Pure lines

शुद्ध रेखाएँ (Pure Lines)

This Class 10 Agriculture topic introduces pure lines in the context of Seed Production and Nursery Management. Students learn that a pure line is the uniform progeny of a single, genetically homozygous plant, usually maintained through repeated self-pollination. The topic explains how selection, isolation, careful multiplication, and true-to-type nursery practices help preserve varietal identity and desirable traits. It also builds an understanding of genetic uniformity, seed purity, and the importance of maintaining healthy planting material during seed production.
