The main goal of wheat breeding

The main goal

- new high yielding winter and spring wheat varieties, characterized with good lodging and diseases resistance, grain quality suitable for food or feed.

The main tasks of the wheat breeding

• Collect and investigate local material (landraces) from different districts of Latvia

• Test and evaluate suitability of foreign varieties to Latvian agroclimatical conditions

• Initiate breeding work (selection of elite plants from local forms and foreign varieties)

• Apply hybridization methods

Ancestors of the first Latvian wheat

varieties Winter wheat

‘Söl’ ( Swalöf Sweden), characterised by good resistance to lodging, but week winter hardiness.

‘Sandomiras’ (Poland) had a low lodging resistance, but good winter hardiness and baking quality.

‘Kuverta’ (Eastern Prussia) had a lodging resistance, relatively good winter hardiness, but poor baking quality.

Local winter wheat material with white awned (graecum Körn), white awnless (albidum Al., lutescens Al.) and red awned forms

Spring wheat

‘Janetzki’ (Valtdorf Germany) or local variety from Hungary had a good lodging resistance.

‘Rubin’( Swalöf Sweden) had a rezistance to Ustilago nuda (Jens).

‘Diamant’ (Swalöf Sweden) had a good lodging resistance and rezistance to Ustilago nuda (Jens).

‘Kitcener’ (Canada), ‘Extra Kolben ’ (Sweden)

Wheat breeding methods

1945-1960

• Selection of branched wheat

• Wheat transformation (spring to

winter type and winter to spring

type)

• Vegetative hybridization- grafting

wheat germs on the endosperm of

other plant species (Triticum

timopheevii (Zhuk) Zhuk, Triticum

dicoccum (Shrank) Schucbl.),

branched wheat, rye

• Treating wheat grain with

radiation

Branched wheat

Branched wheat

Wheat breeding methods

1970-1990

• Winter hardiness – cold resistance

(field – laboratory test)

• Resistance to fungal disease (on the

artificial background Tilletia tritici

(Bjerk), Puccinia tritici

(Eriks&Henn) (race 77, 76), snow

mould Fussarium nivale (Fr.) (Ces)

• Resistance to Oscinella frit (Linn)

• Lodging resistance - using

laboratory methods

• Grain quality- suitable for feed

(Lysin content)

The aim of current wheat breeding- employing classic and biotechnology methods, to create and

introduce into production winter and spring wheat varieties

adapted for conventional and organic management, with grain

quality corresponding to food industry requirements and to

evaluate and maintain Latvian wheat genetic resources.

Wheat breeding methods

• Enlarging of wheat genetic resources in breeding programs (agreements with CIMMYT, ICARDA and Oregon State University USA, newiest varieties from abroad)

• Introduction of new grain quality testing methods for different end use products

• From 2000 the new methods of biotechnology (doubled haploids, DH) were employed in wheat breeding programs with the aim to speed up the breeding process.

Results of wheat breeding

From 1990 to 2010 at the State Stende CBI the

4325 winter wheat crossing combinations were

done and 125 456 fertile seeds were obtained.

The average of fertility was 35.4%.

The 1765 spring wheat crossing combinations

were done and 84 200 seeds were obtained. The

average of fertility was 32.8%.

Results of wheat breeding

• During 90 years 16 winter and 11 spring

wheat varieties of bread wheat (Tr.

aestivum L.) have been originated at

Priekuļi and Stende, and introduced into

the market.
