plants homozygous screen pizzeria-finaleligure.it

Apr 30 2013 · The quickest possible route to a homozygous line is demonstrated by line 1 starting with a single copy plant and screening for a homozygous plant in T 1. When T 0 is a low copy number (2–3) plant a single copy plant can often be identified in the T 1 generation first after which a homozygous plant can be selected in T 2 (line 2).get price
