- 识别开发新种木瓜品种的潜力,具有多样化的水果图案.
- 评估选择水果形状对其他水果质量参数的影响.
主要方法:
- 评估了97个同血统的番茄品种,这些品种是由JS-12和Sekati基因型之间的交叉产生的.
- 应用统计分析来测量水果质量特征的遗传变异性.
- 对水果形状选择进行形态解剖学特征评估.
主要成果:
- 在评估的木瓜品种中,在水果质量特征中观察到显著的遗传变异性.
- 水果形状特征对整体遗传变异性贡献最大.
- 多种多样的 F5 番茄系列显示出在 Formosa, Intermediate 和 Solo 模式下进行商业水果生产的潜力.

Dihybrid Crosses
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...
