The Precautionary Principle (PP) has been invoked to advocate preventative action to forestall possible harm even before the likelihood or the possible extent of the latter has been scientifically well established. This principle is highly contested because it may hamper innovati...

Increasing biomass accumulation is becoming a major objective of most bread wheat (Triticum aestivum L.) breeding programs worldwide. This study addresses the changes caused by breeding in the pattern of wheat growth and its relationship with the presence of Rht dwarfing alleles....

Potato is one of the most important crops in the world, including in the tropics. Potato requires low temperatures or cool climate for optimum tuber yield, which in the tropics, can be obtained mostly in high altitude growing areas. The limitation of land availability for potato ...

Smooth-leaved, regular-flowering dwarf mutants were observed among the progeny of a cross between two normal red clover clones. This dwarf characteristic was controlled by one gene and is recessive to normal growth. The symbol dw1 is proposed for this character. Dwarf plants resp...

Improvement of forage nutritive value through breeding should lead to enhanced livestock productivity but often results in reduced agronomic performance. This study investigated the potential for simultaneous improvement of nutritive and agronomic traits in timothy (Phleum praten...

A new resistance ( R ) gene to powdery mildew has been identified and characterized in a population derived from the wild potato species, Solanum neorossii under natural infection in the greenhouse. The segregation of resistance has revealed that this R gene is controlled by a si...

Microspore response of three- way cross maize hybrid genotype 3AL/95 ( Zea mays L. ) was studied under simplified isolation and culture conditions. Fertile plant production was achieved through abundant plant regeneration. As a total, microspores of 160 tassels were inoculated an...

1.Plants of Callistephus chinensis cv. ‘Giant Comet’ were subjected to photoperiods of 8 or 16 hours. In short day (SD) a much greater number of leaves was formed than in long day (LD) before the terminal inflorescence was initiated. By transferring plants from LD to SD at weekly...

Megasporogenesis and megagametogenesis in diploid tuber-bearing Solanum species hybrids were studied and illustrated in detail. Megagametogenesis followed the normal or Polygonum type of embryo sac development. In megasporogenesis a few regularly occurring deviations from what is...

We estimated genetic and environmental variance components for fruit quality traits (cluster weight, berry weight, soluble solids content, total sugar content, sugar composition, free acid content, total amino acid content, amino acid composition), and a functional trait (gamma-a...

DNA amplification fingerprinting (DAF) was used to characterize different Cynodon dactylon (L.) Pers. cultivars and accessions and evaluate the genetic diversity among them. DAF analyses of some well known cultivars used in South Africa, i.e. Sahara, Tifway, Tifgreen, Harrismith,...

Seedcoat colour in greengram (Vigna radiata (L.) Wilczek.) is a useful marker for genetic studies and varietal identification. Its mode of inheritance was examined in five crosses among nine parents which differed for seedcoat colour. Four of the parents had sap green seedcoat co...
