Line breeding in plants. Breeding lines refer to a small selected number of advanced plant varieties that are developed through a breeding process, which involves hybridisation and line fixation, ultimately leading to the selection of the most promising genetic material for further testing and evaluation. Line breeding is the process of creating a population of similar or almost identical plants, known as a “line”. Line breeding is used for plant varieties that usually breed through self-pollination (e. barley, wheat, oats and peas). The details of each step are described below. , 2017). The process of cultivar development for pure line varieties involves choosing parents, creating progeny and materials for testing, and evaluating and selecting desirable lines. Such plants are fertilized by their own pollen, even before they leave the flowering stage. LINE BREEDING commonly involves the creation of a population of similar or virtually identical plants which is referred to as a “line”. Parental line selection in plant breeding usually has two differing goals: (i) identify suitable parents for commercial hybrid varieties and (ii) identify suitable parents to develop inbred lines for subsequent breeding cycles (Gaynor et al. Mass Selection and Pure Line Selection are two important methods in plant breeding, each with its own strengths and limitations. g. . These plants may be selected for common characteristics, and can be inbred, partially closed, or minimally inbred. Mass Selection offers simplicity and the preservation of genetic diversity, while Pure Line Selection provides rapid fixation of desirable traits and genetic uniformity. These plants may have been selected for common desired characteristics (such as a purple line or a tall, spidery purple line). cuy opqdf iffj uopvj awoci eicu nikzf ttidmo cnfwc bnp
