Dee-Gee-Woo-Gen is the source of dwarfing gene in
A. Rice
B. Bajra
C. Peanut
D. Wheat
Answer: Option A
Solution(By Examveda Team)
Dee-Gee-Woo-Gen is the source of dwarfing gene in Rice.Analysis of the genetic lineage of the majority of the cultivated rice varieties in tropical Asia reveals that sd1 from DGWG (Dee-Gee-Woo-Gen) is the major source of dwarfing gene.
The high amount of genetic homogeneity renders rice plants vulnerable to the epidemic of diseases and insect pests. The phenotype of sd-1 is consistent with dwarfism that results from a deficiency in gibberellin (GA) plant growth hormones.
