In this study, 259 F(subscript 2:3) lines, developed from a cross between a dent corn inbred Dan232 and a popcorn inbred N04, were grown in a replicated experiment and evaluated for three popping characteristics. Of 613 simple sequence repeat primer pairs screened, 183 pairs were selected to construct a genetic linkage map 1762.2cM long with an average interval of 9.63cM.

本研究以普通玉米自交系丹232和爆裂玉米自交系N04杂交构建的259个F(下标 2：3)家系为定位群体，采用完全随机区组设计在郑州夏播条件下测定了3个膨爆特性指标。

Two hundred and fifty-nine F2:3 and 220 BC2S1 families,derived from the same cross between Dan232,a dent corn inbred and NO4, a popcorn inbred, were evaluated for four developmental stages, tassel emergence, male anthesis, silk emergence and days from male anthesis to silk emergence.

以普通玉米自交系丹232和爆裂玉米自交系N04为亲本构建259个F2.3和220个Bc2S1家系群体，利用SSR标记构建分子标记遗传图谱，利用复合区间作图方法对4个生育期性状进行QTL定位和效应分析。

The members with Leber hereditary opˉtic neuropathy have a point mutation in mtDNA and the mutation at np11778is one of mechanisms inducing this disease.PCR technique provides a useful diagnostic aid for LHON.

该LHON家系成员存在线粒体DNA点突变，mtDNA的ND4亚单位第11778核苷酸突变是本病的发病机制之一，PCR-限制性核酸内切酶酶谱分析技术为LHON的诊断提供了依据。

The mixed solution is at the proportion of 7 Methanol to 1 Dichloromethane .

其中21、34、56、77这4个家系在S_1和S_2中的平均遗传增益都是最高，最值得关注。

Taking DOPA as substrate, polyphenol oxidase activity of the F_2 and F_(2∶3) family groups derived from across between Yangmai 158 and Huaimai 18 were measured with the method of whole-meal filtering.

为了了解早代PPO活性的分布情况，以多巴(L-DOPA/MOPS)为底物，采用全麦粉过滤法测定了小麦组合(扬麦158×淮麦18)早代(F2和F2∶3家系群体)的PPO活性。

The ancestry of the piano can be traced to the early keyboard instruments of the fifteenth and sixteenth centuries -- the spinet, the dulcimer, and

钢琴的家系可以追溯至 15 至 16 世纪早期的键盘乐器，包括小型拨弦琴、洋琴和维金娜琴。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
