Sensako, Pannar and the ARC-Small
Grain Institute. Despite the heat
and drought, a considerable number of cultivars still produced profitable yields. These results once again
highlighted the importance of good
cultivar choice for successful irrigation wheat production in South Africa, as well as the importance of
cultivar evaluation.
workgroup on 11 February 2016.
The report was accepted and the
new recommendations for the 2016
season were finalised. In the following section, the yields of early
planted irrigation cultivars in the
different areas are presented. Four
year average yields for the cultivars
are also provided to give an indication of the yield stability.
The cultivar evaluation trials were
carried out in the cooler central irrigation areas, the wWarmer northern irrigation areas, KwaZulu-Natal
and the Highveld. The results of the
2015 cultivar trials under irrigation
were presented to the National
Wheat Cultivar Adaptation
CULTIVAR EVALUATION RESULTS
Cooler Central Irrigation areas
The average yield for the first plantings in the cooler central irrigation
areas in 2015 was 9.11 ton/ha. PAN
3400 (9.90 ton/ha), SST 8125 (9.74
ton/ha), SST 806 (9.70 ton/ha) and
SST 835 (9.56 ton/ha) produced the
highest yields (Table 1). Average
hectolitre mass was good in 2015
at 82.52 kg/hl. All cultivars had a
hectolitre mass above 77 kg/hl.
Grain protein content was also acceptable at 12.61%. Falling number
values were high, with an average
of 341 seconds. The four year average grain yields indicate that SST
806 produced the highest yield
(9.48 ton/ha), followed by SST 835
(9.47 ton/ha), PAN 3400 (9.45 ton/
ha), PAN 3497 (9.41 ton/ha) and
SST 884 (9.40 ton/ha) (Figure 2). It
should be noted that the yields of
these five cultivars were not significantly different from each other.
