新(xin)疆農(nong)業科學院李雪(xue)源團隊歷時(shi)10余年選育的(de)突破性(xing)棉花新(xin)品種(zhong)(zhong)(zhong)源棉8號通過了國家農(nong)作物品種(zhong)(zhong)(zhong)審定委員會審定，他們把棉農(nong)理想能(neng)高產、抗蟲害(hai)、早(zao)熟(shu)的(de)棉花種(zhong)(zhong)(zhong)子變成了現實。

新(xin)疆(jiang)作為我(wo)國(guo)最大的(de)棉(mian)(mian)(mian)(mian)花(hua)生產(chan)(chan)(chan)(chan)基地(di)，棉(mian)(mian)(mian)(mian)花(hua)生產(chan)(chan)(chan)(chan)區域(yu)廣闊、環境復雜(za)多(duo)樣(yang)，若(ruo)要實現(xian)產(chan)(chan)(chan)(chan)業(ye)化(hua)(hua)發展，則對棉(mian)(mian)(mian)(mian)花(hua)品(pin)種(zhong)(zhong)(zhong)(zhong)(zhong)要求極高(gao)(gao)。然而目前新(xin)疆(jiang)棉(mian)(mian)(mian)(mian)花(hua)品(pin)種(zhong)(zhong)(zhong)(zhong)(zhong)同(tong)質化(hua)(hua)強，占主導地(di)位的(de)大品(pin)種(zhong)(zhong)(zhong)(zhong)(zhong)少，現(xian)有品(pin)種(zhong)(zhong)(zhong)(zhong)(zhong)要么抗病性(xing)(xing)(xing)不(bu)足，要么品(pin)質不(bu)佳、產(chan)(chan)(chan)(chan)量(liang)不(bu)穩(wen)定(ding)，棉(mian)(mian)(mian)(mian)花(hua)品(pin)種(zhong)(zhong)(zhong)(zhong)(zhong)應用局限性(xing)(xing)(xing)大，影響新(xin)疆(jiang)棉(mian)(mian)(mian)(mian)花(hua)產(chan)(chan)(chan)(chan)業(ye)的(de)高(gao)(gao)質量(liang)發展。新(xin)疆(jiang)農(nong)業(ye)科學院(yuan)研究(jiu)員李雪源(yuan)介紹。在這一背景下(xia)，李雪源(yuan)團隊用了(le)(le)(le)10多(duo)年(nian)的(de)時間，運用南繁加(jia)代(dai)技術，綜(zong)合(he)結構設計育(yu)種(zhong)(zhong)(zhong)(zhong)(zhong)、聚合(he)育(yu)種(zhong)(zhong)(zhong)(zhong)(zhong)和分子標(biao)記選擇育(yu)種(zhong)(zhong)(zhong)(zhong)(zhong)等多(duo)項技術手段，攻克(ke)了(le)(le)(le)棉(mian)(mian)(mian)(mian)花(hua)育(yu)種(zhong)(zhong)(zhong)(zhong)(zhong)中(zhong)產(chan)(chan)(chan)(chan)量(liang)與質量(liang)、產(chan)(chan)(chan)(chan)量(liang)與抗病性(xing)(xing)(xing)、早熟(shu)性(xing)(xing)(xing)與產(chan)(chan)(chan)(chan)量(liang)、早熟(shu)性(xing)(xing)(xing)與機(ji)采性(xing)(xing)(xing)、早熟(shu)性(xing)(xing)(xing)與抗病性(xing)(xing)(xing)等多(duo)項負(fu)相關難題，有效聚合(he)了(le)(le)(le)多(duo)個商業(ye)化(hua)(hua)育(yu)種(zhong)(zhong)(zhong)(zhong)(zhong)性(xing)(xing)(xing)狀指標(biao)，培育(yu)出(chu)了(le)(le)(le)新(xin)品(pin)種(zhong)(zhong)(zhong)(zhong)(zhong)源(yuan)棉(mian)(mian)(mian)(mian)8號，實現(xian)育(yu)種(zhong)(zhong)(zhong)(zhong)(zhong)新(xin)突破，顯著提升了(le)(le)(le)新(xin)疆(jiang)棉(mian)(mian)(mian)(mian)花(hua)育(yu)種(zhong)(zhong)(zhong)(zhong)(zhong)水平。

源棉(mian)8號(hao)(hao)具有(you)廣適性(xing)好(hao)、耐密性(xing)強、集中成熟(shu)性(xing)好(hao)、易管理、鈴大(da)(da)、抗旱耐鹽(yan)堿、耐高(gao)(gao)溫等(deng)特(te)性(xing)，畝(mu)產籽(zi)棉(mian)達(da)到700公斤(jin)左(zuo)(zuo)右，比(bi)一(yi)般高(gao)(gao)產田產量(liang)高(gao)(gao)出200公斤(jin)左(zuo)(zuo)右。此(ci)外(wai)，李雪(xue)源介紹(shao)到，綜(zong)合性(xing)能(neng)優是源棉(mian)8號(hao)(hao)的(de)最(zui)大(da)(da)優勢，也是作為突(tu)破性(xing)新品(pin)(pin)種的(de)最(zui)大(da)(da)特(te)點，該(gai)(gai)品(pin)(pin)種將對促進棉(mian)花均衡增產、提質增效、棉(mian)農(nong)增收(shou)發揮(hui)重(zhong)要(yao)(yao)作用。據(ju)了解(jie)，一(yi)個棉(mian)花品(pin)(pin)種不(bu)僅需要(yao)(yao)滿足(zu)棉(mian)花生產的(de)高(gao)(gao)產、廣適、抗逆、適采需求(qiu)，又要(yao)(yao)滿足(zu)棉(mian)花加工質量(liang)需求(qiu)，還(huan)要(yao)(yao)滿足(zu)紡(fang)織企(qi)業對棉(mian)花質量(liang)的(de)需求(qiu)，則這一(yi)棉(mian)花品(pin)(pin)種就要(yao)(yao)同時具備綜(zong)合性(xing)狀優良(liang)的(de)特(te)點。當前，源棉(mian)8號(hao)(hao)已在阿克蘇(su)、巴州等(deng)地示范推(tui)廣10萬畝(mu)左(zuo)(zuo)右。未來，李雪(xue)源團隊(dui)將圍繞源棉(mian)8號(hao)(hao)品(pin)(pin)種優勢特(te)性(xing)，做好(hao)良(liang)種繁育和良(liang)種良(liang)法配套，更好(hao)發揮(hui)該(gai)(gai)品(pin)(pin)種優良(liang)的(de)生產性(xing)能(neng)潛力，同時做好(hao)示范推(tui)廣。
