웅성불임성을 이용한 효율적인 F₁ 양파 품종 개발

Onion is agronomically very important plant in the world and difficult to develop variety due to life cycle of biannual crop. For that reason, breeding period of new elite line need approximately fifteen years and breeding time is longer than other annual crop. To develop efficient F₁ variety in onion, onion breeder need to understand interaction between cytoplasm and nuclear about cytoplasmic male sterility and restorer of fertility respectively. Use of previously developed molecular markers is essential to utilize this system and breed elite lines efficiently. application of this molecular markers to be able to recognize cytoplasmic male sterility type and restorer of fertility gene in onion breeding are possible to reduce breeding period and able to classify lines without testcross according propose such as ms and maintainer lines. CMS and Rf system of onion scribed in this paper will be utilized in onion breeding program to efficient F₁ variety development.
