Polyploidy – or how do we get seedless fruit?

Having an odd number of chromosomes can produce sterile – and seedless fruit

May 7, 2019 – Spitting out watermelon seeds can be a summertime rite of passage for some folks. Others like their watermelons seedless. How did those seedless watermelons (and other plants) come about? The May 7thSustainable, Secure Food blog explains the topic of polyploidy.

“Plants can have multiple sets of chromosomes, which is called polyploidy. Many of your favorite fruits and vegetables are polyploids,” says blogger and plant scientist, Christine Bradish, Ashland, Inc. “Polyploidy can occur naturally, where wild species “add together” their DNA.  Two good examples of this are wheat and strawberries.”

But, plant breeders can also develop work to develop crops without seeds – like seedless watermelons. Even bananas are seedless.

“Polyploidy is one more tool that scientists can use to learn about the genetics of crop plants,” says Bradish. To read the complete blog, visit Sustainable, Secure Food at https://sustainable-secure-food-blog.com/2019/05/07/polyploidy-or-how-do-we-get-seedless-fruit
