Plans for 2011
The
number of Demonstration plots sown in mid-October 2010 was increased
to 60 accessions (Table 1). This includes a number of newly acquired or
verified ‘Heritage’ lines. Each 1m2 plot was sown at low density
and the plots will be grown free of growth regulators and with minimal
fungicides and reduced nitrogen. Characterisation of the material will be
undertaken throughout the growing season along with an assessment of
lodging.

As previously,
the plots will be available for viewing by prior appointment either as
individual or group visits. In addition, an open day will be organised
where interested parties will have the opportunity to view the plots with a
view to identifying any material of potential interest that they might care
to grow and evaluate for themselves. This initiative will be publicised in
the farming and local press. Anyone interested is encouraged to contact us
to arrange viewing and inspection of the material with a view to requesting
small quantities for their own evaluation following harvesting and
processing.
Lodging resistance
Lodging of each line is assessed at the
point when the nodes are still green but the stems are turning yellow
(nominal harvest time for thatching). While the same lines are not grown
each year, there is a sufficient overlap of lines each year to make looking
at the scores across years meaningful. The results have highlighted a
higher than anticipated level of reproducibility in scores (Table 2).
Clearly some years are more discriminating than others. 2009 was
particularly good at drawing out the differences in performance whereas
2010 was more benign so no severe lodging was recorded. The lines that
demonstrate a resistance to lodging can clearly be seen at the head of the
table (acc. W511, W517 and W5623). The poorest performers falling to the
bottom of the table include W3, W990 and W994. Care should be exercised
when evaluating these results in that some of the lines are more spring
types but were sown in the autumn so this might not reflect their
performance at different times of year. Secondly, these are small
unreplicated plots that were supported on the outside to facilitate viewing
and observation. Nevertheless, despite these caveats, there is clear
evidence of line variation in lodging scores. This analysis will be updated
at the end of the 2011 season to enable judgements to be made as to risks
associated with some of the material with respect to lodging.
Table
2. Lodging scores for a range of heritage bread wheats at nominal
‘harvesting time’. Lines ranked in ascending order of scores in 2009, 2010
and 2008. Scores 1 – 9 where 1= upright and 9= severely lodged. Green= 1 -
2, orange=3 - 5, Red=6 - 9. Grey boxes indicate the line was not grown in
that year.

Another useful analysis that can be
performed is to explore the relationship between canopy height (height to
the top the peduncle) at maturity and lodging. A graph of the data for 2009
(Fig 1) which showed a wide range of lodging scores, shows clearly that
canopy heights below 120cm were resistant to lodging (scores 1 and 20
whereas heights above this were prone to lodge. Heights of around 130cm had
the most variable scores but the data across years presented in table 2
suggests that some lines with canopy heights in this range might exhibit a
degree of resistance to lodging. The same health warning on this analysis
as applies to the lodging scores.
