Perennial Rye Breeding Services

INQUIRY

Rye is a significant species within the rye genus of the grass family, encompassing cultivated varieties (Secale cereale) and their wild relatives (such as Secale strictum). Compared to annual rye, perennial rye exhibits sustained multi-year growth, expanding populations through tillering and rhizomes, and adapting to diverse climatic and soil conditions. With growing demands for sustainable agriculture and low-carbon cultivation, perennial rye is emerging as a key direction for food production, pasture improvement, and ecological conservation.

Lifeasible is a specialized plant biotechnology company dedicated to providing comprehensive solutions for perennial crop breeding. Leveraging our advanced breeding technology platform and robust team of technical experts, we play a pivotal role in advancing perennial rye breeding.

Advantages of Perennial Rye Breeding

  • Reduced production costs. Perennial rye cultivation lowers tillage frequency, thereby enhancing long-term soil productivity while reducing farmers' labor intensity and expenses.
  • Sustainable agriculture and soil conservation. Perennial rye's stable root system and extended ground cover duration help mitigate soil erosion and boost soil carbon sequestration.
  • Climate adaptation and stress tolerance. Perennial rye exhibits enhanced winter hardiness, drought tolerance, and tolerance to poor soils. Cultivated on marginal lands and in ecologically fragile areas, it enhances land utilization efficiency.

Our Service for Perennial Rye Breeding

Hybrid breeding and backcrossing

By crossing cultivated rye with perennial wild species, followed by backcrossing, selection, and selfing or polyploidy treatment of F1/F2 generations, we balance yield and perenniality to develop perennial rye materials suitable for grain or forage.

Ploidy manipulation and cell engineering

We induce stable inbred lines or polyploid materials through artificial ploidy manipulation to enhance adaptability and grain setting rates. Auto-polyploidy or synthetic polyploidy trials in perennial rye address fertility and genetic stabilization challenges.

Genomic selection (GS) and marker-assisted selection (MAS)

Applying GS to complex quantitative traits (e.g., perenniality, yield, adaptability) significantly accelerates breeding cycles. Combining QTL/marker data enables precise selection for key resistance or adaptability genes. Our prior research demonstrates outstanding results when integrating GS with high-throughput genotyping and phenotyping platforms.

Population genomic analysis

Using diverse populations for association studies, we identify loci linked to perenniality, winter bud differentiation, and root development, providing targets for molecular breeding.

Additionally, we employ high-throughput phenotyping with multi-environment trials, tissue culture, and rapid breeding techniques to accelerate the screening of superior materials in perennial ryegrass breeding, thereby shortening the breeding cycle.

Our Service Process

  • Breeding program design and material screening. We develop hybridization strategies, parental selection, and initial screening approaches based on client objectives. 
  • Parental sourcing and hybridization operations. We provide cultivation services for rye and related perennial materials, parental characterization, and artificial hybridization services. 
  • Ploidy manipulation and tissue culture. We implement automated polyploidy synthesis, embryo rescue, and asexual propagation to enhance breeding success rates.
  • Molecular genotyping and genomic selection support. We offer a comprehensive workflow, spanning from DNA extraction to GBS/chip genotyping, genotype data analysis, and GS model establishment.
  • High-throughput phenotyping.
  • Varietal trait analysis.
