標記與水稻雜種產量及產量雜種優勢的預測Abstract : the main characters and seed set of bc1 ， bc2 ， bc1f2 from ms line back - crossing with the pollen of hybrid rice were studied. the appearance of a large number of self fertile plants in ms line was analyzed. the effect of introgression of restoring genes on ms line purity and hybrid yield in indica and japonica rice was discussed. it was pointed out that “ iso - cytoplasm restorer line ” was seriously reducing the purity of ms line and that hybrid rice was unsuitable for isolation zone in the seed production fields
文摘:研究了雜交稻花粉對母本不育系回交後代群體bc1 、 bc2 、 bc1f2的主要農藝性狀和育性表現，分析了不育系中出現大量自交結實株的原因，討論了恢復基因滲入對秈、粳不育系純度和雜交稻產量的影響，指出「同質恢」對降低不育系純度的嚴重性和雜交稻作制種田隔離區的不合理性。However, the processing quality and food quality of hybrid rice is not good due to high amylose content and hardness, low gel viscosity and bad mouthfeel etc. these problems were improved through regular breeding methods but it was only slightly. the main aim of this study was to modify rice starch quality by molecular biology methods
然而，在雜交稻中許多品種存在品質不優的問題，尤其是直鏈澱粉含量太高，其蒸煮品質上表現為粘性小，硬度大，口感不好等問題，採用常規育種的方法雖然取得了一些進展，但進程太慢，效果不理想。Analysis of heterosis in yield component traits of transgenic restorers lines

標記輔助改良熱帶粳稻利用水稻亞種間雜種優勢Genetic analysis on cold tolerance of the hybrids of near - isogenic lines from japonica lijing 2 in rice
水稻麗粳2號近等基因系雜種後代耐冷性遺傳研究Stability in early generation was first discovered in rice hybrid breeding, because it can fix genotype in early generation of hybrid, this probably made it real to cultivate a new kind of hybrid seed which could be planted for several generations
摘要早世代穩定現象首先在水稻雜交育種過程中發現，該現象可以早世代固定雜種基因型，這為培育可以多代利用的雜交種，奠定了一定的基礎。No matter hybrid rice or conventional rice varieties, erect and semi - erect panicle rice varieties were suitable for equal row spacing cultivation for intercepting mare light at canopy, while curved - panicle rice varieties were for wide - narrow row spacing cultivation for improving light intensities of middle and lower layer leaves
但不同類型品種適宜的栽培方式不同：雜交稻適宜插單苗，而常規稻適宜插3苗；不論是雜交稻還是常規稻，直立穗型和半直立穗型品種適宜等行距栽培以減少群體漏光，彎曲穗型品種適宜寬窄行栽培以改善中下層葉片的光照條件。Performance of a new hybrid rice combination yueyou 938 planted in late rice region at minqing county of fujian province in china
雜交稻新組合粵優938在閩清縣試種表現Correlation between genetic distance and yield heterosis of hybrid aromatic rice
