(3) it during Controlled irrigation, observes after material to be screened starts drought Stress responses, blade fine day noon wilts,
The drought-enduring material of the selection of starting material drought tolerance, generally this stage, indicates later period resistance to early ageing；It is fine according to weather condition when operation
Its noon, 11:00~14:00 and 15:00~19:00 in afternoon were observed twice；According to expert evidence blade noon wilt and under
The difference of noon recovery situation shows, and selects the red rope label of more drought-enduring single plant system, each segregating population combination selection 200~300
A single plant；Selection gist is that drought-enduring material wilting phenomenon evening occurs, and wilting in afternoon phenomenon restores early；
(4) cotton plant is shown in front of wadding, keeps normal water management, sees and stops pouring water immediately after wadding；
(5) to middle and upper part fruit branch, segregating population can show to start to carry out single plant choosing when obvious leaf function difference cotton plant blow-of-cottons
It selects；Single-plant selection standard are as follows:
A, it is selected in single plant from step (3) and selects；
B, Ye Gongneng is kept preferably in segregating population, and general complete stool falls off blade and yellow leaf number≤complete stool number of blade 25%；
C, 1~4 fruit branch of lower part, it is strong inside to enclose bell knot bell, the first fruit section at bell without missing, and the first and second fruit section Boll probability >=
75%；
D, 5~8 fruit branch of middle part, the first fruit saves Boll probability >=75%, and there can be no the inane fruit branches without knot bell；
E, there can be no the inane fruit branches without knot bell for 1~3 fruit branch of number from the top down at top；
The single plant for meeting above-mentioned five conditions of whole is selected, and be listed record main detection properties and characteristics, and single plant list is received, carries out copying kind
It is detected with fiber quality, selects Single boll weight >=5.3g, single plant ginning outturn >=40%, upper half mean length >=28mm, fracture is than strong
Degree >=28cN/tex, mic value 3.7~5.2；The single plant that F2~F4 low generation filters out by combination or same combination in by property
The similar principle of shape, single plant is classified and is mixed, and next generation mixed planting continues to screen；
(6) low generation separation material is according to above-mentioned steps (1)~step (5) step sizing, until character is stablized；Continue screening
Low generation material, the middle plantation group of step (1) select the mixed grain weight decision received according to the previous generation, expand plantation group as far as possible.
