Plant Breeding and Genetics MCQ

Plant Breeding and Genetics MCQ or Genetics and Plant Breeding Multiple Choice Questions (बहुविकल्पीय प्रश्न) are MCQ Objectives asked in different agricultural competition exams.

Apart from an agricultural entrance exam, these questions are also asked in others competition exams too such as exams related with agro-forestry, banking, PSC etc.

These questions are also included in general knowledge, which is also a part of different important exams as a subject.

Know About Plant Breeding

Importance of The Subject

This is one of the very important subject in B. Sc. Agriculture and M. Sc. Agriculture.

In B. Sc. Agriculture, students from the following subjects are eligible after 12th,

  • First students of agriculture.
  • Second students of science.
  • Third students of mathematics.

Generally, it is easy for the students of science but for the students of agriculture and mathematics most of the topics from this subject are not easy as compared to science-students.

Almost all important entrance exams related with agriculture include topics from plant breeding and genetics in syllabus.

Scoring good marks from this subject help in cracking the exam with very good rank.

Although, students have to give importance to subjects like agronomy, horticulture, entomology, soil science etc.

Topics of The Posts

  • Fundamentals of Genetics and Plant Breeding.
  • Structure and Function of Cell.
  • Mitosis.
  • Meiosis.
  • Mandellian Genetics.
  • Plant Biotechnology.
  • Tissue Culture.
  • Structure and Functions of Carbohydrates, Proteins, Enzymes, Vitamins.
  • DNA.
  • RNA.………..and others.

Exams Related With The Subject
