Identification of PCR-based DNA markers flanking three low phytic acid mutant loci in barley

June 2009

  Phytic acid (PA) is the most abundant form of phosphorus (P) in cereal grains. PA chelates mineral cations to form an indigestible salt and is thus regarded as an antinutritional agent and a contributor to water pollution. Grain with low phytic acid (lpa) genotypes could aid in mitigating this problem. In barley, more than 20 lpa mutant lines have been isolated, representing at least 6 different genetic...

Grain filling rate is limited by insufficient sugar supply in the large-grain wheat cultivar

May 2009

  Wheat grain yield can be limited by source, sink or by both. Inconsistency of the previous results reflects the interactions between genotypes and environments. In north China where the hot, dry wind was frequent during grain filling, new winter wheat cultivars with large grains suffer from loss of grain weight quite often because the grain filling rate (GFR) is low. In the present study, the carbohydrate...

Intercropping and its application to banana production in East Africa: A review

April 2009

  Bananas are very important in Kenya for domestic consumption and export. They are extensively grown where they are mainly intercropped with short term crops. There has been an increase in the grower interest in using intercropping-growing two or more crops simultaneously on the same land  in the development of new cropping systems for their land. Intercropping could reduce management inputs and result in...

Resistance in Kenyan bread wheat to recent eastern African isolate of stem rust, Puccinia graminis f. sp. tritici, Ug99

April 2009

Stem or black rust, caused by Puccinia graminis, has historically caused severe losses to wheat (Triticum aestivum) production worldwide. The causal race, commonly known as Ug99 and designated as TTKS based on the North American nomenclature, carries virulence for several genes commonly present in wheat germplasm. All Kenyan germplasm are known to be susceptible or partially susceptible to Ug99 although no proper...

Genetic polymorphism in exotic safflower (Carthamus tinctorious L.) using RAPD markers

March 2009

  Safflower is a drought tolerant annual oil crop and this gives it an advantage over the other crops in the drier parts of Kenya. It is valued worldwide as a source of high quality vegetable oil. In the past, characterization of safflower using molecular markers has been limited. The objective of this study was to evaluate the degree of polymorphism in 36 safflower accessions using RAPDs. Sixty-one...
