当前,在花生育种上,大家迫切希望能够加快育种进程,早日选出新的优良品种供生产应用,为实现农业的现代化作出贡献。花生是喜温作物,按正常时间(蓬莱地区为4月下旬至5月上旬)播种,因品种不同,生育期为130～170天以上,当地无霜期满足不了一年两代的要求。育种上,要在一年完成两代,习惯上是用温室或南繁。实践证明,这两种办法虽然都能达到当年加代的目的,但是,由于条件的限制和成本过高,不利于大搞群众运动。因此,如何在当地,根据现有条件,采用比较简便的办法,当年杂交,当年加代,一年完成两年的工作,已成为当前开展群众性育种工作急待解决的问题。花生荚果发育及其与积温关系的研究,就是为解决这一问题而提出来的。
At present, on peanut breeding, everyone urgently hopes to speed up the breeding process, select new fine varieties for production and application at an early date, and make contributions to the modernization of agriculture. Peanuts are hi-temperature crops, according to the normal time (Penglai region from late April to early May) sowing, due to different varieties, the growth period of 130 to 170 days or more, the local frost-free period can not meet the requirements of two generations a year. Breeding, to complete two generations a year, it is customary to use the greenhouse or South Fan. Practice has proved that although both of these two approaches can achieve the purpose of adding the generation to the current year, restrictions on the conditions and excessive costs are not conducive to vigorously promoting the mass movement. Therefore, how to use the local conditions according to the existing conditions and adopt a relatively simple method, when the hybridization was carried out in that year, then the work of completing two years in a year has become an urgent issue to be carried out in mass breeding. Peanut pod development and its relationship with accumulated temperature, is to solve this problem put forward.
