Seedlings of both KS8 and N32 sorghum [Sorghum bicolor (L.) Moench] were high in dhurrin [p-hydroxy-(S)-mandelonitrile-BD-glucoside] and thus in hydrocyanic acid potential (HCN-p), but the HCN-p of mature leaves from field-grown plants of KS8 was only about one-tenth as high as that of N32. A study of the inheritance of this large difference between KS8 and N32 revealed that a single major gene...

Therefore, enhancing the quality of grain sorghum stover may offer an opportunity to add value to the overall Nearly 3 million hectares of grain sorghum [Sorghum bicolor (L). system when post grain harvest stover residue is used Moench] are harvested in the USA each year. It may be possible to add value to crop and animal systems by enhancing the digestibility as a forage base for livestock. of...

Selecting and cultivating the crops/varieties that can tolerate water salinity is potentially animportant strategy to save fresh water resources and maximize the crop yield in salt affected areas.To evaluate the responses of 36 sorghum lines and cultivars to salinity stress, two fieldexperiments were conducted in non-stress (EC=2 dS/m) and salinity stress conditions (EC=12dS/m) using randomized...

Funnell, D. L., and Pedersen, J. F. 2006. Reaction of sorghum lines genetically modified for reduced lignin content to infection by Fu.sarium and Alternariu spp. Plant Dis. 90:331-338. Two genes conferring the brown midrib (bmr) trait had been backcrossed into six elite sorghum lines, resulting in reduced lignin in the hrnr lines when compared with the wild-type parent. Seed and leaf tissue fro...

In sorghum [Sorghum bicolor (L.) Moench], development of male-sterile versions (A-lines) the seed parents (B-lines) is a tedious and time-consuming process limiting opportunities for improvement new parents. Assessment value potential parent requires testcross hybrid evaluations, but because male fertility these lines, conventional methods are inadequate to generate required testing. Mechanisms...

The research work on sweet sorghum carried out at the Nimbkar Agricultural Research Institute (NARI) during last twenty-five years has been summarized. American lines were crossed with a local Indian fodder/grain variety to produce varieties with a juicy stalk and good quality grain. Further breeding was carried out to produce varieties and hybrids giving high yield of good quality grain while ...

Sorghum breeding programs are based predominantly on developing homozygous lines to produce single cross hybrids, frequently with relatively narrow genetic bases. The adoption of complementary strategies, such as diversity study, enables a broader vision the structure germplasm. purpose this study was evaluate sorghum using analysis, principal components (PC) and clustering analyses. A total 16...

The present investigation was conducted to assess the magnitude of heterosis rabi sorghum (Sorghum bicolor (L.) Moench) developed by crossing four lines and twelve testers (in a line × tester design) produce 48 F1 cross combinations at Sorghum Improvement Project, MPKV., Rahuri, Maharashtra. To identify high-yielding Rabi hybrids, promising hybrids were sorted out based on positive significant ...
