1978年前我省引种田菁后,肯定了田菁具有培肥土壤和改良盐碱的良好作用,但种源要由外省调入。选育能在本省成熟的田菁品种(系),成为一个较为迫切的问题。为此,我们在1976—1978年间进行了田菁早熟株系选育试验。首先在北方各省引种了16个田菁品系,1976—1977年株选选出了36个较早熟单株,1978年又从中筛选出3个较早熟的田菁株系77—02、77—08 及77—31。1979年与辽宁省大洼田菁原始材料进行比较试验,证明比原始材料确实具有不同的早熟特性。1980年在省内西部地区和吉林省大安、农安县以及内蒙巴盟农科所等地进行了异地多点鉴定,重点观察各株系的成熟性,进一步证明了三个株系中77—02是一个较早熟的新株系。
Before 1978, after introduction of Sesbania in our province, we affirmed that Sesbania has a good effect of fertilizing the soil and improving saline-alkali, but the provenance should be transferred from other provinces. Breeding Tianjing varieties that can mature in this province has become a more urgent issue. To this end, we conducted in the period of 1976-1978 Triticum aestivum line breeding test. Sixteen strains of Sesbania were first introduced in the northern provinces. Thirty-six older plants were selected from 1976 to 1977, and three more mature Sesbania strains 77-02 and 77-08 And 77 - 31. In 1979, the comparative experiments with the original materials of the Daphniphyllum in Liaoning Province showed that they had different precocious characteristics than the original materials. In 1980 in the western region of the province and the Da’an, Nong’an County, Jilin Province, as well as Inner Mongolia Bama agricultural stations and other places conducted a multi-site identification, focusing on the observation of the maturity of each strain, further evidence of the three strains of 77-02 Is a more familiar new strains.
