甜高粱亦名糖高粱,茎内富含大量糖分,是较理想的饲料、糖料和能源作物。甜高粱茎秆产量高,子粒产量低;而普通粒用高粱子粒产量高,茎秆产量低。将二者有机地结合于一体,对培育优良的亲本材料,丰富遗传基础,配制粮秆双高产的杂交种是十分有益的。本文以普通粒用高粱为母本,以甜高粱为父本进行杂交,看其亲本配合力和杂种优势表现及其性状相关,探讨二者杂交培育高产甜高粱杂交种及亲本的可行性。
Sweet sorghum, also known as sugar sorghum, stems rich in sugar, is the ideal feed, sugar and energy crops. Sweet sorghum has high yield of stalks and low yield of grain, while common grain uses high yield of sorghum and low yield of stalks. The combination of the two organically is very beneficial for cultivating good parental materials, enriching the genetic basis and formulating double high yield hybrids with grain and straw. In this paper, we use the common grain sorghum as the female parent and sweet sorghum as the male parent to observe their parents’ combining ability and the heterosis performance and their traits, and discuss the feasibility of their hybridization to breed sweet sorghum hybrids and their parents.
