Early selection of potato clones with the H1 resistance gene – the relation of nematode resistance to quality characteristics
breeding Globodera rostochiensis marker-assisted selection MAS Solanum tuberosum
2014/12/1
Breeding a new potato cultivar is a long-term process ending with a few elite individuals from initially large populations. Screening for resistance in the seedling and first clonal generations is a c...
Mass Selection and Grain Yield of Improved Population in Pearl Millet (Pennisetum typhoideum Rich.)
Genetic gain Genotype-environment interaction Grain yield Improved population Mass selection
2009/7/24
Mass selections for germination at low temperature, heavy grain weight and early heading were applied in a pearl millet population. Selection for short plant height was also applied by the ear-to-row ...
Genetic Gains and Genetic Correlations of Yield-related Traits in Pearl Millet after Two Cycles of Recurrent Selection
Genetic correlation Genetic gain Grain yield Heritability Mass selection Pearl mille
2009/7/16
Two cycles of recurrent selection were applied on a pearl millet (Pennisetum typhoideum Rich.) population sown in late summer. The procedure increased not only the selected characters, grain weight a...
Evaluation of the Efficiency of Selection of Pearl Millet in Japan and Indonesia
Genetic correlation Heritability Shortening of breeding cycle Genetic gain Adaptability
2009/7/7
The efficiency of selection for early matuyring, short culm and long panicle in a pearl millet population ICMV89074 was evaluated. It was possible to evaluate the efficiency of selection in a year b...
Enhancing the breeding value of genotypes through genetic selection in cotton（Gossypium hirsutum L.）
G. hirsutum genetic parameters F2 and F3 generation breeding value yield components
2009/3/12
Selection for improvement of desirable traits will be successful only when it is performed based on reliable genetic parameters. An experiment was conducted by segregating populations of eight intra-...
Participatory variety selection and characterization of Sorghum（Sorghum bicolor（L.）Moench）elite accessions from Malawian gene pool using farmer and breeder knowledge
Participatory variety selection Sorghum bicolor Malawi agrobiodiversity
2009/3/4
Participatory approaches for variety selection, breeding, ex-situ and in-situ conservation of neglected crops in Malawi was initiated in 1998. The specific objective of the present study was to se...
Assessment of selection techniques in genotype X environment interaction in cowpea Vigna unguiculata（L.）walp
Genotype X environment interaction selection techniques cowpea Vigna unguiculata
2009/3/3
Ten genotypes of cowpea were grown in four environments comprising the early and late seasons of Ogbomoso and Abeokuta locations in 2005 and 2006. Joint linear regression analysis indicated the pres...

Pinto bean (Phaseolus vulgaris var. Pinto) genotype selection Turkey
2009/1/9
Species belonging to the family Leguminosae are widely grown in Turkey. Pinto bean (Phaseolus vulgaris L. var. Pinto) is a traditional crop in Turkey and farmers grow local varieties that they select...
Comparison of Bulk F2 Performance Testing and Pedigree Selection in Thirty Pima Cotton Populations
Bulk F2 Performance Testing Pedigree Selection Thirty Pima Cotton Populations
2008/12/10
The objective of early generation testing is to increase breeding efficiency through early identification of superior heterogeneous populations. Bulk F2 testing has gained adherents among the cotton b...
Cotton breeders routinely discard progeny rows that visually appear low yielding. Such a process is essential, because it would be highly inefficient to continue to work with progeny that have no comm...
小麦异交群体连续歧化选择的RAPD分析RAPD Marker Analysis of Continuous Divergent Selection in Cross-Bred Population of Wheat (Triticum aestivum L.)
小麦异交群体 数量性状 遗传距离
2007/12/30
摘要利用太谷核不育基因构建的遗传变异丰富的基础群体DNS2，进行了连续5轮歧化选择。本论文从不同的世代中，选择了10个子群体进行RAPD分析。采用7个引物扩增出116个位点，从基因频率和表型带两个角度的分析都表明，群体具有丰富的遗传变异。整个群体总的多态位点百分率达88.79，总杂合度为0.3143。子群体内（间）遗传距离的结果显示：子群体内的遗传差异小于子群体间的遗传差异；各选择子群体与未选群体...
