XUEYAN SHA: My name is Xueyan Sha, welcome to the rice breeding stop here.
I have been the medium grain rice breeder
here for the last eight plus years.
Stand next to me is Dr.
Christian de Guzman.
DR. CHRISTIAN DE GUZMAN: Hi, I'm Dr.
Christian de Guzman. I'm the long grain rice breeder at
the University of Arkansas System Division of Agriculture.
We welcome you to the 2021 Arkansas rice
field day here in the breeding stop.
Let me tell you something about myself.
I joined the University of Arkansas last year, September,
taking over the breeding program from Dr.
Karen Moldenhauer.
I previously worked as a Missouri rice breeder.
And I would say that I am extremely fortunate
to lead this breeding program from
the the the distinguished professor
and very successful rice breeder in Dr.
Moldenhauer.
XUEYAN SHA: Today we'll, we will present you our University of Arkansas
System Division of Ag Rice variety lineup.
And also the varieties the latest by the other universities,
and also private companies like RiceTec.
Then we are going and gave you a brief.
introduction of potential lines in
the pipeline to be released in the next year or two.
XUEYAN SHA: First, let me start
With a long grain: Diamond
was released in 2016.
It has been the predominant conventional long grain variety
in the state, last 3 or 4 years in a row, performed really strong.
Got a good a yield potential, got a very stiff straw.
You got fair milling yields also have a very great grain quality,
which is preferred by rice mills.
Then, next to that, we have a newcomer, Jewel.
Released the last year. Yield-wise very comparable compared to the Diamond.
But do have the advantage of the milling yields --
much improved milling yields,
especially the head rice yield.
And also have the Pi-ta for blast resistance,
and the amylose contents over 25 percent,
which is also a plus, preferred by the merchandiser.
XUEYAN SHA: You're probably going to see the two commercial releases from Arkansas,
including ProGold 1 and a ProGold 2.
ProGold 1 also has a Pi-ta for blast resistance.
Both 1 and 2 have comparable yields compared to Diamond.
Then the next one you will see is Dyna-Gro 263.
You have heard about it quite a bit.
It's quite a bit of acreage being been in the state.
This is the first variety developed by Nutrien,
the company from Texas.
You can see it's a semi-dwarf plant type,
Extremely early —— early yield data from the Gulf Coast is
showing up very promising, not only the yields,
but also the milling yields, not only the grain yield.
Also in the pipeline, we have two potential releases possible in the next year or two.
20AR185.
XUEYAN SHA: This is a long grain line,
developed from a cross between Diamond and the leakiest.
The line is about two days earlier in maturity compared to Diamond.
It's also has a very stiff straw.
Milling will be a slight improvement over Diamond. Lodging
is very similar.
It's lacks a Pi-ta for blast resistance,
but overall it's not too susceptible.
We might be looking at an increase in late fall in Puerto
Rico, maybe have a foundation seed grow here next year.
The other line I'd like to mention to you is 21AR211.
This is a semi-dwarf conventional long grain line.
It's showing very good potential in our last year
trial. We're going to look very close.
Hopefully we're going to have a semi-dwarf long grain,
make it available to you in the next year or two.
XUEYAN SHA: Then we're going to switch gears to the Clearfield herbicide technology.
Clearfield, long grain. In the lineup, we have CLL15.
This is variety released two years ago last year, because of the hurricane —
the tropical storm, we did have some issue with the Cercospora,
but we hope this year, the weather is going to be normal.
So the potential will show up. Next to that is
a new Clearfield variety developed here.
It's a CLL16.
You can see it's a very similar plant type compared
to the Diamond yield potential-wise.
Got a Pi-ta for blast resistance.
Milling yields very comparable to Diamond. Maturity maybe
three days later compared to Diamond.
Also has a stiff straw.
Very beautiful kernels.
Next to that is going to be a semi-dwarf
Clearfield long grain recently released from LSU.
It's CLL17. Extremely early, more like CLL111 in the maturity.
The yield data so far, the preliminary yield data from the gulf coast is
showing up very promising.
We have a couple of potential,
We are looking very closely.
DR. CHRISTIAN DE GUZMAN: Yes, we have one potential line.
It's 20AR093.
This is one of the highest yielding Clearfield lines on that segment.
It yields about two hundred seventeen bushels per acre.
That's about about ten bushels per more than
Diamond based on our statewide test last year.
But it's still in an early stage.
We just tested it last year and we are continuing to test
it this year and perhaps another year next year.
But we do have some breeder head rows planted already for that,
just in case we wanted to speed up the process.
Another potential line that we're looking at is 16AR010.
DR. CHRISTIAN DE GUZMAN: This is a conventional long grain line.
It has been tested for several years.
And what we found out is this is the most stable line that we had.
So over the years and over different locations,
we had this line perform really well and stable.
It is a typical long grain and also has a good milling yield.
A little bit better or slightly better than Diamond.
XUEYAN SHA: On the Clearfield potential, we also looking a at the semi-dwarf.
line, which not showing behind me,
but we do have a trial across the mid-south,
not only in Arkansas, the line we call the 20AR121.
