Row Space

Soybean [Glycine max (L.) Merr.] yield is responsive to changes in plant population and row spacing. The objective of this study was to compare some agronomic traits of soybean cultivated in two different row spaces in a field in St Pauls, NC. Among the traits, total seed weight showed the highest level of variation than others in both 25 cm (97.31%) and 50cm (60.23%) row space. The lowest co-efficient of variation, 5.06% at 25 cm and 11.54% at 50 cm were found for days to flowering. Mean value showed that plants grown in 25 cm row space have a higher 100-seed and total seed weight than those grown in 50 cm row space. Plants grown in 50 cm row space had a slightly increased mean plant height compared to those grown on 25 cm. Plants grown in 50 cm row space had greater pod and seed numbers compared to those grown on 25 cm. Comparisons of the agronomic parameters between 25 and 50 cm row space employed by two-tailed t test (type 2; α = 0.05) showed that there are significant differences in days to germination, days to flowering, number of seeds, and total seed weight between plants grown in 25 cm vs. 50 cm row space; while plant height and number of pods were not differ significantly. However, further research may reveal a system for soybeans cultivation in the future which would increase the probability of obtaining maximum yields with narrow rows.

A pot experiment was conducted under rainfed condition to study the effect of water hyacinth compost on the morpho-physiological parameters of soybean (Glycine max L.) at the Teaching and Research Farm of Faculty of Agriculture and Veterinary Medicine, Imo State University, Owerri. The treatments were control (T1) 100g (T2), 150g (T3) and 200g (T4) of water hyacinth compost and replicated four times. The treatments were arranged in Complete Randomized Design (CRD). The parameters measured were plant height, number of leaves, leaf area (cm2), leaf area index, relative growth rate (RGR), Net assimilation rate (NAR), shoot dry weight(g), yield and yield components (Number of pods, pods weight, 100 seed weight). The results obtained indicated that T3 significantly produced highest plant height (57.6cm) compare to control. While it was observed that T4 (200g) significantly produced the highest number of leaves (233.25), leaf area (631.80cm2), shoot dry weight (15.445g), number of pods (129.75), pod weights (25.38g) seed weight (7.23g) and yield (0.72kg/ha) relative to control and other treatment levels. Root parameters were also significantly improved by the rates of water hyacinth application compared to control. It will be worthy to note that there was no nodulation perhaps that was why the yield was poor. The results showed that soybean growth can effectively be improved with incorporation of water hyacinth into soil.

Genetics of agronomic traits in safflower was determined using 6×6 full diallel population. Data were recorded on days to flowering, days to maturity, plant height, primary branches per plant, head diameter, number of heads per plant, number of seeds per head, 1000-seed weight and seed yield per plant. Variance components showed that days to maturity and heads per plant were largely controlled by dominance gene effects, whereas 1000-seed weight, plant height and seeds per head were governed by additive type of gene action. The results also revealed both additive and non-additive types of gene actions for remaining traits. The significant mean squares of reciprocal crosses for days to flowering, head diameter, number of seeds per head, 1000-seed weight and seed yield per plant suggested that maternal inheritance also played an important role in the inheritance of these traits. Significant general combining ability for yield revealed that genetic improvement through accumulation of desirable alleles from parents in the target genotype using appropriate selection methods would be desirable in safflower.

Abstract Background Soybean [ Glycine max (L.) Merr.] is a legume of great interest worldwide. Enhancing genetic gain for agronomic traits via molecular approaches has been long considered as the main task for soybean breeders and geneticists. The objectives of this study were to evaluate maturity, plant height, seed weight, and yield in a diverse soybean accession panel, to conduct a genome-wide association study (GWAS) for these traits and identify SNP markers associated with the four traits, and to assess genomic selection (GS) accuracy. Results A total of 250 soybean accessions were evaluated for maturity, plant height, seed weight, and yield over three years. This panel was genotyped with a total of 10,259 high quality SNPs postulated from genotyping by sequencing (GBS). GWAS was performed using a Bayesian Information and Linkage Disequilibrium Iteratively Nested Keyway (BLINK) model, and GS was evaluated using a ridge regression best linear unbiased predictor (rrBLUP) model. The results revealed that a total of 20, 31, 37, 31, and 23 SNPs were significantly associated with the average 3-year data for maturity, plant height, seed weight, and yield, respectively; some significant SNPs were mapped into previously described loci ( E2 , E4 , and Dt1 ) affecting maturity and plant height in soybean and a new locus mapped on chromosome 20 was significantly associated with plant height; Glyma.10g228900 , Glyma.19g200800 , Glyma.09g196700 , and Glyma.09g038300 were candidate genes found in the vicinity of the top or the second best SNP for maturity, plant height, seed weight, and yield, respectively; a 11.5-Mb region of chromosome 10 was associated with both seed weight and yield; and GS accuracy was trait-, year-, and population structure-dependent. Conclusions The SNP markers identified from this study for plant height, maturity, seed weight and yield can be used to improve the four agronomic traits through marker-assisted selection (MAS) and GS in soybean breeding programs. After validation, the candidate genes can be transferred to new cultivars using SNP markers through MAS. The high GS accuracy has confirmed that the four agronomic traits can be selected in molecular breeding through GS.
