## Abstract

A method for predicting the storage ability of sugar beet roots quantifies the mechanical resistance of the root of the sugar beet. A method develops sugar beets with improved resistance, and sugar beets are obtained by this method.

## Claims

### Claim 1

A method for predicting sugar beet resistance to factors causing root damages and/or to factors causing sucrose loss upon storage, comprising quantifying mechanical resistance of a root of a sugar beet.

### Claim 2

A method for predicting sugar beet resistance to biological factors causing root damages during culture, comprising quantifying mechanical resistance of a root of sugar beets from a same genetic origin.

### Claim 3 (depends on 1)

The method of claim 1, wherein the quantification is carried out by penetrometry.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the quantification is carried out upon recording force (kg/cm2) needed to push a probe of a given section through an outer layer of the root.

### Claim 5 (depends on 4)

The method according to claim 4, wherein the quantification is a maximal force (kg/cm2) needed to push the probe of a given section through the root.

### Claim 6 (depends on 5)

The method according to claim 5, wherein the sugar beets from several origins are stratified in function of the mechanical resistance of the root of the sugar beets and/or in function of the maximal force needed to push the probe through the root.

### Claim 7 (depends on 6)

The method of claim 6, wherein the less resistant sugar beet lots are processed firstly by sugar refineries.

### Claim 8 (depends on 6)

The method of claim 6, wherein less resistant sugar beet lots are treated for reducing sucrose losses.

### Claim 9 (depends on 1)

The method according to claim 1, wherein factors leading to root damages are sugar beet pathogens and/or parasites, selected from the group consisting of bacteria, fungi, nematodes and larvae thereof, arthropods and larvae thereof, insects and larvae thereof.

### Claim 10

A method for improving resistance to damage upon storage of a sugar beet comprising the steps of: obtaining sugar beets from different genetic origins, stratifying said obtained sugar beets according to mechanical resistance of a root of said sugar beet from different origins, and selecting most resistant sugar beets.

### Claim 11

A method for improving resistance of a sugar beet to biological factors causing root damage, comprising the steps of: obtaining sugar beets from different genetic origins, stratifying said obtained sugar beets according to mechanical resistance of a root of the sugar beet from different origins, and selecting most resistant sugar beets.

### Claim 12 (depends on 10)

The method of claim 10, wherein the mechanical resistance of the root is measured.

### Claim 13 (depends on 10)

The method according to claim 10 further comprising the step of crossing selected more resistant beets from two different origins.

### Claim 14 (depends on 13)

A sugar beet, or parts thereof, obtainable by the method of claim 13.

### Claim 15

A method of using a penetrometer comprising sorting sugar beets according to resistance to sucrose loss upon storage.
