In 2021,Xinjiang's cotton output was 5.129 million t,accounting for 89.50%of China's total.The autonomous region produces high-quality long-staple cotton,natural colored cotton,fine-staple cotton(upland cotton),organic cotton,etc.The southern Xinjiang cotton area is one of the three major long-staple cotton(island cotton)producing regions in the world.This paper introduced the history of cotton planting and breeding in Xinjiang from the aspects of cultural relics records,history of entering Xinjiang,historical achievements of breeding and breeding leaders.We studied the intellectual property protection of cotton breeding in the autonomous region from the aspects of biological genetic resources,invention patents,utility model patents and new plant varieties,analyzed the six main problems existing in cotton breeding and its intellectual property protection,and discussed the tactics for cotton breeding and its intellectual property protection in Xinjiang under the strategy of strengthening the country with intellectual property.Eight suggestions in response to the Xinjiang cotton incident were also put forward,including establishing a Xinjiang national cotton germplasm nursery,protecting biological genetic resources,and strengthening the protection of creative intellectual property rights in the field of breeding to escort technological innovation in the cotton seed industry.

Results The population had large variations for lint yield,fibre properties,predicted yarn properties,and composite fibre quality values.Lint yield with all fibre quality traits was not correlated.When the selection was conducted first to keep those with improved fibre quality,and followed for high yields,a large proportion in the resultant populations was the same between selections based on cottonspec predicted yarn quality and HVI-measured fibre properties.They both exceeded the selection based on FQI and Background The approach of directly testing yarn quality to define fibre quality breeding objectives and progress the selection is attractive but difficult when considering the need for time and labour.The question remains whether yarn prediction tools from textile research can serve as an alternative.In this study,using a dataset from three seasons of field testing recombinant inbred line population,cottonspec,a software developed by the Commonwealth Scientific and Industrial Research Organisation(CSIRO)for predicting ring spun yarn quality from fibre properties measured by High Volume Instrument(HVI),was used to select improved fibre quality and lint yield in the population.The population was derived from an advanced generation inter-crossing of four CSIRO conventional commercial varieties.The cottonspec program was able to provide an integrated index of the fibre qualities affecting yarn properties.That was compared with selection based on HVI-measured fibre properties,and two composite fibre quality variables,namely,fibre quality index(FQI),and premium and discount(PD)points.The latter represents the net points of fibre length,strength,and micronaire based on the Premiums and Discounts Schedule used in the market while modified by the inclusion of elongation.PD points.Conclusions The population contained elite segregants with improved yield and fibre properties,and cottonspec predicted yarn quality is useful to effectively capture these elites.There is a need to further develop yarn quality prediction too

The’Target Trait breeding Gene Bank’（TTBGB）was constructed based on mixed selection,and the offsprings of distant hybridization had been improved through hybridization,backcross and multiple hybridization of G.hirsutum,G.barbadense and G.thurberi.In past more than 40years,493lines from inter-specific hybridization has been developed and evaluated in term of yield,lint,fiber quality and Verticillium Wilt resistance.The results show that lint percentages of 84of the 493lines are close to 40%;four of the 493lines have similar fiber quality as G.barbadense;four of the 493lines are highly resistant to Verticillium Wilt.In addition,the inheritance of Verticillium Wilt resistance of introgressed lines from interspecific hybridization had been analyzed. The results indicated that the genotype of Verticillium Wilt resistance might be controlled by two additive genes and one dominant gene.These two additive genes play a major role in Verticillium Wilt resistance in comparison with the dominant gene.More over,nine new cotton varieties had been recognized and registered through TTBGB project by National Crop Breed Committee during the 11th National Five-Year Plan of China.It is about 13.2%of total new registered cotton varieties in The Yellow River Region during this period.cotton variety,Ji228,has the high quality of fiber with length 31.8mm,strength 32cN·tex-1,and micronaire 4.6;and Ji2000has length 31.7 mm,strength 30.8cN·tex-1 and micronaire 4.3.These two cotton varieties are among the best fiber quality of 18conventional cotton varieties and 12cotton varieties which can be intercropped with wheat.cotton variety,Ji985,is one of the conventional cotton varieties,which has good fiber quality,strong Fusarium and Verticillium Wilt resistance and high yield.It has been as the reference for Hebei Regional Test of cotton Varieties since 2008.cotton varieties,Ji228and Ji985,had been listed as national key cotton varieties for the popularization in Hebei,Shandong,Henan provinces since 2008.However,there are some areas,which need
