Abstract
The effects of growth temperature on seed color of two black- and four yellow-seeded doubled-haploid genotypes of Brassica napus were examined with plants grown at 16/12, 18/14, 20/16, 22/18 and 24/20 °C (day/night). High temperatures significantly reduced seed color that developed on yellow-seeded genotypes but did not alter seed color produced on black-seeded genotypes. The decrease in pigmentation measured with a modified near-infrared reflectance analyzer was linearly related to temperature for the yellow-seeded genotypes. Significant differences in the magnitudes of the response were observed among the yellow-seeded genotypes. This is the first systematic study of temperature effects on seed color in rapeseed. The results confirm previous preliminary reports of environmental modifications of this trait. The study also illustrates a method for determining temperature effects on seed-color expressivity that may be useful for plant breeding programs. Key words: Temperature, Brassica napus, seed color
