New genetic research from the University of Florida could lead to the development of tastier, more disease-resistant blackberry varieties. These new cultivars aim to support growers, particularly in Florida, where the citrus industry has declined, while meeting the rising global demand for blackberries.
Consumer interest in blackberries has surged over the past two decades, with U.S. production reaching 37 million pounds (circa 16,8 milioni di kg) of processed fruit and nearly 3 million pounds (circa 1,36 milioni di kg) of fresh berries annually. In Florida alone, 277 farms produced blackberries across 702 acres (circa 284 ettari) in 2022.
Lo studio genetico e la varietà BL1
The study, led by UF/IFAS professor Zhanao Deng, focuses on decoding the genetic structure of blackberries through advanced genome sequencing. Using an experimental blackberry known as BL1, the research team reconstructed its complete genome sequence to better understand key traits.
BL1 is a tetraploid fruit, meaning it has four copies of each chromosome, which makes breeding more complex compared to diploid fruits like raspberries. By releasing the tetraploid genome, researchers provide a valuable tool for developing new cultivars with improved fruit quality and stronger disease resistance.
Caratteristiche genetiche e vantaggi futuri
The genome also sheds light on important characteristics such as thornlessness and anthocyanin production, the pigment responsible for the berries’ deep color and health benefits. This knowledge could help enhance both the nutritional value and market appeal of future varieties.
For Florida, the southeastern U.S., and similar climates, these genetic insights promise to accelerate the breeding of blackberry cultivars adapted to local conditions, leading to higher yields, better quality, and improved profitability for growers worldwide.
