Evaluation of Herbicide Tolerance and Interference Potential Among Weedy Rice GermplasmShrestha, Swati 10 August 2018 (has links)
Weedy red rice is conspecific weed of rice, identified as a threat to global rice production. As weedy rice is more tolerant to stresses than cultivated rice and has wide genetic and morphological variation we hypothesized that weedy rice has high herbicide tolerance and weed suppressive potential. Herbicide tolerance and weed suppressive potential of 54 weedy rice accessions were evaluated and the traits were associated with molecular markers. Accessions B2, B20 and S11 showed high tolerance to glyphosate and B49, B51 and S59 had high tolerance to flumioxazin. All the accessions were controlled 100% with 1311g a.i/ha (1.5x) rate of glufosinate. Accession B2 inhibited the growth of barnyardgrass and amazon sprangletop by more than 50% indicating its high weed suppressive potential. Nei’s gene diversity and Shannon’s information index among the weedy rice accessions were found to be 0.45 and 0.66 respectively indicating high genetic diversity among weedy rice accessions.

Using weed-suppressive, chromosome substitution (CS) cotton as a supplemental weed management strategyFuller, Mary Gracen Alexandra 06 August 2021 (has links)
Cotton is a valuable fiber crop around the world used to create fabrics, oils, and currency. The threat of herbicide resistant (HR) weed populations is precarious for cotton production. The overreaching objective of this study was to phenotype potentially allelopathic chromosome substitution (CS) lines to determine competitive accessions. The identification of competitive cotton lines would be useful in the development of alternative weed control tools. Twelve CS lines (CS-49, CS-38, CS-34, CS-39, CS-27, CS-13, CS-50, CS-26, CS-25, CS-43, CS-46, and CS-23) along with the parent line (TM1) and two conventional varieties (UA48 and Enlist) were screened in a greenhouse using the stairstep structure. Eight CS lines were then selected to test in the field and analyzed in the lab to identify allelochemical exudates using HPLC. Results of this study provide a greater insight into the nature of allelopathy and its potential usefulness in cotton crops.
