Abstract

The invention discloses a breeding method of a high-yield and high-starch brewed sorghum hybrid. HV45A which is used as a female parent and YNl41R as a male parent are bred by hybrid combination. The hybrid parent HV45A uses 406B*ICS-34B as a basis material, and the hybrid parent and Liao 5B are compounded into hybrids through artificial sexual hybridization. After six generations of field breeding in the South and the North, the northern plant height is stabilized at 90 centimeters, and the plant is not isolated any more; the plant and 0427A are subjected to backcross breeding in Hainan, and the sterility is up to 100% by observation in the North and the South; and then the hybrid is formed by successive backcross breeding, and named as HV45A by a northern area code. A restorer line YNl41R is formed by taking a primer S02lR as artificial castrated female parent and dwarf 4 as a male parent, artificial sexual hybridization and continuous breeding of multiple generations in the North and the South. Through the hybridization way, the high-yield and high-starch brewed sorghum hybrid No. Ji hybrid 355 can be obtained.

Description

The high starch of a kind of high yield is brewageed the selection of sorghum hybrid

Technical field

The invention belongs to crop hybrid superiority and utilize technical field, relate in particular to the selection that a kind of high yield, high starch are brewageed sorghum hybrid.

Background technology

Sorghum grass family sorghum, annual herb.The property happiness temperature, drought resisting, waterlogging is divided into 4 types according to purposes and the different of inflorescence, seed form: grain sorghum, sugar are with Chinese sorghum, forage sorghum and broom sorghum.It is wider in China's cultivation to compare grain sorghum (edible, processing), serves as maximum with the various places, northeast.Grain was edible in the past, was the northern people's staple food always, the Along with people's growth in the living standard, and it is main that the purposes of Chinese sorghum changes into wine brewing gradually, present being used to more than 95% brewages, and makes wine (liquor made from sorghum), makes vinegar.In recent years, the change of Along with people's diet structure, sorghum rice is returned dining table again as a kind of distinctive coarse food grain.Sorghum rice has the good reputation of " essences of five cereals ", " length of hundred paddy " from ancient times, and not only be of high nutritive value, and can be used as medicine, various disease conditions such as treatment indigestion, Chinese sorghum food is especially to the diabetic advantageous particularly.Because drought-enduring, waterlogging, the impoverishment tolerant of Chinese sorghum can be planted on the soil away from industrial pollution, thereby produce organic sorghum rice.

The high starch Chinese sorghum of high yield is mainly used in brewages, and is the good raw material of brewageing high quality liquor.As everyone knows, the famous liquor of China all is that primary raw material is brewageed with the Chinese sorghum.The liquor distillation yield of brewageing with high starch Chinese sorghum is high, the wine quality better.Along with the increase of high starch Chinese sorghum market demand, China's grain sorghum area is steadily increasing.This mainly come from Chinese sorghum as drinks process raw material, the demand of forage compounding raw material is increasing.In recent years owing to the frequent generation of drought, floods, especially northern shortage of water resources is outstanding day by day, and the minimizing of ploughing, the increase of population, and people more and more pay attention to stablizing the Chinese sorghum grain-production.Therefore, Chinese sorghum not only has the value of its existence as drought resisting, waterlogging-resistant high and stable yields crop, has also shown the economic benefits of high added value.The Chinese sorghum plantation continues to shift to the saline and alkaline area of arid.Be to ensure grain security, realize the adjustment of pattern of farming, relatively poor relatively in natural conditions, working condition is general, drought, floods take place frequently and saline and alkaline easy waterlogging district, should suitably enlarge the Chinese sorghum plantation.On sorghum variety was selected, key will be given prominence to " excellent " word.So the Chinese sorghum breeding objective is stressed high-quality, high yield and how anti-.

Summary of the invention

The present invention is in order to provide a kind of high yield, high starch to brewage the selection of sorghum hybrid.

The object of the invention can be realized through following technical proposal:

The seed selection that a kind of high yield, high starch are brewageed sorghum hybrid is maternal with HV45A, forms for the male parent assembly with YN141R.(this strain of father and mother is the ripe kind of commercialization of prior art, can buy in the Jilin Academy of Agricultural Science to obtain).

HV45A is to be basic material with 406B * ICS-34B, through artificial sexual hybridization, and the multiple cross offspring who does with distant 5B.Through 6 southern and northern field breeding of generation, northern plant height is stabilized in 90 centimetres, no longer separates, and carries out the southern and northern observation of backcross transformation sterile degree in Hainan with 0427A and reaches 100%, and the continuous backcross seed selection forms then, and naming with northern area code is HV45A.

Recovery be YN141R draw beyond being S021R do artificial castrate maternal, short four being male parent, through artificial sexual hybridization and southern and northern many from generation to generation continuously seed selections form.Carry out restorative mensuration with a plurality of conventional male sterile lines, performance restorability in its crossbreed north is stable, recovery rate 100%, and hybrid vigour is strong, and therefore will recover is that to name with northern area code be YN141R.Be used as and hybridize the assembly male parent in a large number

Through crossbreed observation and the test of product ratio, select field performance high yield, stable yields, the Ji that exterior quality is good is mixed No. 355.

Lucky assorted No. 355 is middle seasonal strain, emerges to ripe 118-123 days, needs >=10 ℃ active accumulated temperature 2550-2700 ℃.Seedling is green, plant height 175.6cm, 18 leaves, spike length 28.7cm, the heavy 115.4g of fringe grain; In tight fringe, tubular, single grain number per spike 3500-4000 grain, thousand kernel weight 28.8g, vitreousness 30%; Shell rate 6.3%, the red grain of red shell, seed is circular, and unit weight 758g/l restoratively reaches 100%.Grain protein content 8.78%, content of starch 76.11%, fat 3.40%, tannin content 1.09%.Comprehensive resistance is good, and is resistant to lodging, high disease-resistanting leaf spot, middle anti-head-smut, anti-aphid, anti-snout moth's larva.

Embodiment

Key seed selection of the present invention is exactly through selecting good basic material to be the basic parent of hybridization; Select in the orientation of parent and crossbreed; Stress to form the branch stalk seed selection of output key factor, therefore shortened Chinese sorghum fringe departmental level branch stalk length, increased by two, three grades of branch stalk numbers; It is heavy to have increased single grain number per spike and single fringe grain, is gross output thereby increase the Chinese sorghum population yield.This kind is successfully passed through Jilin Province's variety of crops evaluation, meets Ministry of Agriculture's new varieties evaluation requirement, and the commercialization prospect is arranged.

The most grain number per spike of Chinese sorghum in the past is at the 3000-3500 grain; List fringe grain focuses on about the 85-100 gram, and takes to shorten one-level branch stalk length, increases lucky the mixing No. 355 of the high starch Chinese sorghum of high yield that two, three grades of branches stalk counting methods are bred; Single grain number per spike 3500-4000 grain, single fringe grain weighs about 115.4 grams.Identify and artificial evaluation that through natural resistance lucky assorted No. 355 comprehensive resistances are good, resistant to lodging, high disease-resistanting leaf spot, middle anti-head-smut, anti-aphid, anti-snout moth's larva, not early ageing of seed.Through the unit weight test, unit weight 758g/l, performance quality better.
