马铃薯物种起源有新发现

Core Viewpoint - The research conducted by the team led by Huang Sanwen from the Shenzhen Agricultural Genomics Institute reveals the origin, diversity formation, and genetic mechanisms of potatoes, highlighting a significant breakthrough in the "Excellent Potato Project" aimed at transforming potato breeding methods from asexual reproduction to sexual reproduction [1]. Group 1: Research Findings - Potatoes originated from an ancient hybridization event between the tomato group and the Solanum group approximately 9 million years ago, resulting in the formation of tubers [1]. - The "Excellent Potato Project" aims to enhance breeding efficiency by shifting from traditional asexual reproduction, which requires 200 kilograms of seed potatoes per acre, to sexual reproduction that only requires 2 grams of seeds per acre [1].
