刍议优质两系杂交早稻组合的选育

根据现阶段育种和生产现状，提出了两系杂交早稻品质育种目标。针对垩白、直链淀粉含量等品质性状的遗传表现规律，探讨了两系杂交早稻品质改良的技术特点，并提出了加速实用型早熟优质两用核不育系选育、协调好优质与高产的关系、创建理想株型、针对不育系特点选择父本配组等育种对策

Dealing with the High Quality Breeding of Two Line Hybrid Rice for Early Season

The targets of high-quality breeding of two-line hybrid rice for early season are put forward according to the status of breeding and field production at present. After synthesizing the hereditary law of major quality characteristics such as chalkiness, amylose content etc, the main points of techniques are discussed for quality amelioration of two-line hybrid rice. Then, the breeding strategy is suggested as that accelerating the improvement of practical T/PGMS, harmonizing the relationship between high quality and high yield. building ideal plant type, selecting ideal pollen parent according to the T/PGMS′ character and so on.
