Eastern India is an area with a largely agrarian society and high poverty incidence. Rice is the dominant crop, but yields are low. Most of the rice is grown under rainfed conditions in which rainfall...
Rice palatability correlates with amylose content, which correlates with heading date, showing that indirect selection through low amylose content for high palatability usually results in predominan...
The genetic background of the 229 ‘Kanto’ lines developed by National Institute of Crop Science was studied. Cluster analysis based on coefficients of parentage among the ‘Kanto’ lines revealed the p...
The pedigree of breeding lines of rice in Fukushima Agricultural Experiment Station (breeding lines) and cultivars (comparative varieties) in Fukushima Prefecture was analyzed. The ancestors making ...
A large number of new varieties, especially hybrid rice, have been developed and released in China since 1998. The yield potential and grain quality of hybrid rice have also been improved significantl...
Research on hybrid rice in Jiangsu Province, China began in 1970. Great progress has been made since then, which can be divided into three stages according to the development of hybrid rice breeding a...
The full-length of intact Zea mays gene for phosphoenolpyruvate carboxylase gene (ZmC4Ppc) is 6 781 bp. The products of PCR for this gene were not clear with poor repeatability, resulting in that it w...
The great progress in super rice breeding both in China and other countries has been made in recent years. However, there were three main problems in super rice breeding: 1) the super rice varieties w...
为探讨空间条件对水稻育种的影响,利用返回式卫星搭载水稻干种子,返地种植,考察分析了12个亲本品种后代的性状表现及遗传与变异情况。结果表明:空间条件诱变的后代性状具有多样性变异和多向性遗传,且能稳定遗传,并有超亲遗传现象,诱变后代具有变异类型多、变异频率高、特殊突变体、育种周期短等特点。为进一步开发利用空间技术育种,在研究实践的基础上,提出了程序化、规范化、可操作性强的水稻空间育种技术规范。
