现代水稻品种所需要改良的遗传性状往往与不良性状连锁。例如抗螟虫的水稻品系可能感染稻瘟病。或者高蛋白质含量的水稻可能产量很差。这就是为什么在现代育种规划中必须有很大的杂交数月,以便充分地开拓水稻的遗传潜力。科学工作者必须将良好的植株性状综合到品系中去,而这些品系在特定的环境和气候条件下有良好的产量。小花的去雄一直是育种规划里进行细致而大量操作中的障碍。这种化时间的工作必须集中在一个短时期内完成的。稻穗上每一朵小花必须剪短,并用镊子去除花药(雄蕊), The genetic traits that need to be improved in modern rice varieties are often linked to poor traits. For example, rice stems resistant to rice stem borers may be affected by rice stem borers. Or high protein content of rice may yield poor. This is why there must be a great number of months of hybridization in modern breeding programs in order to fully exploit the genetic potential of rice. Scientists must incorporate good plant traits into the lines, which have good yields under specific environmental and climatic conditions. The removal of florets has been an obstacle in the elaboration and extensive operation of breeding programs. This kind of time work must be concentrated in a short period of time to complete. Each flower on the ear of rice must be cut short and tweezers to remove anthers (stamens)
