“…Residues and extracts of rice plants also inhibited the germination and growth of several plant species (Tamak et al, 1994;Kawaguchi et al, 1997;Das and Goswami, 2001;Ebana et al, 2001;Khan et al, 2001;Mattice et al, 2001;Kato-Noguchi, 2002), indicating that rice may have chemicals involved in allelopathy. However, little information is available on allelopathic active substances in rice plants.…”

“…A total of 16 potential compounds involving phenolic acids were detected in rice 16 . The chemical compounds with allelopathic effects on barnyardgrass were isolated from rice leaves by HPLC 12 and roots by GC-MS 18 . These chemical approaches have provided the candidate compounds associated with rice allelopathy.…”

To analyze the genetic control of allelopathy in rice, we examined the quantitative trait loci (QTL) controlling allelopathic effects using a F 2 population of the cross between PI312777 and Rexmont, which exert highly suppressive and less suppressive effects respectively, on mono-and di-cot weed species in the field. The allelopathic effects were assessed using water-soluble leaf extracts from rice plants at the six-leaf growth stage. A highly positive correlation was detected between the suppressive effects of rice leaf extracts on the root growth of lettuce and ducksalad. Seven QTL controlling allelopathic effects of rice on lettuce used as a test plant were identified on chromosomes 1, 3, 5, 6, 7, 11 and 12. One of the QTL on chromosome 6 exerted the largest effects on the expression of the allelopathic effects and explained 16.1% of the total phenotypic variation. The other 6 QTL explained the variation in the range from 9.4 to 15.1%. A multiple QTL model estimated that 5 QTL with LOD scores higher than 3.0 explained 36.6% of the total phenotypic variation. Digenic interactions in 5 pairs among 7 QTL were detected. In this paper, we examined the use of allelopathy in rice as a potential method for biological control of weeds.Discipline: Plant breeding Additional key words: allelopathy, Oryza sativa L., quantitative trait loci, RFLP mapping, water-soluble extracts JARQ 37 (2), 77 -81

Weed control with herbicides is not possible in several systems including control of wild oat (Avena fatua L.) in tame oat (Avena sativa L.), red rice (Oryza sativa L. var. sylvatica) in rice (Oryza sativa L.), and in organic systems. Competitive crop cultivars can be used to manage weed competition if selective weed control by herbicides is not possible. However, most existing competitive crop cultivars often have low weed‐free yield and poor grain quality. We hypothesize that the progeny of a cross between a competitive forage‐type oat cultivar and a high‐yielding and high grain quality grain oat cultivar will have high yield and good grain quality as well as high competitive ability (CA). The objective of this study was to evaluate progeny lines from a cross between a tall, competitive, forage‐type oat cultivar with a semidwarf, high‐yielding milling oat for their CA against wild oat. A field study was performed in two locations in Saskatoon, SK, Canada, in 2008 and 2009 using seven progeny lines and the two parents. Oat was seeded with and without wild oat at a target crop and weed density of 250 plant m‐2 in a randomized block design with four replicates. All the genotypes were high yielding and did not differ in grain yield or quality either in weed‐free or weedy conditions. Some of the tall (CDC Baler, SA050498, and SA050479) and short (SA050040 and Ronald) genotypes had high average grain yield under both weed‐free and weedy conditions compared with the other genotypes. The tall oat line SA050479 was among the most weed suppressive, which resulted in less wild oat biomass. The seedling total leaf area, crop height, and the seedling third leaf area were negatively correlated with wild oat biomass. This study demonstrates that a cross between a high‐yielding and a highly competitive genotype can result in progeny with high CA, yield, and crop quality.
