What Is an Improved Variety?

Today’s forage research is very interesting. Some forages, such as alfalfa, are highly researched by many private, public and non-profit groups and
are being significantly improved year to year.
Other forages, such as white (ladino) clover and red clover, are also extensively researched. New varieties come out almost every year. Most other
forages are also going through several research programs.
How is basic research done of forages to make them better?
Let’s take alfalfa, for example, and we want to create a more drought tolerant variety. Individual plants are planted in a plot. The plants mature.
Then during the driest period during that season (before plant pollination), the researcher goes through the plot and kills the plants that are
struggling the most with the lack of moisture. The plants that are the most tolerant of the dry conditions are then allow to pollinate. Seed from
those plants is harvested and replanted the next year, and the process is repeated. Over time, the most drought tolerant genes become dominant, and
after many years of replicating the process, a new variety is created that shows more drought tolerance.
The research/breeding process to create a new, improved variety may take six years or longer. So the process of creating a new forage variety is
painstakingly slow.
One thing is certain, some of the latest improved varieties are far superior to the old, cheap stuff. For example, plant Crescendo ladino next to
the cheapest ladino clover you can find. The difference is very noticeable, especially after several years. Plant a quality alfalfa next to the
cheapest alfalfa, and you will be shocked by the difference in performance.
