Research Reveals New Method for Developing Raspberry Varieties

E-mail Print

Study supports new breeding strategy for machine-harvested raspberries

Researchers examined an alternative strategy for developing machine-harvested red raspberries. They bulk machine-harvested full-sib family plots for among-family selection and used yield component data on individuals within the plots for within-family selection. The approach showed higher genetic gain per generation using estimated individual machine-harvest breeding values than using hand-harvested breeding values. Implications for breeding machine-harvest red raspberries are discussed in the report.

How Exposure to Irregular Light Affects Plant Circadian Rhythms

E-mail Print

Study outcomes could translate to energy savings for greenhouse operations

A study of chrysanthemum investigated plants’ circadian responses to interruptions in light cycles. Plants were exposed to irregular supplemental light breaks during the night; results showed a correlation between circadian-regulated processes and plant growth. Leaves and stems grew faster in plants grown in short days with irregular light breaks during the night compared with plants grown in a climate with a consecutive long light period. The findings could contribute to energy savings in production greenhouses.

Pest Preferences for Cranberry Cultivars Determined

Six compounds found in cranberry leaves may naturally reduce insect feeding, growth

To determine whether insect herbivores have a feeding preference for certain cultivars of cranberry, researchers investigated the phenolic profiles in the foliage of two cranberry cultivars, then isolated and identified compounds that differed between the two cultivars. Gypsy moth larvae demonstrated a significant feeding preference for ‘Howes’ over ‘Early Black’ cranberry. Red-headed flea beetle adults demonstrated a similar, but not statistically significant, trend, and cranberry weevil preferred neither cultivar.

Artificial neural network model proves accurate in classification study

Scientists evaluated the potential of multispectral reflectance and seven vegetation indices in the visible and near-infrared spectral range for discriminating and classifying bare soil and several horticultural irrigated crops. Results of the three classification methods studies showed that the highest percentage of accuracy was achieved with multilayer perceptron, leading the researchers to recommend that the MLP neural network model should be considered for a successful classification of remote sensed data.

Genetic Relationship between Hungarian and Turkish Apricots Confirmed

E-mail Print

Molecular evidence supports long-suspected historical connection

Apricots are important to Turkey, the country where more apricot crops are grown and exported than anywhere in the world. Looking to unlock the mystery of apricots' origins and increase crop production, scientists are studying the genetic relationship between apricot varieties. New research from a team of Hungarian and Turkish scientists has confirmed the genetic link between Turkish and Hungarian apricot cultivars, yielding information that provides valuable data for apricot growers and breeders.

Genetic Origin of Cultivated Citrus Determined

Researchers find evidence of origins of orange, lime, lemon, grapefruit, other citrus species

Even with a documented history of cultivation spanning more than 4,000 years, the exact genetic origins of cultivated Citrus species such as sweet orange, lemon, and grapefruit have remained obscure. Chinese researchers used a combination of analyzed amplified fragment length polymorphism (AFLP) and Chloroplast DNA data to identify the exact genetic origin of cultivated citrus. The molecular evidence presented the most convincing data to date in support the origin of lime.
