Compact Alstroemeria Cultivar With Long Bloom and Cold Hardiness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Alstroemeria varieties lack compact growth, robust flowering, and cold hardiness, with limited flower color diversity and longevity.
Innovation Solution
Development of the Alstroemeria hybrida 'TURCAL211' cultivar, characterized by compact growth, sturdy stems, bright cherry red flowers with a yellow center, and a long flowering period from June to October, and cold hardiness down to −12° C, achieved through controlled breeding and tissue culture propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If Alstroemeria varieties are bred for compact growth, then plant height is reduced, but flowering period and cold hardiness are limited
Solution Approach 1:
The breeding program systematically varied genetic parameters through controlled crosses between different Alstroemeria lines, selecting for combinations that simultaneously achieved compact stature (20-30 cm height), extended flowering duration (June to October), and cold hardiness (survival at -12°C). This multi-parameter optimization resolved the contradiction between reduced plant size and extended flowering period.
2Length of stationary object
If Alstroemeria varieties are bred for compact growth, then plant height is reduced, but cold hardiness is limited
Solution Approach 1:
The breeding program systematically varied genetic parameters through controlled crosses between different Alstroemeria lines, selecting for combinations that simultaneously achieved compact stature (20-30 cm height) and cold hardiness (survival at -12°C). This multi-parameter optimization resolved the contradiction between reduced plant size and improved cold hardiness.
3Quantity of substance
If Alstroemeria varieties are bred for robust flowering, then flower production is increased, but stem strength is reduced
Solution Approach 1:
The breeding program systematically varied genetic parameters through controlled crosses, selecting for optimal balances between flower production (multiple blooms per stem, prolonged flowering) and stem strength (sturdy, non-floppy stems). This multi-parameter optimization resolved the contradiction between increased flower production and maintained stem strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cultivar 'TURCAL211' exhibits stable, compact growth, robust flowering, and enhanced cold tolerance, distinguishing it from other varieties with unique flower color and extended flowering duration, suitable for both pot and garden cultivation.
Implementation Method 1
The first asexual reproduction was performed by tissue culture in 2016, at the same nursery in Mazé-Milon, France.

AI summary
A new and distinct cultivar of Alstroemeria plant named ‘Turcal211’ is disclosed, characterized by uniquely low growing/compact plants with excellent pot and garden performance. Plants are very floriferous with a long flowering period from June to October. Flowers are bright cherry red with a yellow center with stripes. Hardiness to −12° C. has been observed. Foliage is healthy and green, also during the flowering period. The new variety is an Alstroemeria, typically produced as an outdoor ornamental plant.
