新疆(jiang)農(nong)業科學院(yuan)李雪源團隊(dui)歷時10余(yu)年選(xuan)育的突(tu)破性棉花新品種源棉8號通過(guo)了國家農(nong)作物品種審定委員會審定，他們把棉農(nong)理想能高產、抗蟲害(hai)、早熟的棉花種子變成了現(xian)實。

新疆(jiang)(jiang)作為我國(guo)最大(da)的(de)棉(mian)(mian)花(hua)生(sheng)(sheng)產(chan)(chan)(chan)(chan)基地，棉(mian)(mian)花(hua)生(sheng)(sheng)產(chan)(chan)(chan)(chan)區域廣闊、環境(jing)復(fu)雜多(duo)樣(yang)，若要(yao)實現產(chan)(chan)(chan)(chan)業(ye)(ye)化發(fa)展，則(ze)對棉(mian)(mian)花(hua)品(pin)種(zhong)(zhong)(zhong)要(yao)求極高。然而(er)目前新疆(jiang)(jiang)棉(mian)(mian)花(hua)品(pin)種(zhong)(zhong)(zhong)同質(zhi)化強，占主導地位的(de)大(da)品(pin)種(zhong)(zhong)(zhong)少，現有(you)(you)品(pin)種(zhong)(zhong)(zhong)要(yao)么抗(kang)病性(xing)(xing)不足，要(yao)么品(pin)質(zhi)不佳、產(chan)(chan)(chan)(chan)量(liang)不穩(wen)定，棉(mian)(mian)花(hua)品(pin)種(zhong)(zhong)(zhong)應用(yong)局限性(xing)(xing)大(da)，影(ying)響新疆(jiang)(jiang)棉(mian)(mian)花(hua)產(chan)(chan)(chan)(chan)業(ye)(ye)的(de)高質(zhi)量(liang)發(fa)展。新疆(jiang)(jiang)農業(ye)(ye)科學(xue)院(yuan)研究員李(li)(li)雪源(yuan)介紹。在這一背景(jing)下，李(li)(li)雪源(yuan)團隊用(yong)了(le)10多(duo)年的(de)時(shi)間，運用(yong)南(nan)繁(fan)加代技(ji)術，綜合(he)結構設計育(yu)(yu)種(zhong)(zhong)(zhong)、聚合(he)育(yu)(yu)種(zhong)(zhong)(zhong)和分子標(biao)(biao)記選擇育(yu)(yu)種(zhong)(zhong)(zhong)等多(duo)項(xiang)技(ji)術手段，攻(gong)克了(le)棉(mian)(mian)花(hua)育(yu)(yu)種(zhong)(zhong)(zhong)中產(chan)(chan)(chan)(chan)量(liang)與質(zhi)量(liang)、產(chan)(chan)(chan)(chan)量(liang)與抗(kang)病性(xing)(xing)、早(zao)熟性(xing)(xing)與產(chan)(chan)(chan)(chan)量(liang)、早(zao)熟性(xing)(xing)與機采性(xing)(xing)、早(zao)熟性(xing)(xing)與抗(kang)病性(xing)(xing)等多(duo)項(xiang)負相關難題，有(you)(you)效聚合(he)了(le)多(duo)個商(shang)業(ye)(ye)化育(yu)(yu)種(zhong)(zhong)(zhong)性(xing)(xing)狀指標(biao)(biao)，培育(yu)(yu)出(chu)了(le)新品(pin)種(zhong)(zhong)(zhong)源(yuan)棉(mian)(mian)8號，實現育(yu)(yu)種(zhong)(zhong)(zhong)新突破，顯著提升了(le)新疆(jiang)(jiang)棉(mian)(mian)花(hua)育(yu)(yu)種(zhong)(zhong)(zhong)水平。

源(yuan)棉(mian)(mian)(mian)8號具(ju)有廣(guang)適性(xing)(xing)好、耐(nai)(nai)密性(xing)(xing)強、集中成熟性(xing)(xing)好、易管理、鈴大、抗(kang)旱耐(nai)(nai)鹽(yan)堿、耐(nai)(nai)高溫等(deng)特(te)性(xing)(xing)，畝產(chan)籽棉(mian)(mian)(mian)達到700公斤(jin)左(zuo)右，比(bi)一般高產(chan)田(tian)產(chan)量(liang)高出200公斤(jin)左(zuo)右。此外，李(li)雪源(yuan)介(jie)紹(shao)到，綜(zong)合(he)性(xing)(xing)能(neng)優(you)(you)是源(yuan)棉(mian)(mian)(mian)8號的(de)(de)最(zui)大優(you)(you)勢(shi)，也(ye)是作為(wei)突破性(xing)(xing)新品種(zhong)(zhong)的(de)(de)最(zui)大特(te)點，該品種(zhong)(zhong)將對促(cu)進(jin)棉(mian)(mian)(mian)花(hua)均衡增產(chan)、提質增效、棉(mian)(mian)(mian)農增收發(fa)揮重要作用。據(ju)了解，一個棉(mian)(mian)(mian)花(hua)品種(zhong)(zhong)不(bu)僅需要滿(man)(man)足棉(mian)(mian)(mian)花(hua)生(sheng)產(chan)的(de)(de)高產(chan)、廣(guang)適、抗(kang)逆、適采需求(qiu)，又要滿(man)(man)足棉(mian)(mian)(mian)花(hua)加工質量(liang)需求(qiu)，還要滿(man)(man)足紡織企業對棉(mian)(mian)(mian)花(hua)質量(liang)的(de)(de)需求(qiu)，則(ze)這一棉(mian)(mian)(mian)花(hua)品種(zhong)(zhong)就要同時具(ju)備綜(zong)合(he)性(xing)(xing)狀(zhuang)優(you)(you)良(liang)(liang)的(de)(de)特(te)點。當前，源(yuan)棉(mian)(mian)(mian)8號已在阿克蘇、巴州等(deng)地(di)示(shi)范推廣(guang)10萬畝左(zuo)右。未來(lai)，李(li)雪源(yuan)團隊將圍繞源(yuan)棉(mian)(mian)(mian)8號品種(zhong)(zhong)優(you)(you)勢(shi)特(te)性(xing)(xing)，做好良(liang)(liang)種(zhong)(zhong)繁育(yu)和(he)良(liang)(liang)種(zhong)(zhong)良(liang)(liang)法配套，更(geng)好發(fa)揮該品種(zhong)(zhong)優(you)(you)良(liang)(liang)的(de)(de)生(sheng)產(chan)性(xing)(xing)能(neng)潛力，同時做好示(shi)范推廣(guang)。
