Kenaf male sterility breeding gave a new method for the use of kenaf heterosis.

红麻不育系的选育为红麻杂种优势的利用提供了新的途径。

So,the genetic distance could be used for the choice ofparents and for the heterosis prediction in cross breeding of Liriodendron.

因此，花粉品质、杂交亲和力和一般配合力应作为亲本选配的重要依据；基于RAPD标记的亲本间遗传距离与子代1年生苗高和地径生长量均表现为二次曲线相关，复相关系数分别为0.8235和0.5090，达极显著(H，P＜0.01)和显著(GLD，P＜0.05)程度，说明利用亲本间遗传距离进行鹅掌楸亲本选配和杂种优势预测是可行的。

This kind of new virus is caused by recombination between ACMV and EACMV, and there could be a lot of types of recombinant hybrid virus; The cassava mosaic disease before the epidemic was caused by isolates of ACMV.

杂种病毒可能也存在多种类型，这是二个已知的植物病毒基因组重组产生新病毒的首次报道。同时表明乌干达严重木薯花叶病非流行区的木薯花叶病为ACMV引起。

Prom the differences among these hybrids, the basic genetic parameters of quatitative characters were estimated for the two parent's population apart.

优良自交系亚总体各性状的遗传方差则普遍减小，说明其遗传基础更为狭窄。所以，为了不断地育出更好的自交系间杂种，迫切需要补充新的基因源。

Allopolyploidy A type of polyploidy involving the combination of chromosomes from two or more different species.

异源多倍体：两种或两个以上的不相同的物种杂交，杂种经染色体加倍形成的多倍体类型。

The 'Clash brought out some crazy bastards, that's for sure, like these guys, Nick Wood and Robbie Whitcomb, all the way from Santee.

冲突带来了一些疯狂的杂种，这是肯定的，像这些家伙，尼克木材和罗比Whitcomb ），所有的方式从

This paper summarizes genetic basis of hybrid sterility.

在前人研究的基础上，从遗传分化和基因控制的角度综述了籼粳杂种不育现象的遗传基础。

The drought resistance of Chinese Wild Vitis species was studied by shape index, relative water content, and relative plasma permeability under the conditions of drought stress, and evaluated by subordinative function.

本研究以中国葡萄属野生种8个种11个株系，欧洲葡萄2个品种，河岸葡萄及燕山—1×河岸葡萄107株F_1代杂种共122份材料为试材，调查了盆栽干旱胁迫条件下叶片的形态变化指标，测定了相对含水量和细胞膜相对透性两项指标；以隶属函数法为手段处理这三项指标，对供试的葡萄属植物的抗旱性进行了综合评价。

Both yield and quality of common maize grains are improved by crossing high oil maize as male parent and common maize as female parent due to maize heterosis and xenia.

本文利用高油玉米的花粉直感效应及与普通玉米杂交的杂种优势效应，通过高油玉米与普通玉米杂交改善普通玉米的产量和品质。

Based on the obvious xenia effects of high oil and heterosis, a technique called TEU(three-effect-utilization) was developed to pyramid the cytoplasm male sterile effect, heterosis and xenia of oil content into a production system, which has patented in China.

从20世纪20年代开始，玉米杂种优势利用经历了综合种、双交种、三交种、单交种阶段，每一次利用方式的改变都使玉米生产的水平得到了很大的提高。
