Course Outline for BTSC., 854 

?

(81-3) 

1. ? 

Systems: 

Patterns; systems levels, Gestalt principle, auboptimisation. 

Structure and behaviour; control of behaviour, cybeinetice, genetic 

code, behaviour patterns, behaviour strategies. 

2. ? 

Ecosystems' 

Boundaries; geographical, biological, conceptual. 

?

Evolution 

of behaviour; ESS. 

?

K-strategists cause endemics characterized by 

continuity in space and time; r-strategists cause epidemics chara- 

cterized by discontinuity. 

'. ? 

Pathosystems 

Subsystem of an ecosystem; parasitism. 

?

Plant pathosystems; 

wild, crop and weed pathosystems. 

?

Hosts as islands; migration to 

islands (állo-infection) and colonization of islands (auto-infection). 

Subsystems of. pathosystems of pathosyatems; vertical, horizontal, 

others. 

4'.. 

?

Vertical Subsystem: 

Vertical resistance. 

?

Gene-for-gem relationship, Person/Habgood 

differential interaction, control of exodemic only. 

?

Discontinuity 

in time and space; r-strategists and epidemics only. 

?

Host and key 

analogy. ? 

Models, examples. 

5.

Horizontal Subsyst: 

Horizontal resistance. No gene-for-gene relationship, constant 

ranking; control of esodemic (auto-infection). 

Models; 

examples; 

permanence. 

6.

Wild Pathosystems: 

Autonomous, balanced; ESS. Models of vertical and horizontal 

subsystems and their inter-relationships. Examples. 

7.

Crop Pathosystems: 

• ? 

Uniformity. Suboptimisation of vertical subsystem and within 

vertical subsystem. Boom and bust cycles. The influence of Mendel 

and Biff in. Gene-transfer methodologies and pedigree breeding. 

• ? 

Examples. Weed pathosystems. 

8.

Pathosyatetn Management: 

Vertical subsystem management. Horizontal subsystem management. 

Breeding plunta for resistance which is permanent, complete and 

comprehensive. 

9 ?

Overvcw' the world food problem, cause and solution. 

New Graduate Course Proposal: - Plant Pathosystee SISC 854 

Appendix: 

a)

Outline.of the course: The systems concept; ecosystems; plant 

pathosyatems; vertical and horizontal subsystems; models of 

wild pathosyatems and their subsystems; the crop pathosystem; 

breeding for horizontal resistance to crop and forest parasites; 

breeding of perennial hosts; breeding of annual hosts; world 

food production and the world food problem. 

b) Competence: The faculty member is author of a book entitled 

"Plant Pathosystema" and the course is based on this book. 

c)

Library resources: Already adequate.
