Description
Technical field
The invention belongs to the authentication method of the identification and selection in a kind of wheat breeding, particularly a kind of cold type wheat.
Background technology
By measuring the temperature of wheat population, individual plant, it is divided into cold type wheat and warm type wheat, make the evaluation that keeps cold type wheat, eliminates warm type wheat then and select (the patent No.: ZL95104974.7).Because cold type wheat has higher metaboilic level, significantly the premature senescence resistance ability and to adverse circumstance than strong adaptability, be beneficial to very much high yield, the stable yields of wheat, thereby, in wheat breeding, find the cold type wheat material as early as possible, select the cold type wheat offspring, identify the cold type wheat strain and kind is faster for cold type wheat, move towards more on a large scale to produce crucial meaning is just arranged.The inventor finds in research for many years, outside cold type wheat and warm type wheat, also has a class canopy surface temperature osculant wheat, their canopy surface temperature tool polymorphism, be the canopy surface temperature performance that some time can occur cold type wheat, the canopy surface temperature performance or the performance of other more complicated canopy surface temperature of warm type wheat then can appear in some time.Because the canopy surface temperature state in each time of osculant wheat is not quite similar, be full of variety, thereby, just draw a conclusion if only measure according to the canopy surface temperature of 1-2, just might be cold type wheat (Zhang Songwu, Wang Changfa, Feng Baili, a guest, Hao Yanbin to some osculant wheat erroneous judgements, the properties and characteristics of canopy surface temperature polymorphism wheat, Acta Ecologica Sinica 22 (9) 1414-1419 pages or leaves).Hence one can see that, selects the cold type wheat required time longer with the authentication method of measuring wheat population, individual plant temperature, at least also got 3 years.The objective of the invention is to seek a kind of authentication method of cold type wheat more fast and accurately.
Summary of the invention
The present invention is achieved in that at first will be by measuring wheat population, 3 cold type wheats that the authentication method of individual plant temperature is selected are as the standard wheat, then at booting initial stage of wheat, the heading initial stage, come into bloom, the milking maturity initial stage, the dough initial stage and the early dough stage 6 breeding times in observation, record standard wheat and quilt are identified the green number of blade of wheat, compare at last: all green numbers of blade of wheat of being identified all fell in standard wheat corresponding breeding time of the green number of blade excursion or above its upper limit 6 breeding times, then be accredited as cold type wheat, otherwise be accredited as non-cold type wheat.Its concrete steps are:
A. 3 cold type wheats will selecting by the authentication method of measuring wheat population, individual plant temperature are as the standard wheat;
B. standard wheat in the steps A and quilt are identified that wheat is sowed at the field by the method point of wheat breed comparative test, each wheat is planted 3 row at least in each repeats;
C. observe respectively, put down in writing each wheat of being planted among the step B at booting initial stage, heading initial stage, come into bloom, milking maturity initial stage, dough initial stage and the early dough stage these 6 breeding times the green number of blade;
D. each wheat to gained among the step C carries out arithmetric mean respectively in the green number of blade of 6 breeding times, can get the standard wheat and be identified wheat each breeding time of the average green number of blade separately;
E. the average green number of blade with step D gained standard wheat is a foundation, the standard green number of blade excursion that maximum by getting each breeding time and minimum are determined 6 breeding times, then step D gained is identified that wheat each breeding time of the average green number of blade separately compares with it, if being identified the average green blade number average of wheat in each breeding time falls in corresponding breeding time of the standard green number of blade excursion or surpasses its upper limit, just can draw the expert's conclusion that this wheat is a cold type wheat, if the average green number of blade that quilt evaluation wheat has 1 or 1 above breeding time just draws the expert's conclusion that this wheat is non-cold type wheat under the lower limit of standard green number of blade excursion.
When observing, putting down in writing the green number of blade of wheat respectively in step C, each wheat, each repeats to select at random more than 10 or 10 long vaned single stem; The green area of wheat leaf blade account for the whole blade area 30% or be considered as 1 green blade greater than 30%; Be the initial stage of each breeding time the period of observing, put down in writing the green number of blade of each wheat, i.e. day beginning of each breeding time or the 2nd day.
Advantage of the present invention is: the evaluation speed of cold type wheat is obviously accelerated, and only needs just can reach a conclusion in 1 year, and method is simple, and the accuracy rate height is suitable for promoting, using more.
Embodiment
Identify that with 3 cold type wheats and 13 quilts the wheat point is sowed at the field in October, 2002, and whole test district's group is at random arranged, and repeats 3 times, every sub-district 5 row, the long 1.5m of row, line-spacing 0.25m, spacing in the rows 0.03m, the requirement by the wheat breed comparative test during it grows is managed.
The day begin to observe respectively, to put down in writing 3 cold type wheats and 13 green numbers of blade of being identified wheats from the wheat booting beginning, will be when observation, record, each repeats to get at random 10 stems to each wheat, 3 are repeated to get altogether 30 stems.The standard of green blade is: the green area of every blade account for the whole blade area 30% or be considered as 1 green blade greater than 30%.Through heading beginning day, the beginning day of blooming, milking maturity beginning day, dough beginning day and day wax ripeness beginning totally 6 breeding times, the record of the green number of blade finishes.
With each wheat the green number of blade of each beginning period of growth average respectively obtain each wheat in each beginning period of growth average green number of blade separately.3 cold type wheats as the standard wheat, are determined standard green number of blade excursion (seeing Table 1) with its average green number of blade at each beginning period of growth by getting maximum and minimum.Then the average green number of blade of certified 13 wheats is compared with it one by one, consequently: identified in the wheat at 13, have only the average green numbers of blade of 439 each breeding time all to fall in corresponding breeding time of the standard green number of blade excursion, be the expert's conclusion of cold type wheat so can make 439; And other 12 quilts are identified in the wheat, 953 and ZN1 and 84G6 arranged 1 breeding time, Z97 and Yanshi have 2 breeding times for No. 9, TU2 and NR9405 have 3 breeding times, the NC332 and the short rich average green number of blade that arranged 4 breeding times for No. 3 are in corresponding breeding time standard green number of blade excursion, remaining Mianyang 26, the average green number of blade of merchant 6 breeding times of 188 and 9430 these 3 wheats is all under the lower limit of corresponding breeding time of standard green number of blade excursion, can draw these 12 quilts thus and identify that wheat is the expert's conclusion of non-cold type wheat, its rate of accuracy reached 100% (seeing Table 2).
2002-2003 and 2003-2004 these 2 wheat growth seasons, adopt method of the present invention to the mensuration that 12 wheats are tested, 43 kinds have been carried out 162 product time, wherein there are 154 product time accurate, rate of accuracy reached 95.06%.
