1 Food Plants

2 For Love of the Potato

3 The Potato Comes to Europe The potato came to Europe about 1565 - at first, most people in Europe, including the Irish, used the potato as a back up for grain production, but by the end of the 17th century, it had become an important winter food; by the mid-eighteenth century it was a general field crop and provided the staple diet of small farmers during most of the year

14 Cartoon of Irish “Bogtrotters” circa 1840’s

15 Irish family digging Potatoes - 1847

16 Irish family potato dinner - 1846

17 Irish food riots - 1847

18 Irish food sent to England – 1847 or 1848

19 Lessons learned? “Whatever may be the misfortunes of Ireland, the potato is not implicated. It, on the contrary, has more than done its duty, in giving them bones and sinew cheap... There is no other crop equal to the potato in the power of sustaining life and health.” - Bain 1848

20 Ethnobotany and Domesticated Plants Wheat

21 First ethnobotanical rule of food production In indigenous agriculture where the crops are consumed and not sold, there evolves and is maintained a reasonable level of nutritional adequacy

22 Second ethnobotanical rule of food production In indigenous agriculture where the crops are grown mainly or only for sale, there develops an expanding surplus of food. The overall objective of such agricultural systems is to replace a pre-existing (natural) plant community with a cultivator-made community

23 It then follows that: If the potentially unstable increase in food production and human population is to be maintained, it must be consistent with three aims: 1. To operate at a maximum profit (labor/yield). 2. To minimize year-to-year instability in production. 3. To operate so as to prevent long-term degradation of the production capacity of the agricultural system.

25 Darwin on Artificial Selection “Although man did not cause variability and cannot even prevent it, he can select, preserve, and accumulate the variations given to him by the hand of nature almost in any way which he chooses; and thus can certainly produce a great result… Selection by man may be followed either methodically and intentionally, or unconsciously and unintentionally… We can further understand how it is that domestic races of plants often exhibit an abnormal character, as compared to natural species, for they have been modified not for their own benefit, but for that of man.”

30 Plant Germ Plasm The first category of germ plasm includes the native or indigenous varieties of cultivated crop plants used elsewhere in commercial agricultural production. At present many of the major crop plants have a limited genetic base, as these have been developed through a series of selections that emphasize yield often at the expense of insect or disease resistance, environmental tolerance, multiple use, etc.

42 Plant Germ Plasm The second category of germ plasm material includes the identification and collection of wild relatives of the more commonly cultivated plants.

43 Wild Tomato Species Genus Lycoperiscon Domestic High Altitude Another L. chmielewskii

44 Plant Germ Plasm The third category includes plants not yet in the economic system and not related to domesticated plants. These may have properties of great value to us, but these can be very difficult to identify.
