	EVALUATION OF SEED PHYSICAL TRAITS IN RELATION TO HEAT TOLERANCE IN UPLAND COTTON HAFEEZ-UR-RAHMAN^1, SAEED AHMAD MALIK ², MUHAMMAD SALEEM³ AND FARRUKH HUSSAIN⁴ Abstract: Studies was carried out to study the effect of high temperature regimes on the phenotypic expression of physical seed traits in relation to heat tolerance in upland cotton and to determine their relationship with seed cotton yield in the presence and absence of heat stress. There was differential response of cultivars in the expression of these traits across temperature regimes which suggested that the expression of these traits in the presence of heat-stress could be useful in differentiating relatively heat tolerant and sensitive cultivars in upland cotton.
