新疆農業(ye)科學院李雪(xue)源團隊(dui)歷時(shi)10余年選(xuan)育的突破性棉花新品(pin)種(zhong)源棉8號通(tong)過了(le)國家農作物(wu)品(pin)種(zhong)審定委員會審定，他們把棉農理想能高產(chan)、抗蟲害、早熟(shu)的棉花種(zhong)子變(bian)成了(le)現(xian)實。

新(xin)(xin)疆作為我國最(zui)大(da)(da)(da)的(de)棉(mian)(mian)花(hua)生產(chan)(chan)基地，棉(mian)(mian)花(hua)生產(chan)(chan)區域廣闊、環境(jing)復雜多樣，若要實現(xian)產(chan)(chan)業(ye)化發展(zhan)，則對棉(mian)(mian)花(hua)品(pin)(pin)種(zhong)(zhong)(zhong)(zhong)要求極高(gao)。然(ran)而(er)目前(qian)新(xin)(xin)疆棉(mian)(mian)花(hua)品(pin)(pin)種(zhong)(zhong)(zhong)(zhong)同質化強，占主導地位的(de)大(da)(da)(da)品(pin)(pin)種(zhong)(zhong)(zhong)(zhong)少(shao)，現(xian)有品(pin)(pin)種(zhong)(zhong)(zhong)(zhong)要么(me)抗病性不(bu)足，要么(me)品(pin)(pin)質不(bu)佳、產(chan)(chan)量不(bu)穩定(ding)，棉(mian)(mian)花(hua)品(pin)(pin)種(zhong)(zhong)(zhong)(zhong)應用局限性大(da)(da)(da)，影(ying)響新(xin)(xin)疆棉(mian)(mian)花(hua)產(chan)(chan)業(ye)的(de)高(gao)質量發展(zhan)。新(xin)(xin)疆農業(ye)科學(xue)院研(yan)究員李雪源(yuan)介紹。在這一(yi)背景下(xia)，李雪源(yuan)團隊用了(le)10多年的(de)時間，運用南繁加代技術，綜(zong)合(he)結構設(she)計育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)、聚合(he)育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)和分(fen)子標(biao)(biao)記選擇育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)等多項技術手段，攻克了(le)棉(mian)(mian)花(hua)育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)中產(chan)(chan)量與(yu)質量、產(chan)(chan)量與(yu)抗病性、早(zao)熟(shu)性與(yu)產(chan)(chan)量、早(zao)熟(shu)性與(yu)機采性、早(zao)熟(shu)性與(yu)抗病性等多項負相(xiang)關難題，有效聚合(he)了(le)多個商業(ye)化育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)性狀指標(biao)(biao)，培育(yu)(yu)出了(le)新(xin)(xin)品(pin)(pin)種(zhong)(zhong)(zhong)(zhong)源(yuan)棉(mian)(mian)8號，實現(xian)育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)新(xin)(xin)突破，顯(xian)著提升(sheng)了(le)新(xin)(xin)疆棉(mian)(mian)花(hua)育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)水(shui)平。

源(yuan)棉(mian)(mian)(mian)8號(hao)具有(you)廣(guang)適(shi)性(xing)好(hao)(hao)、耐(nai)(nai)密性(xing)強、集中成熟性(xing)好(hao)(hao)、易管理、鈴(ling)大(da)、抗(kang)旱耐(nai)(nai)鹽堿、耐(nai)(nai)高溫等(deng)特(te)(te)性(xing)，畝產(chan)(chan)籽棉(mian)(mian)(mian)達(da)到700公(gong)斤左右(you)(you)，比一(yi)般高產(chan)(chan)田產(chan)(chan)量(liang)高出200公(gong)斤左右(you)(you)。此外(wai)，李(li)雪源(yuan)介(jie)紹到，綜合(he)性(xing)能優(you)是(shi)源(yuan)棉(mian)(mian)(mian)8號(hao)的(de)最(zui)大(da)優(you)勢，也是(shi)作為突破性(xing)新品(pin)(pin)種(zhong)(zhong)的(de)最(zui)大(da)特(te)(te)點，該品(pin)(pin)種(zhong)(zhong)將(jiang)對促進棉(mian)(mian)(mian)花(hua)均衡增(zeng)產(chan)(chan)、提(ti)質(zhi)增(zeng)效(xiao)、棉(mian)(mian)(mian)農增(zeng)收發(fa)揮重要(yao)(yao)作用。據了(le)解，一(yi)個棉(mian)(mian)(mian)花(hua)品(pin)(pin)種(zhong)(zhong)不僅需要(yao)(yao)滿足棉(mian)(mian)(mian)花(hua)生產(chan)(chan)的(de)高產(chan)(chan)、廣(guang)適(shi)、抗(kang)逆、適(shi)采(cai)需求，又要(yao)(yao)滿足棉(mian)(mian)(mian)花(hua)加(jia)工質(zhi)量(liang)需求，還要(yao)(yao)滿足紡織(zhi)企業對棉(mian)(mian)(mian)花(hua)質(zhi)量(liang)的(de)需求，則這一(yi)棉(mian)(mian)(mian)花(hua)品(pin)(pin)種(zhong)(zhong)就(jiu)要(yao)(yao)同時(shi)具備綜合(he)性(xing)狀(zhuang)優(you)良(liang)的(de)特(te)(te)點。當(dang)前(qian)，源(yuan)棉(mian)(mian)(mian)8號(hao)已在阿克蘇(su)、巴(ba)州(zhou)等(deng)地示范推廣(guang)10萬畝左右(you)(you)。未來，李(li)雪源(yuan)團隊(dui)將(jiang)圍繞(rao)源(yuan)棉(mian)(mian)(mian)8號(hao)品(pin)(pin)種(zhong)(zhong)優(you)勢特(te)(te)性(xing)，做(zuo)好(hao)(hao)良(liang)種(zhong)(zhong)繁育和良(liang)種(zhong)(zhong)良(liang)法配套，更好(hao)(hao)發(fa)揮該品(pin)(pin)種(zhong)(zhong)優(you)良(liang)的(de)生產(chan)(chan)性(xing)能潛力，同時(shi)做(zuo)好(hao)(hao)示范推廣(guang)。
