Heterosis Utilization of Interspecific Hybrids Between Autotetraploid Sorghum and Johnsongrass

doi:10.3321/j.issn:1000-7091.2000.02.001

Abstract

Abstract: Interspecifichybrids between autotetraploid Sorghum (S.bicolor L. Moench) and Johnsongrass (S.halepense L. Pers) were produced. The morphological characteristics,heterosis and the forage value of interspecifichybrid were performed. The results showed thathybrids exhibited greatheterosis on growth potential and biomass (70.0%~90.0%). No evident differences were observed from F₁ to F₃hybrid withhigh biomass compared to parents, and the low generationhadhigh forage quality.

Key words: Autotetraploid Sorghum, Interspecific cross, Heterosis
