Two-line hybrid rice seed production

摘要

The production of two-line rice hybrids involves two major steps: (1) multiplication of EGMS lines and (2) hybrid rice seed production. Each of these steps requires specific environmental conditions for seed production. Therefore, the locations/seasons for producing the two types of seed have to be different. In Chapter 5, we suggested that suitable specific locations must be identified for elite EGMS lines for their self seed multiplication. Locations must also be identified that are suitable for hybrid seed production using the same EGMS lines.
