Summary
Researchers developed new purple-grained triticale using marker-assisted breeding. These novel wheat-rye amphiploids exhibit high anthocyanin content, offering potential health benefits and improved crop characteristics.
Area of Science:
- Plant breeding and genetics
- Nutritional biochemistry
- Agricultural science
Background:
- Purple-colored cereal grains are rich in anthocyanins, beneficial polyphenols with high antioxidant activity.
- Triticale (wheat-rye amphiploid) currently lacks varieties with purple grain color.
- Anthocyanins contribute to human health benefits due to their antioxidant properties.
Purpose of the Study:
- To develop new purple-grained triticale forms using marker-assisted breeding.
- To evaluate the anthocyanin content in the developed purple-grained triticale.
- To compare the productivity indicators of these novel triticale forms.
Main Methods:
- Marker-assisted breeding was employed to cross triticale (Sadko) with purple emmer wheat (27-3/17).
- Molecular DNA markers identified hybrids carrying complementary dominant genes (Pp3 and Pp-B1) for purple grain color.
- Anthocyanin content and agronomic traits (yield, grain weight, spike characteristics) were analyzed.
Main Results:
- Purple-colored F3 hybrids homozygous for Pp3 and Pp-B1 genes were successfully obtained.
- Total anthocyanin content in purple-grained triticale flour ranged from 36 to 529.3 μg/g.
- Hybrid plants exhibited improved spike length and number of spikelets compared to emmer wheat, with grain weight comparable to the maternal triticale form.
Conclusions:
- Novel purple-grained triticale forms with significant anthocyanin content have been developed.
- These new triticale varieties possess desirable agronomic traits, including yield potential exceeding emmer wheat.
- The developed breeding material represents a valuable resource for enhancing cereal crop nutritional value and diversity.

02:50Transgenic Plants
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...

01:59Plant Breeding and Biotechnology
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

02:16Light Acquisition
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