This line is actually a true semi-dwarf.
It's got a yield advantage over CLL15 and CLL17.
It's also got a Pi-ta for blast resistance based on the molecular
marker research, it is showing a resistance to Cercospora,
which suddenly became a problem here last year.
We hope this this new thing will provide
the defense against this new disease.
Anyways switching gear to the clear fear medium grain.
We released the CLM04 two years ago.
We are still working tirelessly with Kellog's,
with the Horizon Ag. Hopefully
we can get approval next year before you plant your rice.
CLM04 got a fairly good yield potential.
XUEYAN SHA: A Clearfield, it's comparable to a
non-Clearfield like Jupiter or Titan.
Milling is excellent.
It's not only good but also stable. When you
harvest a little bit late or fairly dry,
low moisture contents more like Jupiter.
Then we looking at a line which is showing promise. It's 18AR238.
This is a medium — Clearfield medium grain three years in trial.
We're showing a yield advantage of about 10 bushels
compared to CLM04. Better than Jupiter.
But we're still working closely with BASF and Horizon Ag.
I tried to moving forward with this line.
It's their final say to release commercially.
Switch gear to another herbicide technology,
we call the ACCase chemistry, which BASF will call
Provisia, RiceTec calls it Max-Ace.
So we have two varieties, behind me one is PVL03.
This new release from LSU, marketed by Horizon Ag.
PVL03 compared to the first generation PVL01 or 02 definitely have
the yield potential improvement. Also have
very stable yields in our trial.
Got a Pi-ta for blast resistance, also have
much improved milling and grain
quality. I guess there's a small acreage in production,
which is looking very promising.
XUEYAN SHA: Next to it is the RiceTec's commercial pure
line, not a hybrid, called Max-Ace,
which is showing excellent yields in last year.
But the Max-Ace, you know, they cannot spray with
Provisia, you have to spray with the Highcard,
the chemical they're marketing through ADAMA.
Then after that we're looking at a line from
Arkansas, which is called a 21AYT53.
We came into the game, breeding Provisia for rice about seven
years later LSU, several years later than RiceTec.
We got an agreement signed in 2019. 25 months
later we have a line in the field looking
really promising. We're going to be waiting for the yield data come in.
Gonna decide, maybe have a small increase purification in Puerto Rico.
Possibly we can have a foundation seed grow here next year.
XUEYAN SHA: Last not least, we're going to talk about a medium grain. In the lineup,
we have the new release called the Lynx, we released last year.
Lynx is being trialed three years in the advance year
trial both in Arkansas and across the mid-south. Over
50 to 60 different trials showing the yield advantage
over both Jupiter and Titan by about 10 bushels per acre.
It's consistent yield.
The quality wise is very good, low chalk,
It's got big plump kernels which preferred by the end user.
We went through two pilot scale trials by Kellogg's.
Those turned out to be positive.
They are eager to go into their factory round.
Hopefully we're going to work out with Riceland, producers,
maybe get enough rice they need for two rail cars.
That's about 2000 hundredweight milled rice
to send to their facility in Memphis.
DR. CHRISTIAN DE GUZMAN: I would like to add Dr.
Sha, we have the aromatic breeding program.
Miss Debbie Wisdom, she's our aromatic rice
breeder and in 2018 we released
ARoma 17. And it's a very good variety, yields about 167 bushels per acre.
And the quality is the typical aromatic. We do have one potential
or candidate line in the aromatic rice segment.
This is the 19AR231. It yields almost identical to ARoma 17.
The difference is that this line has slightly
bigger grains than ARoma 17,
and it cooked a little bit firmer texture compared to that.
So it's, I believe one of the, you know,
differences and maybe it's going to be a different market segment.
XUEYAN SHA: Yeah, come back and talk about medium grain conventional medium grain.
We also have a line which in the closer look
hopefully a potential release in the next year or two.
This is 19AR033.
Last year in the ARPT, highest yielding other than a few RiceTec
hybrids, beat several RiceTec hybrids. Average yield
of 225 bushels per acre compared to 198 for Titan,
so it's about a 10% significant year increase.
We're very excited about this.
Got a really low chalk, it's a true semi-dwarf,
and also got a very big kernel. Before I close,
I'd like to mention our hybrid rice breeding program,
which we put a great efforts in. We
made some progress. Behind me we do have a line
we're looking at, an experimental hybrid.
It's called 11X185.
XUEYAN SHA: This is a two line hybrid. Last year performing
really well at clay soil in Keiser.
We hope this one's going to be standing out this year.
But meanwhile, we are actively working on other new lines.
We'll try to put them out in the next several years.
We would like to say thank you to the Arkansas Rice Research
and Promotion Board for their continued
funding and support; to the University
of Arkansas System Division of Agriculture;
and to the Rice Research Station
staff and crew, that is giving their best in hard work on this breeding program.
XUEYAN SHA: Thank you for your attention.
Hope to see you again next year.
