A preliminary study on weed-suppressing rice breeding

Abstract

Abstract: A set of new breeding materials derived from PI312777 were established by using PI312777 rice accessions as weed-suppressing parents,and a rice breeding nursery was founded.Weed-suppressing rice plants were selected by evaluating their weed-suppressing effects and focusing on their agronomic characters in the field,and new varieties (or lines) of weed-suppressing rice were developed by evaluating the allelopathic potential of rice plants with applying specific secondary metabolite markers at late generations (after F4).A rice breeding method for weed-suppressing in South China,in which,main evaluation in the field and assistant evaluation by applying secondary metabolite markers,was mentioned.

Key words: Halophyte, Rrhizosphere, Salt content
