7125A是省农科院高粱所1972年以晋713作母本、125B作父本进行有性杂交后,采用早代回交法与3197A连续回转5代,于1974年育成,其保持系是7125B。 7125A生育期135-140天,属中晚熟不育系。株高90厘米左右,穗长22-26厘米,呈紧棒锤穗型,颖壳红色,壳型3级,籽粒白色较透明。在每亩留苗6,000株的情况下,穗重70克左右,千粒重29克,容重720克/升。植株较繁茂,前期叶片上冲,叶色深绿、叶片宽厚、脉色蜡质型、根叶发达。 7125A出圃以来,共测配组合50余个,其中晋中401(7125A×晋辐1号)、晋中402(7125A×晋恢1号)产量比晋杂5号略有提高,适口性、营养品质大有改善。7125A较之3197A具有如下优点: 1.7125A比3197A植株低20厘米左右,
7125A is the Provincial Academy of Agricultural Sorghum Institute in 1972 to 713 as the female parent, 125B as the father of sexual hybrids, the use of early back to back law and 3197A continuous rotation 5 generations, bred in 1974, its maintenance department is 7125B . 7125A growing period of 135-140 days, is a late-maturing sterile line. Plant height of about 90 cm, spike length 22-26 cm, was tight rod hammer panicle, glume shell red, shell type 3, grain white more transparent. In the case of 6,000 strains per mu seedlings, spike weight of about 70 grams, grain weight 29 grams, weighing 720 g / liter. Plant more luxuriant, early leaves on the red, dark green leaves, leaves generous, vein waxy type, developed root and leaves. 7125A since the nursery, a total of more than 50 test combinations, including Jinzhong 401 (7125A × Jinfu 1), Jinzhong 402 (7125A × Jinhui 1) slightly higher than Jinza 5 yield, palatability, nutrition The quality has greatly improved. 7125A has the following advantages over 3197A: 1.7125A is about 20 centimeters lower than 3197A plants,
