Book Synopsis Selection for Soybean Seed Yield with Molecular Markers by : Joseph Richard Byrum
Download or read book Selection for Soybean Seed Yield with Molecular Markers written by Joseph Richard Byrum and published by . This book was released on 1999 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular markers may facilitate the identification of and selection for quantitative trait loci (QTL) that control economically important traits. The objective of the study was to compare the efficiency of selection among soybean [Glycine max (L.) Merrill] lines for seed yield based on single replication progeny-row-yield tests (PRYT), molecular marker loci selected by pedigree analysis, and a combination of PRYT and molecular marker data. A total of 380 random F3-derived lines from three populations were evaluated in the PRYTat Ames, IA, in 1997 and were genotyped for simple sequence repeats (SSRS) that had been chosen by pedigree analysis for their association with seed yield. The lines were divided into 13 tests for evaluation in 1998 at five or six Midwest locations in replicated yield tests. The average phenotypic correlation coefficient between the mean yield of lines in the 1998 test and their PRYT yield was 0.24, molecular marker score was 0.19, and index value was 0.35. The index was superior on the average to the PRYT or molecular marker score individually for selection of the highest yielding lines in the 1998 tests. The selection differential based on the index was superior on the average to the PRYT or molecular marker score individually in two of the three populations. Marker-QTL associations established by pedigree analysis should be useful alone or in combination with PRYT for selection among lines for seed yield in a cultivar development program.

Book Synopsis Assessing the Efficiency of Phenotypic and Molecular Genotype Selection Methods for Complex Traits in Soybean by : Catherine Nyaguthii Nyinyi
Download or read book Assessing the Efficiency of Phenotypic and Molecular Genotype Selection Methods for Complex Traits in Soybean written by Catherine Nyaguthii Nyinyi and published by . This book was released on 2011 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean [Glycine max (L.) Merrill] is an important source of protein and oil for both nutritional and industrial applications. Increasing seed yield and protein concentration is the main goal of many soybean breeders to meet market demands. Soybean breeders have occasionally succeeded in producing high yielding cultivars with increased protein content using conventional means despite the negative correlation that exists between these two traits. The efficiency of breeding for seed yield and protein concentration improvement in soybean could be increased using marker assisted selection (MAS) breeding strategies to select genotypes containing favorable alleles for faster cultivar development. The objective of this study was to identify quantitative trait loci (QTL) associated with seed yield, and separately, seed protein concentration and then compare phenotypic selection (PHE) and MAS approaches for seed yield and protein concentration improvement. Two hundred and eighty two F5 derived recombinant inbred lines (RILs) were developed from a cross of Essex [centered x, actual symbol not reproducible] Williams 82 and genotyped with 1586 single nucleotide polymorphism (SNP) markers. The population was divided by days to maturity (10 days) into three tests (early, mid and late) each with 94 genotypes, with one genotype overlapping in maturity in the mid and late tests. In 2009, the three tests, parents and checks were grown in a randomized complete block design (RCBD) in: Fayetteville, AR; Harrisburg, IL and, Knoxville, TN replicated three times, and evaluated for seed yield and protein concentration. Data were combined within each test across three locations and analyzed using the MIXED procedure of SAS to determine that there were significant genotypic differences among RILs. Composite interval mapping (CIM) detected nine seed yield and ten protein concentration QTL which may be good candidates for MAS as they were environmentally stable. Selections to compare PHE, and MAS for seed yield and protein concentration provided 8 replicated field tests in four relative maturity groups grown in a RCBD replicated three times in three locations in Tennessee, in 2010. We demonstrated that both MAS and PHE may be used to select quantitative traits; however, more studies are required to optimize MAS for quantitative trait improvement.

This book was released on 1983 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient use of agricultural inputs involves correct decisions on what production systems would give optimum yields. Good management decisions can only be made by considering information provided by research on crop responses to management practices. Field studies were conducted to determine the influence of planting date, row spacing, cultivar, seed treatment, depressing plants with tractor tires, and planting patterns on yield, seed quality, and agronomic characteristics of soybeans (Glycine max (L.) Merr.). In Experiment 1 (1981 to 1982), treatments were five planting dates (May to July), row spacings (12,18, 38, and 76 cm), and cultivars ('Evans', 'Hodgson 78', and 'Corsoy 79'). The 18 cm plots were in pairs. One plot was planted with seed treated with Vitavax (5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide). 'Wells' was planted in Experiment 2 (1979 to 1980). Treatments were morning and afternoon, and growth stages when plants were depressed in 25 cm rows. In Experiment 3, four rippled canopies were compared with pure stands and blends of 'Wells II', 'SRF 200', and 'Gome' in 38 and76 cm row spacing in 1981 to 1982. In Experiment 4, six cultivars were planted in pairs in 38 cm rows, perpendicular to each other. In Experiment 5, seed from Experiment 1 was assayed for Diaporthe and Phomopsis infection and for germination. Delayed planting reduced yield. Narrow rows yield highest. Cultivars did not differ in yield. Yield in late planted narrow rows, with 'Evans' and 'Hodgson 78', was not reduced as much as in the 76 cm rows. Seed treatment did not influence yield or other characteristics. Morning and afternoon treatments were not different. Depressing plants did not reduce yield until flowering. Since most postemergence applications are done before flowering, yield reduction is compensated for by adjacent rows. Canopy designs were not different in yield. Light penetration was not affected by canopy designs. Crisscross planting did not affect yield. Direction of row changed competing ability of cultivars. Delayed planting reduced Phomopsis infection and improved germination. Seed quality in narrow rows was equal to or better than in wide rows. 'Evans' had more infection and lower germination than 'Corsoy 79'. Full season cultivars or delayed planting produced seed of good quality.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative trait loci (QTL) controlling seed yield in soybean [Glycine max (L.) Merr.] have been difficult to confirm among populations. Our objective was to determine whether a method of marker-assisted selection (MAS) for seed yield in elite lines would be applicable to selection in soybean plant row yield trials (PRYTs). Lines from two populations with elite parents were grown in PRYTs in 2008 and tested with markers to identify quantitative trait loci (QTL) associated with seed yield. The first population was tested with 53 single nucleotide polymorphism (SNP) markers and the second population with 26 SNP markers. F-tests were conducted to determine which loci were significantly associated with seed yield in the PRYTs. Lines from each population were then selected from the PRYTs to form five groups from each population: high and low seed yield phenotypes, high and low seed yield genotypes, and random. The five groups from each population were planted at eight diverse locations in 2009. In one population, the mean of the genotypic high group was not statistically different than the phenotypic high group. In the other population, the mean of the genotypic high group was within 90 kg/ha-1 of the mean of the phenotypic high group and was superior to the random group for seed yield. Even with the limited marker coverage, the genotypic selection method used in this study successfully identified lines in PRYTs that would not have been selected due to poor seed yield performance in 2008.
