概括
开发新的米线,以小的,黑色的谷物和多个谷物每spikelet可以增加素的产量. 这些改进的米品种为消费者和育种者提供了健康益处和更高的生产率.
科学领域:
- 农业科学 农业科学
- 植物育种 植物育种
- 遗传学 遗传学 是一个
背景情况:
- 富含安东素的米饭因其健康益处而备受追捧,但提高产量往往与更高的安东素含量无关.
- 安西安酸位于花皮和种子外中,使得谷物表面积对含量至关重要.
研究的目的:
- 通过增强小,黑色和多谷物特征,开发增加每面积安托素产量的水生产线.
- 为了确定优越的重组杂交品种 (RILs) 对于安托素的生产和产量.
主要方法:
- 六个RIL是从Niaw Dam Chaw Mai Pai 49 (NDCMP49) 和Khao Nok (LLR059) 之间的交叉中培育出来的.
- 从F1到F4的世代中使用了血统选择来选择颗粒的颜色,大小和每颗颗粒的颗粒数量.
- 实地试验是在两年内在四个地点进行的随机完全区块设计 (RCBD) 中进行的.
主要成果:
- 环境条件的显著差异影响了大米的生产力和产量组成部分.
- 三个RIL (13-1,374-1,903-3) 的产量表现高于母公司NDCMP49,但产量在不同环境中不稳定.
- RILs 374-1和903-3表现出高产量和中度的抗素含量,具有可取的特征,如黑色颗粒和每个尖端颗粒的三个颗粒.
结论:
- 为获得高产量和酸盐含量进行选择性育种,需要考虑特定的环境条件.
- RILs 374-1和903-3有望与NDCMP49进行逆交,以增强稳定,高素积累.
- 这些开发的RIL为未来的米育种计划提供了宝贵的资源,专注于富含安素的品种.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...

21.8K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
