The use of in vitro potato shoot cultures for protoplast isolation is desirable for consistent protoplast qualities. Ethylene build-up in the culture vessels causes problems for leaf growth (e.g. decreasing leaf surface, dry weight and chlorophyll) in shoot culture. Fifty to one hundred µM Silver thiosulfate (STS) produced a larger leaf area as a source of plant material for protoplast isolatio...

Tef [Eragrostis tef (Zucc.) Trotter] is the major cereal crop in the Horn of Africa, especially in Ethiopia where it is a staple food for over 60% of its 90 million population. The crop performs better than other cereal crops under extreme environmental conditions. The grain of tef is not only nutritious but also gluten-free, the cause for celiac disease, which affects humans world wide. The ob...

in order to evaluate the effects of different levels of water and plant density on yield, yield components, morphological and physiological characteristics of a new corn hybrid (ksc 500), an experiment was carried out in 2006 in karaj area. the experimental design was split plot based on randomized complete blocks design with three replications. main plots were three irrigation levels: 75%, 100...

Castor is one of neglected African oil crops with little research attention in Nigeria. In the present research, eighty-six castor genotypes were evaluated at three locations in Niger State, Nigeria. The aim was to estimate the extent of genetic variability and also to examine the associations among the seed yield and its components. The treatments were laid out in an Alpha Lattice Design with ...

A linkage map of pea was constructed based on a 104 RIL population derived from the cross combination Wt10245 x Wt11238. The map, which consisted of 204 morphological, isozyme, AFLP, ISSR, STS, CAPS and RAPD markers, was used for interval mapping of the QTLs controlling the stem length and internode number of pea. In the characterization of a given QTL, we included an identification of its posi...
