I-50 Olive Tree Variety Breeding for High Oil Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current olive tree cultivars lack a variety that combines specific desirable traits such as high oil yield, early bearing, and ease of agronomic management, with existing varieties either having lower oil content or less manageable characteristics.
Innovation Solution
A new olive tree variety, 'I-50', is developed through controlled cross-pollination between 'Arbosana' and 'Koroneiki' varieties, exhibiting distinct characteristics like spreading growth habit, low fruit weight, black fruit color, and high oil yield, which are stable through asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing olive tree varieties are used, then certain characteristics are maintained, but high oil yield and early bearing cannot be achieved simultaneously
Solution Approach 1:
The patent combines the high oil yield characteristic from Koroneiki (28-30% oil content) with the early bearing capability from Arbosana through controlled cross-pollination, creating a new variety that exhibits both traits simultaneously. The hybrid offspring inherits favorable genes from both parents to achieve high productivity without delaying bearing time.
2Ease of operation
If existing olive tree varieties are used, then certain agronomic characteristics are maintained, but ease of management cannot be achieved
Solution Approach 1:
The new variety exhibits specific local qualities including spreading growth habit that facilitates canopy management, moderate tree size that simplifies harvesting operations, and high oil yield capability. These localized traits are optimized for ease of agronomic management while maintaining high productivity.
3Productivity
If related varieties I-15 and I-30 are used, then certain characteristics are achieved, but the specific combination of early bearing and high oil yield is not obtained
Solution Approach 1:
The patent creates an asymmetric breeding approach by using Arbosana as the seed parent and Koroneiki as the pollen parent, rather than using symmetric or conventional parent combinations. This asymmetric cross-pollination strategy produces offspring with distinct characteristics including earlier bearing than I-15 and at least 3 percentage points higher oil yield than I-30.

AI summary
A new and distinct variety of olive tree, herein referred to by its cultivar name, ‘I-50’, is provided which forms a spreading growth habit. Fruit with a low weight and obtuse shape is produced. The fruit exhibit black coloration and the fruit nipple is either absent or weakly present. The stone of the fruit of the new variety is of very low to low weight, very elongated and possess a weakly rugose surface.
