Backcross progeny CSSLs Leaf Panicle Plant type QTL Rice (Oryza sativa L.)
2009/7/23
Thirty-nine chromosome segment substitution lines (CSSLs) population derived from a Koshihikari/Kasalath cross was used for quantitative trait locus (QTL) analysis of plant type in rice (Oryza sativa ...
The QTL Analysis of RuBisCO in Flag Leaves and Non-Structural Carbohydrates in Leaf Sheaths of Rice Using Chromosome Segment Substitution Lines and Backcross Progeny F2 Populations
Backcross progeny Chromosome segment substitution lines (CSSLs) Leaf sheath Non-structural carbohydrate (NSC) QTL Rice (Oryza sativa L.) RuBisCO
2009/7/21
In rice (Oryza sativa L.), the maintenance of high photosynthetic rate of flag leaves and the carbon remobilization from leaf sheaths after heading is a critical physiological component affecting the ...
Development of Chromosomal Segment Substitution Lines from a Backcross Recombinant Inbred Population of Interspecific Rice Cross
DNA marker Dongxiang wild rice chromosomal segment substitution line
2009/1/7
A backcross recombinant inbred line population consisting of 202 lines was developed from Xieqingzao B // Xieqingzao B / Dongxiang wild rice. The population was assayed with DNA markers and phenotyped...
Lowering Grain Amylose Content in Backcross Offsprings of indica Rice Variety 057 by Molecular Marker-Assisted Selection
molecular marker-assisted selection indica rice amylose content grain quality
2009/1/7
To lower the amylose content (AC) of the indica rice restorer line 057 with high AC, backcrosses were made respectively by using four indica varieties (R367, 91499, Yanhui 559, Hui 527) as low AC don...
Assessment of Day-Neutral Backcross Populations of Cotton Using AFLP Markers
Assessment Day-Neutral Backcross Cotton AFLP Markers
2008/12/10
The cotton (Gossypium hirsutum L.) collection of primitive accessions is underutilized for cotton improvement because they are photoperiodic. Day-neutrality can be achieved by crossing with a day-neut...
甘蓝型油菜Ogura 雄性不育×白菜的回交杂种后代与亲本之间蕾期基因表达差异比较研究*Differences of Gene Expression in Bud Stage of Backcross Hybrid Between Ogura-type Male-Sterile Brassica napus L and B campestris L versus Parents
Ogura雄性不育 白菜 蕾期 基因表达 cDNA-AFLP 远缘杂交 回交
2008/1/10
摘要
以甘蓝型油菜（Brassica napus L， AACC，2n＝38）Ogura细胞质雄性不育材料为母本，以不同白菜（B campestris ssp. chinensis Makino, AA, 2n＝20） 自交系‘新选一号’和‘矮脚黄’为父本进行杂交，获得了杂种F1、BC1、BC2代。利用cDNA-AFLP技术对两种材料的不同回交世代BC1、BC2代与其亲本在蕾期的基因表达进行分析...
