A Review of Research Progress in Rice Anther Culture.

Area of Science:

• Plant breeding and genetics
• Agricultural biotechnology

Background:

• Conventional rice breeding requires 8-10 generations for stable homozygous lines.
• Haploid breeding offers a faster alternative, producing doubled haploid (DH) lines in a single generation.

Purpose of the Study:

• To systematically review research progress in rice anther culture for haploid breeding.
• To focus on the steps, applications, history, efficiency factors, challenges, and future of rice anther culture.

Main Methods:

• Review of existing literature on rice anther culture and haploid breeding.
• Analysis of factors influencing anther culture efficiency and genetic mechanisms.

Main Results:

• Anther culture is the primary method for haploid induction in rice due to its mature protocol.
• Efficient haploid induction is critical for the success of haploid breeding.

Conclusions:

• Haploid breeding, particularly via anther culture, substantially shortens the rice breeding cycle.
• Understanding and optimizing anther culture efficiency is crucial for advancing rice genetic improvement.
