Dry Edible Bean White Mold MAGIC Population (original) (raw)

2021

Abstract

A dry edible bean MAGIC population was generated to map genes for resistance to white mold and to produce inbred lines with improved white mold (WM) resistance combined with good agronomic performance for primarily the pinto bean market class. Eight founding parents were crossed to develop a modified MAGIC population. PT7-2 was intermated with Powderhorn (cross A). ID14-4 was intermated with CO16079 (cross B). La Paz was intermated with Lariat (cross C). USPT-WM_12 was intermated with El Dorado (cross D). Subsequently, F1 plants of each initial cross were intermated using a one-way funnel, F1 from cross A was mated with F1 from cross B and F1 from cross C was mated with F1 from cross D meaning that not every possible cross combination was conducted. The next cycle consisted of intermating F1 from the AxB cross with F1 from the CxD cross. For each cycle reciprocal crosses were conducted to offset potential maternal effects and maternal inheritance. After the final crosses, the F1 wer...
