Solution(By Examveda Team)

The concept of a multiline cultivar was developed by Jensen (1952).
The concept of the multiline as an approach to the long-term control of diseases in self-pollinated crops was first presented by Jensen, 1952 in oats and next by Borlaug and Gibler (1953) in wheat.
The multiline approach is concerned with the management of resistance genes that condition vertical resistance. Multiline crop cultivars are phenotypically similar (height, grain type) but genetically different against insect pests and diseases.
