Embodiment 1

[0020] "Kebanjin" from a farm in Heishan County, Liaoning Province was used to find a single female plant through multiple generations of selfing, and after multiple generations of flower-induced selfing, a castor female line "84-1" was bred as the female parent, and the capsule was thornless and large-grained The castor inbred line "No Tattoo" was used as the male parent, and the first castor hybrid in my country "Zi Castor No. 1" was selected, which was approved by the Shandong Provincial Variety Approval Committee in 1996. More than 300,000 mu have been promoted, which is 36-70% higher than that of farm species.

Embodiment 2

[0022] The female line "9041" of large spike type castor was used as the female parent and the inbred line 893 of castor bean without capsules was used as the male parent, and the first-generation hybrid "Zi Castor No. 2" was successfully combined. It passed through Shandong Province in 2000. Approved by the Variety Approval Committee, it became the first high-fat variety in my country, with a promotion area of ​​400,000 mu. Compared with Jinbi No. 2, the yield increased by more than 10%.

Embodiment 3

[0024] The female line "9041" with large spike type was used as the female parent, and the high-yield and high-resistance castor inbred line "Tai 101" bred from externally introduced castor germplasm resources was used as the male parent. "The first generation of high-yield hybrids, with an increase of more than 20% compared with "Jinbi 2". From 2002 to 2005, it passed the approval of Ningxia and Xinjiang Yili Prefecture Variety Approval Committees, and became the first choice for updating and upgrading varieties in the country.

Abstract

The invention provides a two-line hybrid ricin seed production method, which belongs to the heterosis utilization field. It includes: ricin female line selecting, breeding, two-line hybrid seed cross-pairing and two-line hybrid seed producing. The invention overcomes the problem of artificial extracting amphoteric plants during blooming period in the process of amphoteric female line (that is about 50% of the plants are female, 50% are amphoteric) hybrid seed production, simplifies ricin hybrid producing procedures and realizes two-line single cross seeds production. At the same time the invention has the merits of simple seed producing method, high seed purity, big F1 heterosis, high yield production, good uniformity, good quality and so on. The method is suitable for wide spread.

Description

technical field [0001] The invention discloses a castor-oil two-line method hybrid seed production method, relates to the production of castor-oil hybrid seeds, and belongs to the field of crop heterosis utilization. Background technique [0002] Utilization of castor heterosis is the most significant technical measure to increase yield and benefit. It has been the goal pursued by castor breeding work in various countries for a long time. [0003] The core technology of the use of castor heterosis is the selection and breeding of the female parent "castor bean female line" for castor hybrid seed production and the method of preparing the first generation of hybrid seeds. According to reports, since the United States began in 1950, the former Soviet Union, India, France, and Brazil have all carried out a large number of studies and experiments. But there is no good solution to the multiplication and hybrid seed production technology methods of castor bean female lines all t...
