Embodiment 1

[0011] The wild kenaf species H040 was used as the female parent, and the UG93 cytoplasmic male sterile maintainer line "Yuefeng 1 B" (see: Example 3 of National Invention Patent ZL200510019454.4) was used as the male parent, and the method of saturated backcrossing was adopted. , H040 cytoplasmic male sterile line H1A and its maintainer line H1B were bred.

Embodiment 2

[0013] The H040 cytoplasmic male sterile line H2A and its maintainer line were bred with the wild kenaf species H040 as the female parent and the conventional cultivated kenaf species Jinguang Wuthorn (introduced by Fujian Agriculture and Forestry University) as the male parent by means of saturated backcrossing. H2B.

Embodiment 3

[0015] F hybridization with kenaf wild species H040×Yuefeng 1 B 1 H040 cytoplasmic male sterile line H3A and maintainer line H3B were bred by using kenaf cultivar Fuhong 3 as male parent and saturated backcross method.

[0016] Example 3:

[0017] Hybrid F with kenaf wild species H040×Jinguang thornless 1 H0403 cytoplasmic male sterile line H4A and maintainer line H4B were bred by using kenaf cultivar No. 917 as male parent and saturated backcross method.

Abstract

The invention relates to a method for breeding kenaf H040 cytoplasmic male sterile line, and belongs to the technical field of breeding of crop male sterile lines. The method takes kenaf wild species H040 or filial generation inherited with cytoplasm of the kenaf wild species H040 as female parent, and takes UG 93 cytoplasmic male sterile maintainer line or kenaf common culture variety as male parent; the female parent and the male parent carry out saturated backcross; the H040 cytoplasmic male sterile line, which is similar to the male parent and is orderly and consistent and exhibits male sterility, is selected and bred; and the backcross female parent is the male sterile maintainer line. The method provides new source of the cytoplasm for the breeding of the kenaf male sterile line, and can combine hybridized combination with comparative advantages.

Description

Technical field: [0001] The invention relates to a breeding method, in particular to a method for selecting a cytoplasmic male sterile line of kenaf. Background technique: [0002] Kenaf, also known as "kenaf", is an annual bast fiber crop of the Malvaceae Hibiscus genus. Because kenaf is cultivated for the purpose of harvesting bast fibers or stems, the heterosis rate is as high as 35% to 40%. The utilization of kenaf heterosis has long been the main goal of kenaf breeding at home and abroad. After years of research, the Cannabis Research Institute of the Chinese Academy of Agricultural Sciences invented the chemical male-killing hybrid seed production method of kenaf and applied it in kenaf breeding. However, because kenaf is an infinite inflorescence, multiple application of pesticides is required, and insect pollination is affected after application, so artificial pollination is required. In order to save costs, only to promote F in production 2 generation (hybrid sec...
