Advantage of pureline selection

  1. The purelines are extremely uniform since all the plants in the variety will have the same genotype.
  2. Attractive and liked by the farmers and consumers.
  3. Purelines are stable and long test for many years.
  4. Due to its extreme uniformity the variety can be easily identified in seed certification programmes.

 

Limitations or disadvantages of pureline selection

  1. New genotypes are not created by pureline selection
  2. Improvement is limited to the isolation of the best genotype present in population. No more improvement is possible after isolation of the best available genotype in the population.
  3. Selection of purelines require great skill and familiarity with the crop.
  4. Difficult to detect small differences that exist between cultures
  5. The breeder has to devote more time
