Molecular characterization of some brinjal genotypes (Solanum melongena L) using simple sequence repeat (SSR) markers
To analyze genetic variability of 48 brinjal genotypes by Simple Sequence Repeat (SSR) markers, four primers named smSSR01, smSSR03, smSSR11 and smSSR14 were selected for analyze the data. Four primers generated clear bands and a total of 44 alleles were detected among the 48 brinjal genotypes (9.0 to 14.0 alleles per locus with a mean of 11.0 alleles per locus). According to Nei’s (1973), the highest level of...

Effects of fungicide treatments against Anthracnose in Calabrian (southern Italy) Olive Orchards during 2014-2015
In recent years, severe natural olive anthracnose infections have been observed in orchards of Southern and Central Italy, favoured by mild and rainy seasonal trends, making disease control with the sole use of copper fungicides difficult. Besides, European restrictions in the use of copper compounds for eco-toxicological aspects have forced researchers towards the use of available plant protection products. Thus, 2...

Indigenous rhizobia strains: The silver bullet for enhanced biological nitrogen fixation and soybean (Glycine max (L.) Merr. ) yield under different soil conditions in South Kivu province, Democratic Republic of Congo
Soybean is an important crop in the Democratic Republic of Congo, a country faced with high levels of war induced malnutrition but its productivity is limited by poor soil fertility coupled with low access to nitrogen mineral fertilizers. Commercial rhizobia strains introduced in 2010 failed to adapt and increase soybeans yields at desired level. We studied the performance of six indigenous rhizobia strains in enhancing...
