Abstract

Forty-five potato varieties representative of a wide range of vine types were utilized in studies with the following objectives:

1. To determine potato varietal characteristics in water usage,

2. To determine the immediate and protracted effects of high temperatures on potato plants,

3. To ascertain the morphological and physiological factors associated with varieties in varietal response to heat and drouth, and

4. To compare and evaluate various methods of testing potato varieties for resistance to heat and drouth.
