查询词典 parent population

While doing the RFLP tagging of giant embryogene,the genome changebetween mutants and its original parent,the relationship between RFLP andheteroses in indica,japonica and intermediate rice,the performance of multipleand null allelism in rice varieties,the utilization of null allelic RFLP probes inidentifying indica and japonica rice specifically,the distribution of the nullallelic RFLP probe RG684 in rice cultivars,and the segregations of RFLPmakers in indica/japonica F2 population were also studied.

本实验从经典遗传、分子遗传、育种潜力评估、育种新品系选育等领域，对巨大胚、甜胚乳、暗胚乳三种新型突变体进行了全面系统研究。在对巨大胚进行分子定位过程中，对涉及到的突变体与原始亲本基因组变化，籼、粳、中间型材料的RFLP多态性与杂种优势之间关系，水稻品种的复等位、零等位表现，鉴定籼、粳特异性的零等位RFLP标记，零等位标记RG684在稻种中分布，RFLP标记在籼粳交F2群体中分离等遗传现象也一并进行了分析。

The maps are not,however,desirable and entire because all of the markers on the maps come from the no recurrent parent.The consequence is that number of the markers used for map in backcross population is never more than half in intercross population.

但是，用回交群体作图所得的图谱是不完整的，因为图谱上所有的标记都是非轮回亲本提供的，因此标记数不会超过杂交F2群体的一半。

Another big factor of poverty is the ever-growing single parent's population.

贫困的另一个重要因素就是日益增长的单亲家庭总数。

Objective To detect and evaluate the genetic diversity and differences between SPF golden hamster population and its parent conventional population, and provide useful information and references for quality control of SPF golden hamsters.

目的 检测和评估金黄地鼠封闭群SPF化后的遗传学变化，为SPF金黄地鼠遗传质量的控制提供技术资料。

Analyzed the hereditary variation distribution of amylose content in DH population, estimated hereditary capacity and rate over parent in DH population by the model and formul which were presented by Choo and Reibergs, and examined the number of gene pairs and the pattern of gene interaction which controlled these characters.

应用Choo和Reibergs提出的模型及公式，分析了这6个DH群体AC的分布、测算了遗传力、超亲率，检测了AC的基因对数及基因互作方式。

Methods Microsatellite markers of mice and rat were adopted to develop markers and methods suitable for genetic monitoring for SPF golden hamster population and its parent conventional population from Chengdu Institute of Biological Products by fluorescence-based semi-automated genotyping method. Genetic diversity and differences of the 2 golden hamster populations were analyzed based on the result of microsatellite alleles.

应用小鼠和大鼠的微卫星标记筛选适于金黄地鼠遗传检测的微卫星标记，并结合微卫星荧光标记－半自动基因分型技术，对成都生物制品研究所的SPF级金黄地鼠及其来源的普通级金黄地鼠进行遗传检测，计算其群体遗传学参数。

Using an inbred line of Sichuan Yellow as the recurrent parent and Purple-leaf Mustard as the donor parent, one BC_5F_2 segregating population was developed and used for mapping the gene controlling seed coat color.

以四川黄籽为轮回亲本，紫叶芥为供体亲本培育的BC_5F_2分离群体为种皮颜色基因的定位群体，找到了2个与棕色种皮基因连锁的SCAR标记SZ1_(-331)和SCAR57_(-383)。

The fact that the pink plants were predominant among the population of RP1 cross progeny hints that the pink had the strong descendiblity, Whereas another fact that the plants with the color of another parent were predominant among the population of R01 cross progeny indicates that the nacarat/saffron plant had the low descendiblity. The above results suggest that it is better to choose the pink plants with the target color flower of breeding as a parents when arranging the cross combination. Many novel flowers with singular value of view and admire can be bred by the different cross combination since the wide segregation chromatogram is not confined to the parents'.

以RPl及R01作母本或父本，分别与不同花色杂交，F1代发生了明显的花色分离，RP1的杂交后代均以粉色占优势，表明粉色的遗传力较强，R01的杂交后代均以其它亲本占优势，表明桔黄/桔红的遗传力较弱，因此在选配组合时，最好选择具有育种目标的粉色个体作为亲本；另外由于分离谱较广，且分离的色谱范围并不完全限于双亲之间，可根据不同的杂交配组，培育出具极高观赏价值的稀有花色。

Fifty-five lines with different Wx genes from the DH population of Yangmai 10/Waxy C, and 12 waxy wheat varieties derived from the crosses or backcrosses of Yangmai 9 as no-waxy parent or recurrent parent with different waxy wheat varieties were used to study the effects of Wx genes on percentage of vitreous kernel. The grain protein content of 12 waxy wheat varieties with floury endosperm from different crosses was also tested.
