VARIETY IDENTIFICATION PROCEDURE

VARIETY IDENTIFICATION IS NOT DIFFICULT

Surveys show that in any one community there are usually not more than five or six varieties. With careful study of typical,pure kernel samples one can learn to recognize local varieties with a high degree of accuracy.

GUIDES IN IDENTIFYING KERNELSOF BARLEY VARIETIES

1. Study type samples - look at the sample asa whole, not at only a few individual

kernels. Line up a row of 10-20 kernelspointing the base end toward the lightsource.

2. Use a magnifier with a good strong light -north daylight is best.

3. Know which varieties are being grown inyour area - keep an eye open for any new

introductions. Study varietal kernelcharacteristics for each new crop.

4. Do not be afraid to look and look, andlook again.

TO IDENTIFY A SAMPLE

A. Check general appearance of the sample. A pure sample will usually appear uniform. A sample containing a mixture of

varieties generally has a non-uniform appearance.

B. Determine the major kernel characters as follows:

1. Six-Row or Two-Row - The lateral or sidekernels in six-row varieties are twisted.Therefore, in six-row varieties, two-thirdsof the kernels are twisted. In two-rowvarieties, which have no lateral kernels, all

kernels are straight and symmetrical andnone are twisted.

2. White or Blue pearl (aleurone) This is aneasy character to determine with the use of abarley pearling machine. Sometimes bluevarieties may have very weakly developed

4. Long or Short Hairs on Rachilla - This is an excellent character to use but a hand magnifying lens is needed

to see the rachilla hairs. The difference between long and short hairs is very pronounced and does not vary fromyear to year or in different areas. Some varieties have aborted rachillas, these can be seen readily with thenaked eye.

C. If the above characters are not sufficient to identify a variety, other characters will have to be used. The mostuseful are described below:

1. The basal mark can vary from a depression to a transverse crease. A depression is a smooth uniform hollowor dimple. A transverse crease is a sharp fold or line.

2. Crease shape may vary from wide, open and V-shaped from base of kernel to narrow and almost closed. Insome varieties the crease is closed in the bottom half of the kernel and flaring at the tip end. This character willvary with growing conditions and plumpness of kernel.

3. Barbs on lateral veins can be seen witha magnifying glass or felt with the finger.Their number varies from none to manyin different varieties. These barbs are notrelated to the barbs on the beards of roughbearded varieties.

4. Hairs on glumes require carefulobservation with a hand magnifying lensto determine the length of hairs and theirlocation on the glume. This can be a veryuseful character in varieties such as Fosterwhere the glumes are covered with longhairs.

5. Kernel shape varies with growingconditions but can be of value in a localarea. The relationship between lengthand width and fullness in different parts ofthe kernel are useful characters. Kernelshape may be smooth and tapered or there
