Divergent Selection for Hydrocyanic Acid Potential in Sudangrass 1

Divergent Selection for Hydrocyanic Acid Potential in Sudangrass

Alteration in hydrocyanic acid potential (HCN-p) of the forage is one of the important objectives in sudangrass [Sorghum sudanense (Piper) Stapf] breeding programs. The effectiveness of recurrent phenotypic selection for increasing or decreasing HCN-p in sudangrass was evaluated in two cycles of individual plant selection in the cultivar 'Greenleaf. In cycle 1, HCNp means of the high and low po...

Inheritance of Seedling Hydrocyanic Acid Potential and Seed Weight in Sorghum - Sudangrass Crosses 1

The hydrocyanic acid potential (HCN-p) of sorghum [Sorghum bicolor (L.) Moench] plants is recognized as a heritable trait, but previous tudies on the mode of inheritance of HCN-p have produced inconsistent results. The objective of this study was to investigate the inheritance patterns of seedling HCN-p and also of seed weight in reciprocal crosses of sorghum and sudangrass [formerly S. sudanen...

Potential for Hydrocyanic Acid Poisoning of Livestock by Indiangrass

Hydrocyanic acid or prussic acid poisoning of livestock by sorghums [Sorghum bicolor (L.)Moenchl and sudangrasses [Sorghum sudanese (Piper) StapfJ is caused by the digestive liberation of hydrocyanic acid (HCN) from the cyanogenic compound, dhurrin [(S)-p-hydroxymandelonitrile ,8-D-glucopyranosideI found in tissue of these plants. Recent research documented that dhurrin is also present in india...

Seed Weight Influence on Seedling Hydrocyanic Acid Potential in Sorghum

Grain sorghum [Sorghum bicolor (L.) Moench) typically produces larger seeds than sudangrass [S. bicolor, formerly S. sudanense (Piper) Stapf]; and grain sorghum seedlings are higher in hydrocyanic acid potential (HCN-p) than sudangrass seedlings. Previous studies have shown a seed-parent effect on seed weight and HCN-p in reciprocal F, hybrids of sorghum X sudangrass. This study was conducted t...
