Hello, my name is Roberto Tuberosa,
and I teach plant biotechnology
applied to plant breeding at the
University of Bologna in Italy.
My research interests focus
mainly on maize and durum wheat,
also known as pasta
wheat, durum wheat.
My lecture will touch upon
a number of important issues
to better understand and appreciate
the roles that modern genetics will
play to select more
climate-resilient crop cultivars,
better able to adapt to a
fast changing environment.
It has been estimated
that approximately 70%
of the increase in food production
that will be required to meet
an adequate level of food
security by year 2050,
will derive from
genetics approaches.
Particularly genomics applied
to combination of breeding.

The contents of this
lecture partially
overlap and expand
those of other lectures.
Particularly the one provided by
Professor Henry, Professor Tester,
Professor Paterson,
and Professor King.
But also provide useful information
and material for a number of issues
important to mitigate the
consequences of climate change
on agriculture by a
genetics approach.
In view of the vastity and
complexity of the issue started
by my lecture, I will only
focus on the limited number
of aspects and examples.
I will start by setting the stage
for a number of important issues
and aspects, including also some
dos and don'ts as related to both
conventional breeding,
and to molecular breeding,
also known as genomics
assisted breeding.
Due to the fact that most traits
that regulate the adaptive response
of the plant are
quantitative, the QTL approach
will be dealt with quite
extensively in this lecture,
with some examples from my own
lab, and also from the literature.
Finally, I will provide some
comments on the future challenges
and opportunities to best
mitigate the negative effects
of climate change.
