In conclusion, there was a high degree of genetic variation among genotypes compared to the variation due to location differences and GEI for all traits studied. The GEI was non-significant for early FSRY, indicating that the genotypes

had non-significantly different patterns of response to change in location and could be evaluated in terms of their mean response over locations. However, although for FSRY genotypes did not significantly interact with locations, there were apparent changes in rank of the genotypes at each location. The study results suggest that it is possible to make progress in breeding and selection for early storage root yielding cassava genotypes with resistance to CBSD and CMD. However, the presence of significant GEI for all the traits studied except FSRY will complicate selleck selection for early storage root yield genotypes with resistance to CBSD and CMD. The study was carried out with funds from the Alliance for a Green Revolution in Africa through the African Centre for Crop Improvement. We are grateful to the people that were involved in this research. “
“Ricebean (Vigna umbellata) is a grain legume crop grown

in hilly areas of Nepal and northeastern India. It is an underutilized crop that is grown only by resource-poor farmers. BKM120 It is grown as an intercrop with maize (Zea mays) in the kharif season. This small grain possesses enormous potential for becoming a more commonly utilized crop. The economic utility and production technology of ricebean have yet to be determined RVX-208 [1]. Among pulse crops, ricebean offers tremendous potential for expansion in northeastern India. As a short-duration and close-growing crop

with tender stems and green foliage even at maturity, ricebean is ideal for catch-cropping, intercropping and multiple-cropping systems and also serves as an excellent cover crop and green manure crop. Ricebean is reported to produce 3000 kg of grain and up to 8000 kg ha− 1 of dry herbage, serving as an important source of green forage during lean periods during April–June and November–December in northern India [2]. Ricebean grain, besides being a good source of protein with up to 24% seed protein concentration [3], has a very high in vitro digestibility of up to 82–85% [4]. In India, 30% of the cultivated land is considered acidic, where efficient fertilizer management is a problem. Of 49 million ha of acid soils, 26 million ha have a soil pH below 5.6 and 23 million ha have a pH between 5.6 and 6.5 [5]. The main causes of soil acidity in the region are intense weathering in association with humid climate and heavy precipitation [6]. In addition to temperature and precipitation, other factors affecting the process of acidic soil formation are topography and relief. Lime as an amendment for increasing nutrient availability in acid soils is considered to be the most important ameliorant for better growth, nodulation, and higher nitrogen fixation by legumes.
