Effect of far-red radiation on flowering of saccharum spp. hybrids
(1990)
Many tropical sugarcane clones (Saccharum spp. hybrids) are unavailable for hybridization because of poor flowering. Methods are required to improve the flowering of such clones. This study was conducted to determine ...
Optimum family felection for net merit grade : stage 2 trials BS45S
(1996)
Mass selection of individuals in seedling or early clonal stage trials is routinely used in most sugarcane improvement programs throughout the world. It is, however, inefficient as the Heritability of cane yield on a ...
Fine mapping of major rust resistance gene in cultivar R570 with a view towards it closing through map-bases chromosome walking
(1999)
A major gene for rust resistance has been identified in cultivar R570 (Daugrois et ai, 19%). Rust disease is caused by the fungus Puccinia malenocephala Syd P. Syd and is distributed worldwide. Inheritance of resistance ...
Selection of a non-sugarcane gene for control of canegrubs : SRDC final report BS95S
(1996)
Four types of non-sugarcane genes were investigation for potential toxictiy to canegrubs. They were: toxins from the bacterium Bacillus thuringiensis (Bt); plant proteinase inhibitors; plant lectins; and avidin. Each of ...
Best linear unbiased prediction as a method for predicting cross potential : SRDC final report BS119S
(1999)
Until recently, BSES breeders used an empirical formula to assess the breeding potential of a parent (Hogarth and Skinner, 1986). Although this method uses data from many sources, it needs to draw on data accumulated for ...
The role of Pythium species in yield decline in Southern cane growing districts : SRDC final report BS80S
(BSES, 1998)
Yield decline has been demonstrated in all established canegrowing regions of Queensland. Field and glasshouse studies with soil fumigants have shown that yield decline is largely caused by soilborne biological factors. ...
Identification of unknown root pathogens responsible for sugarcane yield decline : SRDC final report BS73S
(BSES, 1996)
Sugarcane yield decline (YD) is characterised by poor root development ( a lack of fine root growth, root discolouration) and poor root health. Previous YD research implicated the involvement of unrecognised pathogens in ...
High efficiency production of transgenic sugarcane plants
(1994)
The efficiency of gene transfer into embryogenic callus of sugarcane has been increased tenfold by optimisation of particle bombardment conditions, and there is a corresponding increase in stable transformation frequencies. ...
