Problems solved by technology

[0003] At present, drought resistance, barren resistance, disease resistance and other stress resistance of sugarcane varieties need to be improved, and variety adaptability and perennial root performance are also relatively poor. Improve the drought resistance, barren resistance, disease resistance and other stress resistance of sugarcane varieties to enhance variety adaptability The research and utilization of sugarcane wild germplasm resources have become the focus and hotspot of sugarcane genetics and breeding.

Embodiment 1

[0015] Utilization of Manyao Gaeshoumi in Yunnan and Mengla Gaeshoumi in Yunnan:

[0016] Firstly, use POJ3016×Yunnan Manyao to cut hand secrets→Yuncut F 1 80-189, the second step is to use cloud cutting F 1 80-189×Yunnan Mengla Cutshoumi→Yuncut F 1 08-11, Yuncut F 1 08-11 The output of cane stalks exceeded that of Yuncao F 1 8-10% of 80-189.

Embodiment 2

[0018] Utilization of Yunnan Manyao Gaeshoumi and Yunnan Xishuangbanna Gaeshoumi:

[0019] Firstly, use POJ3016×Yunnan Manyao to cut hand secrets→Yuncut F 1 80-189, Yuncut F 1 80-189 inbred → Yuncut F 1 91-2868; The second step is to use the cloud cut F 1 91-2868×Yunnan Xishuangbanna cut hand secret→Yuncut F 1 97-105, Yuncut F 1 Effective stem count of 97-105 exceeds Yuncut F 1 10-14% of 80-189.

Abstract

The invention relates to a utilization method of hybridization between wild consanguinity F1 and wild species of sugarcane. An F1 generation containing wild consanguinity is obtained by hybridizing a cultivation type tropical species or a production species as a female parent with an excellent wild species; and then, a filial generation containing consanguinity of two excellent wild species is obtained by hybridizing the F1 generation containing the wild consanguinity as a female parent with another excellent wild species. According to the utilization method disclosed by the invention, the wild consanguinity F1 is hybridized with the wild species, chromosomes are inherited in an n+n manner, the stress tolerance properties, such as drought resistance, barren tolerance and disease resistance of the wild consanguinity are further enhanced, a novel breeding material is provided for improving sugarcane products, the stress resistance, the adaptability and the perennial root property of sugarcane varieties are favorably improved, the breeding efficiency is favorably improved, and therefore the utilization method is a novel path for hybridization utilization of wild germplasm resources of the sugarcane.

Description

technical field [0001] The invention relates to the technical field of genetic breeding of sugarcane germplasm resources, in particular to a method for utilizing sugarcane wild bloodline F1 hybridized with wild species. Background technique [0002] Sugarcane variety improvement is the core technology to promote the development of the sugar industry. Since the 1920s, the Dutch used the wild resources of sugarcane in Java to crossbreed with tropical species and bred POJ2878, POJ2875 and other sugarcane varieties that are popular in the world. , Selected and bred world famous production varieties such as CO290, CO280, NCO310, saved and promoted the development of the sugar industry. So far, most of the sugarcane varieties bred in the future are descendants of POJ and CO series. [0003] At present, drought resistance, barren resistance, disease resistance and other stress resistance of sugarcane varieties need to be improved, and variety adaptability and perennial root perfo...
