高粱杂交种主要经济性状,如产量、生育期、株高、抗逆性等的优劣,对于夺取高产、稳产十分重要。近年来,我省试验、试种了一批622A 系统新杂交种,具有产量高、抗丝黑穗病等优点,但也表现出秆软、不太抗倒伏等弱点。为进一步研究这些杂交种的优缺点及其产生的原因,注意在生产上扬长避短、使杂交种发挥更大的增产潜力。本研究用622A、3197A 和1981年从国际热带半干旱地区作物研究所新引进并经初步鉴定表现较好的KiffinumA(简称 KA)、M-40079A(简称079A)和 M-40081A(简称081A)为母本,组配了一批杂交组合,做了主要性状的配合力测定和农艺性状鉴定。现将试验结果报告如下。
The main economic traits of sorghum hybrids, such as yield, growth period, plant height, resistance and other advantages and disadvantages, for the capture of high yield, stable yield is very important. In recent years, our province experimented and tested a series of new hybrids of 622A system with the advantages of high yield and resistance to head smut, but also showed the weakness of stalk softness and less resistance to lodging. To further study the advantages and disadvantages of these hybrids and their causes, pay attention to avoid weaknesses in production, so hybrids play a greater yield potential. In this study, Kiffinum A (abbreviated as KA), M-40079A (abbreviated as 079A) and M-40081A (abbreviated as 081A) newly introduced and initially appraised by Institute of Crop Research of the International Tropical Semi-aridity in 1981A and 3197A and 1981 Female parent, group with a number of hybrid combinations, determination of the combining ability of the main traits and identification of agronomic traits. The test results are reported below.
