Floribunda Rose Cultivar ALTladyfirst Continuous Blooming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current garden rose varieties lack continuous blooming and disease resistance, with limited environmental adaptability and fragrance, making them less suitable for commercial ornamental applications.
Innovation Solution
The development of Rosa 'ALTladyfirst' cultivar, characterized by double pink flowers with a white basal blotch, strong tea rose scent, light green glossy foliage resistant to black spot and powdery mildew, early blooming, compact growth, and continuous flowering, which can be grown on its own roots without grafting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current garden rose varieties are used, then they are easy to grow, but they lack continuous blooming and disease resistance
Solution Approach 1:
The patent applies parameter changes by selecting and breeding rose plants with specific genetic parameters that confer both disease resistance and continuous blooming capability. The inventor evaluated multiple plants and selected those with desirable traits, then propagated them through cuttings to maintain stable inheritance of these parameters, resolving the contradiction between reliability and productivity.
Solution Approach 2:
The new rose variety exhibits multi-functionality by simultaneously providing disease resistance, continuous blooming, and ornamental value. The plant serves multiple purposes: it protects against black spot and powdery mildew while maintaining continuous flower production, making it a universal solution that addresses multiple gardening requirements simultaneously.
2Adaptability or versatility
If rose varieties with strong fragrance are developed, then aesthetic appeal is enhanced, but breeding complexity increases
Solution Approach 1:
The inventor engaged in preliminary action by conducting a systematic breeding program starting in 2012, deliberately selecting parent plants and monitoring offspring to develop the desired fragrance trait. This preliminary, organized approach to breeding simplified the overall process by planning and directing the selection process rather than relying on random variation.
Solution Approach 2:
The breeding program utilized self-service principles by allowing the plant's natural genetic traits to guide the breeding process. The inventor observed and selected plants that naturally exhibited strong fragrance and continuous blooming, then propagated them through cuttings, enabling the plant's own characteristics to serve the breeding objective without complex external intervention.
3Volume of moving object
If compact plant growth is achieved, then space efficiency is improved, but growth rate may be reduced
Solution Approach 1:
The patent applies parameter changes by selecting plants with specific genetic parameters that produce compact growth habits. The inventor evaluated multiple plants and selected those with desirable compact traits, then propagated them through cuttings to maintain stable inheritance of these parameters, achieving compact size without significant growth rate reduction.

AI summary
A new and distinct cultivar of Rosa plant named ‘ALTladyfirst’ is disclosed, characterized by early blooming double flowers composed of pink petals with a white base. Flowers have a strong tea rose fragrance. Plants are vigorous and can be grown on their own roots. Plants are compact, flower continuously and exhibit good resistance to blackspot diseases. The new variety is a Rosa, normally produced as an outdoor garden or container plant.
