Small differences in protein content between varieties of spring wheat

24.1.2007

<div>The protein content of spring wheat was low in the autumn 2006 crop. Anniina stands out from the other varieties as having higher protein content than the others. The differences in protein content between the other varieties are smaller than in previous years. In other grains the differences in protein content were on the same level as in previous years. </div>

Anniina differs clearly from other spring wheat varieties by its protein content. The average protein content of Anniina is 14.1 %, while for the other varieties it varied between 12.6 in Tjalve to 11.9 per cent in Amaretto. Also the wet gluten percentage and Zeleny index that are dependent on the protein content are higher in Anniina, respectively 28.8 % and 60. The highest hectolitre weights were found in Triso (84.1 kg), Zebra (83.6 kg) and Amaretto (83.4 kg). The falling numbers were high in all of the varieties. The lowest averages, which were found in Amaretto and Vinjett, were 284. 

In the winter wheats, the highest average protein content was found in Urho (12.4 %). The protein content of Olivin was somewhat lower than the others (11.6 %), but the hectolitre weight was the highest (81.9 kg). The lowest hectolitre weights were found in Urho (80.6 kg) and Tryggve (80.8 kg). Also the average falling numbers for winter wheat were very high.

Due to the high protein content, the samples fulfilling the quality requirements for spring wheat (hectolitre weight ≥78 kg, protein ≥12.5 %, falling number ≥180) were found mostly in Anniina, at 79 per cent. The varieties with the next highest samples of milling quality were Tjalve (52.6 %) and Mahti (40.9). Of the winter wheat varieties most samples of milling quality were found in Gunbo (57 %) and Urho (42 %).

Of the rye varieties, the highest average hectolitre weights were found in Elvi (78.8 kg), Akusti (78.7 kg) and Amilo (78.4 kg). The lowest were found in Voima (74.1 kg) and Kartano (75.3 kg). The highest falling numbers were found in Amilo (255) and Akusti (225) while the others were quite close to each other (193 - 212). The highest level of shrivelled grains was found in Akusti (6.2 %) and the lowest in Amilo (0.9 %).

Of the malting barley samples intended for malting barley, the lowest protein content was found in Annabell (11.3 %) and the highest in Barke (12.4 %). The lowest hectolitre weight was found in Saana (71.2 kg), while the other varieties (72.3 - 72.6 kg), were very close to one another. Also the sieving (>2.5 mm) was a little lower for Saana (93.5 %) than for other varieties (95.2 - 95.7 %).

The highest average hectolitre weights for the barley varieties were found in Inari (71.0 kg) and Edel (69.6 kg). The lowest were found in Artturi (64.5 kg) and Rolfi (65.4 kg). Also the percentage of shrivelled grains (≤2.0 mm) was highest in Artturi (5.5 %). The lowest percentages were found in Inari and Jyvä (both 0.8 %). The protein content was highest in Artturi (13.1 %) and lowest in Kunnari (11.2 %) and Edel (11.3 %).

In the oats, the percentage of samples that had a hectolitre weight above 58 kilograms was highest in Leila (38.7 %) and Suomi (32.6 %). Also the average hectolitre weight was the highest for these varieties. The lowest percentages and average hectolitre weights were found in Aarre (11.1 % and 54.4 kg) and Roope (11.6 % and 54.3 kg). The percentage of shrivelled grains (≤2.0 mm) was somewhat higher than normally. The lowest percentages were found in Salo (8.8 %) and Leila (10.1 %) and the highest in Roope (15.2 %) and Veli (14.9 %).
