Nucellar polyembryony is reported in species of

Options

A. Citrus
B. Gossyplum
C. Triticum
D. Brassica

Answer

**Step-by-Step Solution:**

1. **Understanding Polyembryony**: Polyembryony refers to the phenomenon where more than one embryo develops from a single fertilized ovule. This can lead to multiple embryos within a single seed.

2. **Defining Nucellar Polyembryony**: Nucellar polyembryony specifically involves the formation of additional embryos from the nucellus, which is the tissue surrounding the embryo sac in an ovule. This means that the nucellar tissue can give rise to new cells that develop into embryos.

3. **Identifying the Process**: In plants exhibiting nucellar polyembryony, the nucellus can produce cells that develop into embryos, which are genetically identical to the parent plant. These embryos are essentially clones of the parent.

4. **Considering the Options**: The question provides four options: Citrus, Gossypium, Triticum, and Brassica. We need to identify which of these species is known for nucellar polyembryony.

5. **Researching the Species**: Among the options, Citrus species are well-documented for exhibiting nucellar polyembryony. This characteristic is common in many varieties of citrus fruits.

6. **Conclusion**: Based on the understanding of nucellar polyembryony and the identification of the species, the correct answer to the question is **Citrus**.

**Final Answer**: Citrus
