Abstract

A single recessive gene, Multi-Grain Spikelet 1 (MGS1), governs the multiple-grain spikelet trait in sorghum. The natural variants mgs1 and mgs1 trigger adjacent double-pistil primordia, significantly boosting grain numbers per panicle, suggesting potential strategies for breeding high-yield sorghum.

摘要

一个隐性基因，多粒小穗1（MGS1），控制着高粱的多粒小穗性状。自然变异体mgs1和mgs1引发相邻的双雌蕊原基，显著增加每穗粒数，为高产高粱育种提供了潜在策略。
