概括

在非传统平原地区,由于长期生长阶段和低温,常豆产量较低. 为了提高这些地区普通豆 (Phaseolus vulgaris) 产量,低温耐受性的育种至关重要.

科学领域:

农业科学农业科学
植物育种植物育种
环境科学环境科学

背景情况:

常见豆 (Phaseolus vulgaris) 传统上是在印度山区种植的,努力将种植扩展到非传统平原.
了解基因型与环境的相互作用是适应新地区作物的关键.

研究的目的:

在对比的环境中 (山丘与平原) 评估异国情调的常见豆线对特定地点的反应.
评估生态现象学动态,基因型与环境的相互作用,并确定非传统地区的优势线.
确定环境因素对普通豆产量和生长阶段的影响.

主要方法:

现场评估29种异国情调的普通豆线和3种使用增强设计的局部检查.
在Shimla (北部山区,NHZ) 和Kanpur (北部平原区,NPZ) 进行的试验持续了两年 (2020-2022).
分析包括多变量分析和线性混合模型来评估产量,表态和环境影响.

主要成果:

在NPZ的作物产量比NHZ低33-41%.
植物生长和繁殖阶段在NPZ中延长,在开花和繁殖期间的最低温度 (TMIN F,TMIN R) 和湿度与产量积极相关.
延长作物持续时间和较低的最低温度对产量产生了负面影响,多变量和线性混合模型分析证实了这一点.

结论:

低温和平原长期生长显著降低了普通豆的产量.
为了在非传统平原地区成功种植常见豆,为低温耐受性进行育种至关重要.
异国情调的线条EC931971,EC931452和ARUN显示出作为提高作物的高产,稳定的遗传资源的潜力.

关键词:

这种植物是Phaseolus vulgaris.在AMMI分析中,AMMI分析越来越多的程度天天.多变量线性回归的多变量线性回归现象学现象学是指现象学.收益率收益率是指收益率.

Light Acquisition

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
