Identification of Heterotic Groups and Patterns Based on Genotypic and Phenotypic Characteristics Among Rice Accessions of Diverse Origins
heterotic groups heterotic patterns hybrid rice SNP accession genetic distance
2023/4/21
Identification of the right parental combinations to maximize heterosis is the major goal of hybrid breeding, which could be achieved through identification of heterotic groups. The main objective of ...
Identification of an active 1Ay gene from Triticum turgidum ssp. dicoccoides
1Ay gene high molecular weight glutenin subunit (HMW-GS) phylogenetic analysis wild emmer wheat
2014/9/22
The high molecular weight glutenin subunit (HMW-GS), encoded by the 1Ay gene, unexpressed in common wheat, exists in diploid and tetraploid wheats. An active 1Ay gene was first cloned from wild emmer ...
In vitro mutagenesis and identification of new variants via RAPD markers for improving Chrysanthemum morifolium
Chrysanthemum morifolium in vitro mutagenesis RAPD analysis somaclones
2011/1/11
The objective of this study was to induce mutation in Chrysanthemum morifolium cv. ‘Delistar White’ through in vitro mutagenesis by treating the ray florets with two doses of gamma irradiation (0.5 an...

The objective of this study was to establish the technology to identify wheat and barley cultivars by random amplified polymorphic DNA(RAPD) analysis to improve the quality of wheat and barley in Toch...
Self-compatibility of 3 Apple Cultivars and Identification of S-allele Genotypes in Their Self-pollinated Progenies
embryo culture parthenocarpy X-ray irradiated
2009/7/7
We analyzed fruit and seed sets after self-pollination in 3 apple cultivars. Between 1998 and 2001, we carried out self-pollination of cultivars ‘Megumi’, ‘Orin’ and ‘Fuji’, which exhibit different le...
Identification of a Herbicide Safener AD-67 Inducible cDNA in Rice
rice chemical induction cDNA mRNA differential display herbicide safener
2008/12/11
A herbicide safener AD-67 inducible cDNA was identified in an indica rice variety 9311 by mRNA differential display. The transcript was increased 6 h after sprayed with the safener solution, and 4 day...
小黑麦×小滨麦后代1RS·1BL易位系的选育和鉴定Development and Molecular Cytogenetic Identification of 1RS·1BL Translocation lines derived from Triticale×Tritileymus
小黑麦 小滨麦 1RS·1BL易位系 原位杂交 分带
2008/1/8
摘要
利用细胞学、染色体C分带和原位杂交方法，对八倍体小黑麦劲松49与八倍体小滨麦杂种后代选育的稳定遗传材料山农030-1进行了鉴定。染色体观察结果表明，山农030-1根尖染色体数目为42，花粉母细胞减数分裂中期I(PMC MI)染色体构型为2ｎ=21Ⅱ。分别以黑麦、滨麦草基因组DNA为探针进行原位杂交，表明山农030-1含有一对黑麦和小麦的整臂易位染色体，不含有来自滨麦草的遗传物质。染色体C分...
