Kinds of hot pepper materials were used for experiment. The correlation amongphysiological and biochemical characteristics, agronomic characters and resistance todisease characters was studied and the genetic relationship of 12 pepper materials wasidentified by using POD isozymes, the content of capsicin was determined by HighPerformance Liquid Chromatography.

本试验以12个辣椒品种或材料为试材，研究了辣椒生理生化特性、农艺性状和抗病性间相关性；应用POD同工酶对12个辣椒材料，进行亲缘关系的鉴定；高效液相色谱法测定辣椒素。

In this study,70 genotypes of Cucurbita moschata collected from different agro-ecological zones of China were analyzed for genetic diversity,based on the morphological and RAPD markers.

本研究利用形态学标记和RAPD分子标记同时对70份来自我国不同地区的中国南瓜种质进行遗传多样性和亲缘关系分析。在所观察的56个有差异的农艺性状中，变异系数从6.60%~262.22%，平均变异系数为37.50%。

According to the basic information such as origin, agricultural characters of different germplasm, 444 representative domestic cultivars, belonging to 13 species or varieties, 7 genus of cucurbitaceae respectively, were selected as experimental materials to identify their resistance to root-knot nematode using the inoculation method of infected soil. Results showed the resistance distribution of different cucurbit crops.

根据不同种质的来源地、农艺性状等背景信息，从国家蔬菜种质资源中期库中选取具代表性的444份主要瓜类作物地方品种，分属葫芦科7个属的13个种或变种，采用病土接种法进行苗期根结线虫抗性鉴定，得出了不同葫芦科作物对南方根结线虫的抗性分布范围。

Heterosis of eight agronomic important characters of F 1 derived from different ecological types in japonica rice and combining ability of their parents were studied by an 8×8 diallel design.

用 8个不同生态类型的粳稻品种配成 8× 8双列杂交，研究 8个重要农艺性状的杂种优势以及亲本的配合力。

Based on F1 diallel crosses involving eight genetically diverse wheat cultivars, inheritance of harvest index and its correlations with agronomic traits were analyzed.

利用8个不同收获指数小麦品种双列杂交的F1及其亲本，探讨小麦收获指数的遗传及其与主要农艺性状的相关。

Is a tetraploid with tetrasomic inheritance and high heterogeneous genetic base, genetic segregation is more complicated than ones with disomic inheritance.

为高度杂合的无性繁殖同源四倍体作物，极其复杂的异质性和四体遗传导致加工品质和重要农艺性状遗传分析和改良困难。

Four varieties and five different groups (25-200 plants ) were used for 3 years in the research, and anemogamy and entomophilous pollination in nature was used as the check,and agronomical character, chromosomes and isoenzymes were studied.

连续3年，选用4个品种，设25～200株5种不同群体，采用人工授粉等5种授粉方法，以自然条件下风、虫自然传粉为对照。从农艺性状调查，染色体观察及同工酶分析方面进行研究。

Thirty four of total 99 QTL showed significant cytonuclear epistatic effects.

这些结果表明，本研究调查的12个农艺性状不同程度地受到核质上位性的影响。

The principle component analysis showed that head rice ratio, amylose content, chalkiness ratio, gelatination consistency and protein content were most quality traits in low amylase content (5-15%), and head rice ratio, amylose content and chalkiness ratio were most quality traits in low amylase content (5-15%). Correlation of amylose content and 8 agronomic traits showed that: if single plant of low amylase was selected, its'agronomic traits would be affected in negative. Tassel time of low amylose content in 3 combinations was early in their tassel time, and it was important time to select it.

通过主成分分析，可以把整精米率、直链淀淀粉含量、垩白米率、胶稠度和蛋白质作为F2代选择低直链淀粉含量(5-15%)单株的主要品质性状，把整精米率、直链淀淀粉含量和垩白米率作为F3代选择低直链淀粉含量(5-15%)单株的主要品质性状，从而提高选择效率。3个组合类型中，选择低直链淀粉含量较低的单株时，其农艺性状会受到负面影响。3个组合类型低直链淀粉含量单株的抽穗日期都是在每个组合的抽穗早期，因此这是选择低直链淀粉含量单株的重点时期。

Scab resistance, agronomic traits and their improvement effects of 4 wheat gene pools were studied with different recurrent selection populations under single-floret inoculation with Gibberella zeae.

用长期库LP和抗源库RP的C_1、C_4，近期库GPⅠ和CPⅡ的C_0、C_3轮选群体，在赤霉病单花接种条件下，对其3轮选择前后的抗赤霉病性和10个农艺性状的表现及具改良效果进行了分析。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
