More than 1000 genotypes are required to derive robust relationships between yield, yield stability and physiological parameters: a computational study on wheat crop
Theoretical and Applied Genetics - Tập 136 - Trang 1-15 - 2023
Tien-Cheng Wang, Pierre Casadebaig, Tsu-Wei Chen
Using in silico experiment in crop model, we identified different physiological regulations of yield and yield stability, as well as quantify the genotype and environment numbers required for analysing yield stability convincingly. Identifying target traits for breeding stable and high-yielded cultivars simultaneously is difficult due to limited knowledge of physiological mechanisms behind yield s...... hiện toàn bộ
The use of pollen irradiation in barley breeding
Theoretical and Applied Genetics - Tập 65 - Trang 73-76 - 1983
W. Powell, P. D. S. Caligari, A. M. Hayter
Second generation progenies (M2) derived from crosses using barley pollen irradiated at 500, 1,000 1,500 and 2,000 rads increasingly resembled the maternal parent. ‘Golden Promise’, but contained some characteristics derived from the paternal parent, ‘Magnum’.
Influence of Zinnia angustifolia HBK genotype on embryonic and vegetative development of Z. angustifolia x Z. elegans Jacq. interspecific hybrids
Theoretical and Applied Genetics - Tập 73 - Trang 716-723 - 1987
T. H. Boyle, D. P. Stimart, G. R. Bauchan
Interspecific crosses between Zinnia angustifolia clones (maternal parents) and Z. elegans lines (paternal parents) were performed to investigate postzygotic barriers among Z. angustifolia X Z. elegans hybrids and to determine influence of parental genotype on embryonic and vegetative development of interspecific hybrids. Variation in percentage of emerged seedlings (PES) and percentage of morphol...... hiện toàn bộ
AFLP analysis of genetic relationships among papaya and its wild relatives (Caricaceae) from Ecuador
Theoretical and Applied Genetics - Tập 105 - Trang 289-297 - 2002
B. Van Droogenbroeck, P. Breyne, P. Goetghebeur, E. Romeijn-Peeters, T. Kyndt, G. Gheysen
The AFLP technique was used to assess the genetic relationships among the cultivated papaya (Carica papaya L.) and related species native to Ecuador. Genetic distances based on AFLP data were estimated for 95 accessions belonging to three genera including C. papaya, at least eight Vasconcella species and two Jacaratia species. Cluster analysis using different methods and principal co-ordinate anal...... hiện toàn bộ
Telo aneuploids in pearl millet
Theoretical and Applied Genetics - Tập 60 - Trang 381-382 - 1981
J. V. Pantulu, G. J. Narasimha Rao
Nomenclature and chromosome constitution for twenty different aneuploids with telocentrics in Pennisetum typhoides are presented.
Identification of a suppressor for the wheat stripe rust resistance gene Yr81 in Chinese wheat landrace Dahongpao
Theoretical and Applied Genetics - Tập 136 - Trang 1-13 - 2023
Huiling Jin, Haipeng Zhang, Xuyang Zhao, Li Long, Fangnian Guan, Yunpeng Wang, Linyu Huang, Xiaoyue Zhang, Yuqi Wang, Hao Li, Wei Li, Zhien Pu, Yazhou Zhang, Qiang Xu, Qiantao Jiang, Yuming Wei, Jian Ma, Pengfei Qi, Mei Deng, Houyang Kang, Youliang Zheng, Guoyue Chen, Yunfeng Jiang
Combined with BSE-Seq analysis and multiple genetic populations, three genes involved in stripe rust resistance were identified in Chinese wheat landrace Dahongpao, including a novel suppressor on 2BS. Dahongpao (DHP), a landrace of hexaploid wheat in China, exhibits a high degree of stripe rust resistance in the field for many years. In this study, bulked segregant analysis coupled with exome cap...... hiện toàn bộ

Origin of an alien disomic addition with an aberrant homologue of chromosome-10 of tomato and its meiotic behaviour in a potato background revealed through GISH
Theoretical and Applied Genetics - Tập 98 - Trang 1263-1271 - 1999
F. Garriga-Calderé, D. J. Huigen, E. Jacobsen, M. S. Ramanna
While characterising potato (Solanum tuberosum, 2n=4x=48) clones with alien tomato (Lycopersicon esculentum) chromosome additions, a single addition for chromosome-10 of tomato was identified through restriction fragment length polymorphism (RFLP) analysis. This plant, 2101–1, was a BC2 derivative from a cross between a potato (+) tomato fusion hybrid backcrossed to potato. Cytological analysis o...... hiện toàn bộ
Genomic prediction of hybrid performance in maize with models incorporating dominance and population specific marker effects
Theoretical and Applied Genetics - Tập 125 Số 6 - Trang 1181-1194 - 2012

Genetics of resistance to Puccinia graminis tritici in ‘Chris’ and ‘W3746’ wheats
Theoretical and Applied Genetics - Tập 73 - Trang 846-855 - 1987
R. P. Singh, R. A. McIntosh
‘Chris’ wheat possessed genes Sr5, Sr7a, Sr8a, Sr9g and Sr12. ‘W3746’, derived from the cross ‘Chris’/‘Baart’, possessed Sr7a and Sr12. The response conferred by Sr7a was influenced by the genetic background. Although Sr7a or Sr12 alone conferred no observable resistance upon adult plants, the adult resistances of ‘Chris’ and ‘W3746’ to predominant pathotypes appeared to be associated with the int...... hiện toàn bộ
