HYV种子和传统种子之间的差异

Key Difference – HYV Seeds vs Traditional Seeds

品种改善是育种者的一种常见实践，目的是开发具有改善特征的高产作物品种，例如高晶粒质量，早期成熟，活力幼苗，更好地采用环境，压力耐受性等。品种改善主要集中在高产上，通过可持续农业满足人们需求的品种。高产种子（HYV）是由遗传增强的高产量品种产生的种子。传统种子是长期生长的种子，而无需修改或增强植物的特征。HYV种子和传统种子之间的关键区别在于HYV种子可产生较高的屈服品种，具有更好的质量和环境采用，而传统种子则产生较低的屈服品种，质量正常，环境耐受性较小。

什么是HYV种子?

具有理想特征的改善农作物品种是农业的必要条件，以满足人口的粮食需求并面临环境挑战。高产品种（HYV）是育种者开发的新型品种，可通过改进的质量测量获得经济利益。它们也被称为现代品种。选择并繁殖为现代品种的作物物种的有利的突出特征。因此，HYV被称为遗传增强的品种。

Development of HYVs initiated during the mid-1960s in Mexico with the efforts of Prof. Norman Borlaug and his associates. The first HYVs were wheat varieties which were early maturing, disease resistant and highly productive. There are several HYVs popular in developing countries such aswheat, rice,玉米等等。获得HYV品种获得HYV种子是一个昂贵的过程，与相比traditional farming。生产所需的HYV种子可能需要连续种植。

什么是传统种子？

传统品种的种植的作物品种for a long time period by the farmers. They are not artificially modified. These varieties have good as well as bad characteristics. The cultivation of traditional varieties is becoming less practiced since the high yield varieties are popular among the farmers. Traditional seeds are the products of traditional varieties. They give rise to low or normal quality plants with less tolerance to the environmental challenges and poor yield. Traditional varieties show prominent vegetative growth than high yielding varieties. However, they show poor yield characteristics. Though traditional seeds do not produce high quality plants, they are not subjected to artificial genetic modification. Therefore, it is believed that the use of traditional seeds is safe and has higher health benefits.

HYV种子和传统种子有什么区别？

HYV种子与传统种子
HYV种子是更好的种子。	传统种子是正常的种子。
遗传改善
这些是遗传改善的种子。	Genetic make up of the seed is not modified of enhanced.
Need for Labor of Production
This is labor intensive.	Comparatively, not labor intensive.
输入
HYV种子需要高水平的化肥和良好的供水	Requirement for chemicals and water are at the normal recommended levels.
害虫和疾病
这些不太容易发生害虫和疾病。	These are more prone to pests and diseases.
洪水和干旱
HYV种子对洪水和干旱有抵抗力。	Traditional seeds are susceptible to flood and drought.
屈服
These give a higher yield per unit area.	These give a low yield per unit area.
植物
Mother plants are dwarf and stiff strawed.	植物are not artificially dwarf and stiff strawed
资本和技术的需求
The successful cultivation of HYV seeds requires more capital and modern farming tools such as tractors etc.	Modern tools and technologies are not necessary for traditional farming. Capital investment also less in traditional farming.

Summary – HYV Seeds vs Traditional Seeds

HYV种子是遗传增强的种子，以提高产量。它们导致具有良好特征的高质量植物。传统种子是从长时间生长的植物产生的天然种子，而没有修改特征。这是HYV种子和传统种子之间的区别。
