Inbred lines in plants

Webcrossing two unrelated, homozygous inbred lines. Traditionally, the maize plants’ cross-breeding nature required recurrent self-pollinations for 6–10 generations, i.e., 3–5 years when two seasons per year can be accomplished, to obtain sufficiently homozygous inbred lines [13]. Inbred lines are genotypes that are developed to be used as WebSep 25, 2024 · The production of maize DH lines involves the following four steps: (1) induction of haploids; (2) identification of haploids at seed or seedling stage; (3) chromosome doubling in the haploids; and (4) selfing the fertile doubled haploid plants to produce seed for DH lines.
