Genetic variation in MYB5_A12 is associated with fibre initiation and elongation in tetraploid cotton
MYB5_A12 陆地棉 纤维起始 纤维伸长 表达水平 海岛棉
2024/5/17
本研究发现MYB5_A12在陆地棉（SG747）纤维起始及伸长早期的表达水平显著低于海岛棉（GZ75）；通过QTL共定位分析发现，海岛棉GbMYB5_A12的等位基因型与纤维长度（FL）、纤维强度（FS）和衣分（LP）等性状显著正相关，其启动子区的顺式作用元件TFmatrixID_0063 (GATGTTGT)的自然变异可能导致海陆等位基因差异表达；通过酵母单杂及双荧光素酶报告基因实验验证了RAV...
Dihaploid induction in tetraploid durum wheat (Triticum durum L.) using pollen of Imperata cylindrica
2,4-dichlorophenoxyacetic acid (2,4-D) haploid induction pseudoseed formation wide hybridization
2015/12/29
Doubled haploidy breeding protocols have revolutionized the varietal development programmes in bread wheat, however, the protocols have not proved much efficient in durum wheat. Presently, the durum w...
Induction of Tetraploid in Loquat with Amiprofos-methyl and Colchicine
Loquat Induction Colchicine young roots
2009/7/13
This experiment was conducted to artificially induce loquat tetraploids by applying amiprofos-methyl (APM) and colchicine for chromosome doubling agents to diploid loquat shoot apex.

Effect of Colchicine and Oryzalin Treatments on Tetraploid Production of Nucellar Embryos in Meiwa Kumquat (Fortunella crassifolia Swingle)
Colchicine Oryzalin Treatments Tetraploid Production Nucellar Embryos
2009/7/13
In vitro chromosome doubling of nucellar embryos was investigated in Meiwa kumquat (Fortunella crassifolia Swingle). Nucellar embryos were aseptically treated with two antimitotic agents, colchicine a...
Production of Triploids and Breeding Seedless Cultivar ‘Tokushima 3X No.1’ from Tetraploid × Diploid Crosses in Sudachi (Citrus sudachi Shirai)
Tetraploid Diploid Production
2009/7/10
To obtain the seedless sudachi of a triploid, 297 flowers were crossed between tetraploid sudachi and diploid sudachi, and 50 triploids were established in 1992. Flowcytometer was used for selection o...
Development of Tetraploid Chinese Lantern (Physalis alkekengi L.var.franchetii Makino) and its Characteristics
chromosome doubling colchicine polyploid
2009/7/8
In vitro chromosome doubling of Chinese lantern (Physalis alkekengi L. var. franchetii Makino) was studied and characteristics of the obtained tetraploids were clarified. The tetraploids could be obta...

Cuting Frequency Height Hay Yield Chemical Characteristics Diploid Tetraploid Perennial Rye
2009/1/15
This study was carried out under greenhouse conditions from March 1995 to August 1996. The effects of cutting frequency and height on hay yield and quality were investigated. In this research, 2 ploi...
Evaluation of an Exotic Germplasm Population Derived from Multiple Crosses among Gossypium Tetraploid Species
Exotic Germplasm Population Multiple Crosses Gossypium Tetraploid Species
2008/12/10
Broadening the genetic base of upland cotton (Gossypium hirsutum L.) is essential for continuous genetic improvement of yield and fiber quality through breeding. The objectives of this study were to e...
