Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse and laboratory experiments were conducted with theree domestic and nine wild proso millet (Panicum milicaceum L.) biotypes. Growth during 70 days after planting was evaluated using the Richards function, which characterized relative differences in growth. Significant differences in shoot dry wight and leaf area expansion were observed for proso millet biotypes. The average shoot dry weight RGR was 0.095 g-1 day -1. AGR of shoot dry weight ranged from 0.24 to 0.45g day -1. Proso millet biotypes significantly differed in leaf area 26 DAP. Shoot dry weight and leaf area RGR did not differ among biotypes while differences were observed for AGR. Proso millet biotypes did not differ for specific leaf area although differences were detected for leaf area ratios. Domestic biotypes were shorter than wild biotypes. Tiller number varied from 2 to 4 per plant. Plant biomass partitioning results indicate different pattern of dry weight accumulation. Reproductive development started between the third and fourth week after planting, depending on biotype. Seed germination ranged from 28 to 100% 14 days after incubation. Seed coat as a percent of total seed biomass varied between 12.2 and 29.8%. Black seeded biotypes had different germination rates that ranged from 17 to 91% but no differences were observed for seed coat percent and seed weight. Shoot dry weight, leaf area, and biomass partitioning early growth differed among biotypes. The competitive ability detected between Canada-Rosemount black seeded and Colorado-Weld Country tan seeded biotypes suggests a greater competitive ability for the Canada biotype. The genetic variation based on AFLP technique detected two distinct groups: (i) all domestic biotypes with black and olive seeded wild biotypes and (ii) tan seeded biotypes with a Wyoming brown seeded wild biotype. The genetic diversity observed among biotypes may correlate with differences in growth and competitive ability DNA research was conducted last in this thesis, future research of this type should begin with DNA assessment to detect the most diverse domestic and wild biotypes. This would allow for more focused research on growth analysis and competition studies.

This book was released on 1987 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild proso millet (Panicum miliaceum L.) is a serious weed recently infesting sweet corn fields in the Willamette Valley of western Oregon. Field and greenhouse experiments were conducted to determine the importance of seed depth in the position of the growing point of wild proso millet seedlings and in the performance of five herbicides. The effects of atrazine (6-chloro-N-ethyl-N'-(1- methylethyl)-1,3,5-triazine-2,4-diamine) and tridiphane (2-(3,5- dichloropheny1)-2-(2,2,2-trichloroethyl) oxirane) combinations and alachlor (2-chloro-N-(2,6-diethylphenyl-N-(methoxymethyl)acetamide) soil placement on wild proso millet control were also studied. Shallow seed depths (0 and 3 cm) resulted in more seedlings with the growing point above the soil surface than deeper depths. Mesocotyl length was also directly influenced by seed depth. Wild proso millet emerged from the deepest seed placement which was 15 cm. Seedlings from seeds deeper than 6 cm emerged slower than from shallower seeds. In the first field experiment, seed depth did not influence the performance of alachlor, atrazine, tridiphane, pendimethalin (N-(1- ethylpropy1)-3,4-dimethy1-2,6-dinitrobenzenamine), and EPTC (S-ethyl dipropyl carbamothioate). In the second field experiment, seed depth influenced the performance of these herbicides. Pendimethalin (2.0 kg/ha), atrazine + tridiphane (1.1 + 0.5 kg/ha), alachlor (2.2 kg/ha), and EPTC + dichlormid (3 kg/ha) were less effective at 1 cm than at 6 or 11 cm wild proso millet seed depth. Higher rates of the same herbicides were more effective on plants from seeds at 1 cm than from either 6 or 11 cm. This suggests that higher rates are needed to control wild proso millet from shallow seeds. Perhaps the growing point above the soil surface is reducing the effectiveness of soil applied herbicides on wild proso millet. Early postemergence applications of atrazine (0.56, 0.84, 1.68, and 2.24 kg/ha) and tridiphane (0.28, 0.56, and 0.84 kg/ha) alone and in combinations decreased wild proso millet dry weight and height. Plants treated with atrazine or tridiphane alone did not differ in height or dry weight. There was synergism in the atrazinetridiphane combinations. Shoot exposure was more damaging to wild proso millet seedlings than root exposure at the three alachlor rates used (0.1, 0.5, and 1.0 ppm). Shoot or both shoot and root exposure caused equal reductions in height or dry weight of wild proso millet. These results indicate that alachlor should remain in the shoot region of emerging seedlings for best wild proso millet control.

This book was released on 2015 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proso millet (2n=4x=36), an allotetraploid self-pollinated cereal with highest water-use efficiency, is the best rotational crop in dryland production system in the semi-arid High Plains of the USA and elsewhere in the world. Breeding and genomic research in this crop is very limited. Overall goal of this dissertation is to develop proso millet genetic and genomic resources (germplasm characterization, molecular marker development, and QTL mapping) for the genetic improvement through conventional and molecular breeding. For marker development, a total of 348 SSRs were developed for proso millet using cross-species genomic resources. In genetic diversity, 90 diverse genotypes, considered as proso millet core collection, were clustered into three groups based on 1287 SSR marker alleles, amplified by the 100 SSR markers. Genotypes were clustered corresponding to their geographic origin, pedigree and morpho-agronomic traits with few exceptions. In germplasm characterization, seventy-seven of the 90 genotypes showed a wide range of variation for nine morpho-agronomic traits and formed six clusters based on the phenotypic data. Genotypes were significantly different for all the traits across locations and many traits were highly correlated. Genotypes with resistance to lodging and grain shattering, two very important traits in proso millet breeding, were identified. The fourth objective, the first genetic linkage map of proso millet was developed using 833 GBS-SNP markers in 93 RILs and the map consisted 18 major and 84 minor linkage groups. The 18 major linkage groups spanned 2137 cM of proso millet genome with an average density of 18 cM. A total of 17 QTLs (LOD = 2.55 to 3.98) for seven morpho-agronomic traits were detected, which explained 13.2 to 34.7% phenotypic variance. DNA markers flanking the QTLs were identified, which could be useful in marker-assisted selection of these traits. The results of these studies will have significant utilization in proso millet breeding, genetics, and genomics research.
