GGE biplot phenotypic stability analysis of soybean [Glycine max (L.) Merril] genotypes

The study on genotypes by environment interaction (GEI) and stability analysis was conducted to determine the G, E, and GEI variance magnitudes. The experiment was carried out at three locations in two consecutive years on 26 soybean genotypes using randomized complete block design (RCBD) design with three replications. The objectives were to (i) estimate the magnitudes of G, E, and GEI effects, (ii) stability analysis...

Influence of environment on soybean [Glycine max (L.) Merr.] resistance to groundnut leaf miner, Aproaerema modicella (Deventer) in Uganda

Groundnut leaf miner (GLM) [Aproaerema modicella (Deventer)] is a serious problem for soybean cultivation in Uganda causing yield losses of up to 100%. The use of soybean [Glycine max (L.) Merr.] cultivars resistant to GLM attack is an important strategy in the integrated pest management program. The aim of this study was to determine the environment × genotype interaction influence on the soybean resistance...

Curauá genetic diversity in germplasm banks and natural populations

Ananas comosus var. erectifolius (L. B. Sm.) Coppens & F. Leal, populary known as curauá, is a bromeliaceae, found in the Amazonian flora. It is of great commercial interest, mostly for the automobile industry. Despite the curauá’s potential, little has been done to conserve its germplasm. For this, it’s necessary to know its genetic variability. An efficient way of knowing it is to use...
