Experiments with peas-
Rough or smooth
•Gregor Mendel found that the pea plant has
some traits which come in pairs. Like the seed
is either rough or smooth.
•It is either green or yellow, either tall or short.
Nothing in between.
•For seven years he did experiments on 28000
plants in garden of the monastery. He worked
hard, collected many observations and made a
new discovery!

Gregor Mendel
Gregor Johann Mendel (July 20,
1822 –January 6, 1884) was an
Austrianscientistand Augustinian
friarwho gained posthumous fame
as the founder of the new science of
genetics. Mendel demonstrated
that the inheritanceof certain
traitsin peaplants follows
particular patterns, now referred
to as the laws of Mendelian
inheritance. Although the
significance of Mendel's work was
not recognized until the turn of the
20th century, the independent
rediscovery of these laws formed
the foundation of the modern
science of genetics.

Rough peas
This plant, native to the Mediterranean
region, is a winter annual adapted to the
southern third of the United States. The stems
are weak and trailing except in dense stands.
The leaves have one pair of long, narrow
leaflets and terminate in a coiled tendril. The
seed pods are rough and hairy. Seeds are
usually sown in the fall. Plantings are used for
pasture, for hay, or for turning under for soil
improvement. Livestock may be injured from
grazing plants with mature seeds or feeding
hay from such plants, but prior to seed
ripening good pasturage and hay are
produced. Growing of rough pea has declined
greatly in recent years as Austrian winter peas
and hairy vetch make more growth. Acreage
harvested for seed was 34,631 in 1949 and
only 8,109 in 1959, according to census
figures.

Smooth peas
Smooth peas, wrinkled peas and
garbanzo beans were evaluated
for production of sweetened
paste with regard to yield and
quality. Wrinkled peas required
longer cooking times (6.5 h and
5.5 h) than smooth peas (2.5 h)
and garbanzo beans (3.5 h). The
yield of fine cotyledon particles
which were used for production
of sweetened paste was 65.8%
for garbanzo bean cv. Sanford,
63.2% for smooth pea cv.
Columbian, but only 33.7% for
wrinkled pea cv.
