陆地棉 光敏雄性不育 基因控制 隐性性状
2024/4/16
陆地棉光敏雄性不育系中9106是在中040029的后代中发现的突变体，它在长日照（河南安阳）条件下表现为彻底的雄性不育。以陆地棉乐土603、TM-1和海岛棉海7124为父本分别配置F2杂交组合发现中9106的雄性不育性状是受一对核基因控制的隐性性状。利用以全基因组测序为基础的分离群体群分法和以中9106×TM-1的F2群体进行的图位克隆，将中9106的雄性不育基因定位在D12染色体上QZD84和Q...
Incorporation of parental phenotypic data into multi-omic models improves prediction of yield-related traits in hybrid rice

Hybrid breeding has been shown to effectively increase rice productivity. However, identifying desirable hybrids out of numerous potential combinations is a daunting challenge. Genomic selection holds...
Differential response of maize hybrid and its parental lines to salinity stress
antioxidant enzymes Na+ proline salinity stress sugars Zea mays L.

Sterility of Thermo-Sensitive Genic Male Sterile Line,Heterosis for Grain Yield and Related Characters in F1 Hybrid Rice (Oryza sativa L.)
Dry matter F1 hybrid Grain yield Heterosis Sterility
2009/7/28
The thermo-sensitive genic male sterile (TGMS) T29s line was sterile when exposed to daily mean temperatures of 24.1°C or above during the critical stage (from 15 to 11 days before heading). It was co...
Broadening the genetic base of crop brassicas by production of new intergeneric hybrid
Brassica oleracea var.alboglabra embryo-rescue Erucastrum cardaminoides genetic variability wide hybridization
2014/3/11
Wide hybridization between crop brassicas and their wild relatives is an important approach towards increasing the genetic variability, which can be utilised for brassica breeding programs. A new inte...

Interspecific germplasm introgression enables unique opportunities for genetic analysis and improvement of domesticated plants, but is commonly impeded by barriers to transmission and recombination, i...
中籼杂交水稻亲本多态性的AFLP分析Polymorphisms in Semilate indica Hybrid Rice as Revealed by AFLPs
中籼杂交稻 AFLP 遗传距离
2007/12/29
对15个籼型杂交水稻亲本进行AFLP分析，结果表明：亲本间遗传距离小，在0.0589~0.3305之间，平均为0.2033。15个亲本按类平均法可聚为两类，Ⅰ类为不育系，Ⅱ类为恢复系。其中Ⅱ类又分为两个亚类，Ⅱ-1不含明恢63血缘、Ⅱ-2全部含明恢63血缘。Ⅰ/Ⅱ-1与Ⅰ/Ⅱ-2间的遗传距离无明显差异，揭示恢复系的遗传基础较一致，这可能是当前的品种不能超过汕优63的重要原因之一。要提高水稻的杂种优...
