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. Haploid induction WebThe production of a hybrid corn variety involves three steps: (1) the selection of superior plants; (2) selfing for several generations to produce a series of inbred lines, which …
What is inbred line in plant breeding? - Studybuff
WebInbred strains (also called inbred lines, or rarely for animals linear animals) are individuals of a particular species which are nearly identical to each other in genotype due to long inbreeding. What is RIL population? A recombinant inbred line (RIL) population is developed using single seed descent from the F2generation. WebOct 24, 2024 · Production of pure lines is an important step in biological studies and breeding of many crop plants. The major types of pure lines for biological studies and breeding include doubled haploid (DH) lines, recombinant inbred lines (RILs), and near isogenic lines (NILs). DH lines can be produced throug … grace hopper short bio
Accelerated Generation of Selfed Pure Line Plants for Gene ...
WebInbreeding generally leads to loss in yield; the inbred lines yield much less than the open pollinated varieties from which they are derived. Heterosis is generally expressed as an increase in yield of the hybrid. Commercially this phenomenon is of great importance as an objective of plant breeding. 4. WebMar 27, 2024 · Sunflower is a hybrid crop, and CWRs were used to develop cytoplasmic male sterile “female” lines and branching, fertility-restoring “male” lines for hybrid production. The male-restorer lines (PSC8, OQP8, and RHA438) generally had more introgressions than the female-maintainer lines (HA412, XRQ, IR, HA89, LR1, and HA300) ( SI Appendix, Fig. S16 ). WebNov 6, 2024 · Adult healthy whiteflies, provided with 24 h acquisition on diseased tomato plants, were released on 28 days old healthy tomato inbred lines, and susceptible control in an insect proof cage. To ensure the 100% infection, plants were inoculated with 10–25 whiteflies per plant and maintained at 26–32 °C. grace horgan
