastic tunnel, polythene tunnel, polytunnel, strimmer, string trimmer.
- 7:24There's loads of them i've got a whole list of them once so yeah
- 7:27that's a diversion anyway so that's been hydroponics daily
- 7:30for today speed breeding with hydroponics obviously you
- 7:33can't grow wheat commercially with hydroponics but you can
- 7:36speed breed it and you could
- 7:39then you know have massive inputs and increases in
- 7:42field grown cereals which is what we need if
- 7:45we're going to feed an ever-increasing population so that's
- 7:48been hydroponics daily for today as i say if you're
- 7:51interested in anything you want to get in touch with
- 7:54us please send me an email you'll find us on the eutrema
- 7:57website as eutrema is latin for
- 8:00wasabi you'll also find lots of different biostimulants like tricontinol humic
- 8:04acid seaweed and and liquid gold as we sell in the uk and in america gold leaf
- 8:11until tomorrow i don't know what i'm going to talk about tomorrow but i'm probably
- 8:15going to record it now i'm going to do some batch recordings which will be interesting
- 8:18thank you very much for listening goodbye.
