- Published on 02 Jun 16

a. Groundnut
b. Beetlenut
c. Peanut
d. Both a and c
e. All the above

ANSWER: Both a and c
 
A scientific breakthrough of the DNA sequencing of the groundnut promises development of improved varieties with enhanced traits such as increased pod and oil yield, drought and heat tolerance and greater disease resistance.
  • Close to 51 scientists from 9 institutes in China, India, US and Australia including ICRISAT have decoded the complete DNA sequencing of a groundnut ancestor called diploid A-genome (Arachis duranensis)
  • Other significant traits will help in developing aflatoxin-free, nutrition-rich and allergen varieties providing insights into geocarpy which is a unique reproductive process of groundnut, oil biosynthesis and allergens.
  • Study has provided the complete genome sequence to assist plant breeders across the globe come up with more productive and resilient groundnut varieties in a faster way.
  • The study presented the groundnut lineage was affected by 3 sets of chromosomes since the origin of flowering plants or eudicots.
