新(xin)疆農(nong)(nong)業科學院李雪源團隊歷(li)時10余年選育的突(tu)破(po)性棉花(hua)新(xin)品種源棉8號通過了國家(jia)農(nong)(nong)作物品種審定委員會(hui)審定，他們把棉農(nong)(nong)理想能高產、抗蟲害、早熟的棉花(hua)種子變(bian)成了現實(shi)。

新(xin)(xin)(xin)疆(jiang)(jiang)(jiang)作為我國最大(da)的(de)棉(mian)花生產(chan)(chan)(chan)(chan)(chan)基(ji)地，棉(mian)花生產(chan)(chan)(chan)(chan)(chan)區域廣闊(kuo)、環境復雜多(duo)(duo)樣，若要實現(xian)產(chan)(chan)(chan)(chan)(chan)業化(hua)發展，則對(dui)棉(mian)花品(pin)種(zhong)(zhong)要求極高(gao)。然而目前新(xin)(xin)(xin)疆(jiang)(jiang)(jiang)棉(mian)花品(pin)種(zhong)(zhong)同質化(hua)強，占主導地位的(de)大(da)品(pin)種(zhong)(zhong)少，現(xian)有(you)(you)品(pin)種(zhong)(zhong)要么抗(kang)(kang)病性(xing)(xing)(xing)(xing)不(bu)足，要么品(pin)質不(bu)佳(jia)、產(chan)(chan)(chan)(chan)(chan)量(liang)(liang)不(bu)穩定(ding)，棉(mian)花品(pin)種(zhong)(zhong)應用局(ju)限性(xing)(xing)(xing)(xing)大(da)，影響(xiang)新(xin)(xin)(xin)疆(jiang)(jiang)(jiang)棉(mian)花產(chan)(chan)(chan)(chan)(chan)業的(de)高(gao)質量(liang)(liang)發展。新(xin)(xin)(xin)疆(jiang)(jiang)(jiang)農業科(ke)學院研究員李(li)雪源(yuan)介紹。在這一背景下，李(li)雪源(yuan)團隊用了10多(duo)(duo)年的(de)時間，運用南繁加代技術，綜合(he)結構設計育(yu)(yu)種(zhong)(zhong)、聚合(he)育(yu)(yu)種(zhong)(zhong)和(he)分子(zi)標記選(xuan)擇育(yu)(yu)種(zhong)(zhong)等多(duo)(duo)項技術手段，攻克了棉(mian)花育(yu)(yu)種(zhong)(zhong)中產(chan)(chan)(chan)(chan)(chan)量(liang)(liang)與(yu)(yu)質量(liang)(liang)、產(chan)(chan)(chan)(chan)(chan)量(liang)(liang)與(yu)(yu)抗(kang)(kang)病性(xing)(xing)(xing)(xing)、早熟性(xing)(xing)(xing)(xing)與(yu)(yu)產(chan)(chan)(chan)(chan)(chan)量(liang)(liang)、早熟性(xing)(xing)(xing)(xing)與(yu)(yu)機采性(xing)(xing)(xing)(xing)、早熟性(xing)(xing)(xing)(xing)與(yu)(yu)抗(kang)(kang)病性(xing)(xing)(xing)(xing)等多(duo)(duo)項負(fu)相(xiang)關(guan)難題，有(you)(you)效聚合(he)了多(duo)(duo)個(ge)商(shang)業化(hua)育(yu)(yu)種(zhong)(zhong)性(xing)(xing)(xing)(xing)狀指(zhi)標，培育(yu)(yu)出了新(xin)(xin)(xin)品(pin)種(zhong)(zhong)源(yuan)棉(mian)8號(hao)，實現(xian)育(yu)(yu)種(zhong)(zhong)新(xin)(xin)(xin)突(tu)破，顯著提升了新(xin)(xin)(xin)疆(jiang)(jiang)(jiang)棉(mian)花育(yu)(yu)種(zhong)(zhong)水平。

源(yuan)(yuan)(yuan)棉(mian)(mian)8號(hao)具(ju)有廣(guang)(guang)適性(xing)(xing)(xing)好、耐密(mi)性(xing)(xing)(xing)強、集中成熟性(xing)(xing)(xing)好、易(yi)管理、鈴(ling)大、抗(kang)旱耐鹽堿(jian)、耐高(gao)(gao)(gao)溫等(deng)(deng)特(te)性(xing)(xing)(xing)，畝產(chan)(chan)籽棉(mian)(mian)達到700公斤(jin)左右，比一(yi)(yi)般高(gao)(gao)(gao)產(chan)(chan)田產(chan)(chan)量高(gao)(gao)(gao)出200公斤(jin)左右。此外(wai)，李(li)雪(xue)源(yuan)(yuan)(yuan)介紹到，綜合性(xing)(xing)(xing)能(neng)優(you)是源(yuan)(yuan)(yuan)棉(mian)(mian)8號(hao)的最大優(you)勢，也是作為(wei)突(tu)破(po)性(xing)(xing)(xing)新(xin)品(pin)種(zhong)(zhong)(zhong)的最大特(te)點(dian)，該(gai)品(pin)種(zhong)(zhong)(zhong)將(jiang)對促進棉(mian)(mian)花均衡增(zeng)產(chan)(chan)、提(ti)質(zhi)增(zeng)效(xiao)、棉(mian)(mian)農增(zeng)收發揮(hui)重(zhong)要(yao)作用。據(ju)了解，一(yi)(yi)個棉(mian)(mian)花品(pin)種(zhong)(zhong)(zhong)不僅(jin)需要(yao)滿足棉(mian)(mian)花生(sheng)產(chan)(chan)的高(gao)(gao)(gao)產(chan)(chan)、廣(guang)(guang)適、抗(kang)逆、適采(cai)需求，又(you)要(yao)滿足棉(mian)(mian)花加工質(zhi)量需求，還要(yao)滿足紡織企業對棉(mian)(mian)花質(zhi)量的需求，則這一(yi)(yi)棉(mian)(mian)花品(pin)種(zhong)(zhong)(zhong)就(jiu)要(yao)同時(shi)具(ju)備綜合性(xing)(xing)(xing)狀優(you)良(liang)的特(te)點(dian)。當前，源(yuan)(yuan)(yuan)棉(mian)(mian)8號(hao)已在阿克(ke)蘇、巴州等(deng)(deng)地示(shi)范推廣(guang)(guang)10萬畝左右。未來，李(li)雪(xue)源(yuan)(yuan)(yuan)團隊(dui)將(jiang)圍繞源(yuan)(yuan)(yuan)棉(mian)(mian)8號(hao)品(pin)種(zhong)(zhong)(zhong)優(you)勢特(te)性(xing)(xing)(xing)，做(zuo)好良(liang)種(zhong)(zhong)(zhong)繁育和良(liang)種(zhong)(zhong)(zhong)良(liang)法配套(tao)，更好發揮(hui)該(gai)品(pin)種(zhong)(zhong)(zhong)優(you)良(liang)的生(sheng)產(chan)(chan)性(xing)(xing)(xing)能(neng)潛(qian)力，同時(shi)做(zuo)好示(shi)范推廣(guang)(guang)。
