Effect of opaque-2 Gene on Grain,Quality and Popping Characteristics of Popcorn
Abstract：In this study,opaque-2 (o2) gene was transferred into two popcorn inbred lines by marker-assisted selection technique,and the effects of o2 gene on grain,quality and popping characteristics were analyzed in popcorn. The results showed that the o2 gene could be effectively transferred into popcorn in-bred lines by marker-assisted selection technique. In the BC3 F2 population,crude protein content of pop-corn with o2 gene was reduced by 0. 34%—3. 97% compared with that of wild type,popping volume de-creased by 17. 50—96. 50mL,popping rate reduced by 25. 00%—98. 00%, popping fold decreased by 1. 50—10. 24 mL/g. But the other traits were less affected by o2 gene. Therefore,the crude protein con-tent and popping characteristics were influenced significantly by o2 gene in popcorn.
