While black necrotic spots can indicate disease, a general brown tint to the seed coat is usually harmless. Forum experts identify several reasons for this:<\/p>\n<ul>\n<li><strong>Genetics:<\/strong> Certain varieties naturally produce darker seeds.<\/li>\n<li><strong>Nutrient Uptake:<\/strong> The chemical composition of the fruit (driven by your fertilizer regime) can alter the color of the gel sac and seed coat.<\/li>\n<li><strong>Fermentation Process:<\/strong> If you don&#8217;t add a little water to speed up fermentation, or if you ferment them too long, the seeds can stain.<\/li>\n<li><strong>Sun Baking:<\/strong> Drying freshly washed seeds in direct, hot sunlight can literally &#8220;bake&#8221; and darken the seed coat. Always dry seeds on a paper plate or screen in a shaded, well-ventilated area.<\/li>\n<\/ul>\n<p><em>Conclusion: As long as the seeds are plump and don&#8217;t have fuzzy mold or pitch-black spots, they are viable and will germinate perfectly next spring.<\/em><\/p>\n<\/div>\n<h2>\ud83d\udde3\ufe0f Forum Discussion: Are Brown Tomato Seeds Viable?<\/h2>\n<div class=\"forum-post\">\n<div class=\"author-header\">\n<div class=\"forum-avatar\">G<\/div>\n<div class=\"author-meta\">\n<div class=\"author-name\">Galiy (Galina) <span class=\"author-stats\">\u2b50 Pro Grower (17,551 posts)<\/span><\/div>\n<div class=\"author-geo\">\ud83d\udccd Moscow Region (USDA Zone 4)<\/div>\n<\/div>\n<\/div>\n<div class=\"post-content\">\n<p>Good afternoon.

I rarely browse the grow logs these days, no time at all, but I want to answer this one.<\/strong>.<\/p>\n<p>Ladies, the color of the seeds depends on several reasons, mainly TWO:<\/p>\n<ul>\n<li><strong>Varietal genetics.<\/strong><\/li>\n<li><strong>Chemical composition in the fruit<\/strong>, which is directly dependent on the fertilizers\/nutrients the plant took up.<\/li>\n<\/ul>\n<p>Because of this, the pulp and the seed coat can change color when the seeds are dried. A light brown color is totally normal for some varieties.<\/p>\n<p>There is another minor factor affecting the color of dried seeds \u2014 a violation of the processing technology, if you can call it that. After the seeds are scooped out, you need to add a little water for faster fermentation. A proper fermentation and rinsing process washes all those trace elements off the surface of the seed.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/galleries\/77\/4712-220715103313.jpeg\" \/><\/p>\n<p><strong>One more crucial point:<\/strong> You must NOT dry the seeds in direct sunlight after washing off the gel pulp.
