新疆農(nong)業科(ke)學院李雪源團隊(dui)歷時10余年選育(yu)的突(tu)破性棉花(hua)新品種(zhong)源棉8號通過了國家農(nong)作物品種(zhong)審定委員會審定，他們把棉農(nong)理(li)想(xiang)能高(gao)產、抗(kang)蟲害、早(zao)熟的棉花(hua)種(zhong)子(zi)變成了現實。

新(xin)(xin)疆作為我國最大的(de)棉(mian)花(hua)(hua)生產基(ji)地(di)，棉(mian)花(hua)(hua)生產區域(yu)廣闊(kuo)、環境復雜多(duo)樣，若要(yao)(yao)實現產業化發展，則對棉(mian)花(hua)(hua)品(pin)種(zhong)(zhong)(zhong)要(yao)(yao)求極高(gao)。然而目(mu)前新(xin)(xin)疆棉(mian)花(hua)(hua)品(pin)種(zhong)(zhong)(zhong)同質(zhi)(zhi)化強(qiang)，占主導地(di)位(wei)的(de)大品(pin)種(zhong)(zhong)(zhong)少，現有(you)品(pin)種(zhong)(zhong)(zhong)要(yao)(yao)么(me)抗病性(xing)(xing)不(bu)足(zu)，要(yao)(yao)么(me)品(pin)質(zhi)(zhi)不(bu)佳、產量(liang)不(bu)穩定，棉(mian)花(hua)(hua)品(pin)種(zhong)(zhong)(zhong)應(ying)用(yong)局限性(xing)(xing)大，影響新(xin)(xin)疆棉(mian)花(hua)(hua)產業的(de)高(gao)質(zhi)(zhi)量(liang)發展。新(xin)(xin)疆農業科學(xue)院研(yan)究員李雪源(yuan)介紹(shao)。在這一背景下，李雪源(yuan)團隊用(yong)了10多(duo)年的(de)時間，運用(yong)南繁(fan)加代技(ji)術，綜合(he)結構設計(ji)育(yu)(yu)(yu)種(zhong)(zhong)(zhong)、聚合(he)育(yu)(yu)(yu)種(zhong)(zhong)(zhong)和分子標記選擇(ze)育(yu)(yu)(yu)種(zhong)(zhong)(zhong)等多(duo)項技(ji)術手段，攻克了棉(mian)花(hua)(hua)育(yu)(yu)(yu)種(zhong)(zhong)(zhong)中產量(liang)與(yu)質(zhi)(zhi)量(liang)、產量(liang)與(yu)抗病性(xing)(xing)、早熟性(xing)(xing)與(yu)產量(liang)、早熟性(xing)(xing)與(yu)機采性(xing)(xing)、早熟性(xing)(xing)與(yu)抗病性(xing)(xing)等多(duo)項負相關難(nan)題，有(you)效聚合(he)了多(duo)個(ge)商業化育(yu)(yu)(yu)種(zhong)(zhong)(zhong)性(xing)(xing)狀指(zhi)標，培育(yu)(yu)(yu)出(chu)了新(xin)(xin)品(pin)種(zhong)(zhong)(zhong)源(yuan)棉(mian)8號，實現育(yu)(yu)(yu)種(zhong)(zhong)(zhong)新(xin)(xin)突破，顯著提(ti)升了新(xin)(xin)疆棉(mian)花(hua)(hua)育(yu)(yu)(yu)種(zhong)(zhong)(zhong)水平。

源(yuan)棉(mian)8號(hao)(hao)具(ju)(ju)有廣(guang)(guang)(guang)適(shi)性(xing)好、耐密性(xing)強、集中成熟(shu)性(xing)好、易管理、鈴(ling)大、抗旱(han)耐鹽堿、耐高溫(wen)等特(te)性(xing)，畝產(chan)(chan)籽棉(mian)達(da)到(dao)700公斤左(zuo)右，比一(yi)(yi)般高產(chan)(chan)田產(chan)(chan)量高出200公斤左(zuo)右。此外，李(li)雪源(yuan)介紹到(dao)，綜(zong)合性(xing)能優(you)(you)是源(yuan)棉(mian)8號(hao)(hao)的(de)最(zui)大優(you)(you)勢，也是作為突破性(xing)新品種(zhong)(zhong)的(de)最(zui)大特(te)點，該品種(zhong)(zhong)將(jiang)對促進(jin)棉(mian)花(hua)(hua)均衡增(zeng)(zeng)產(chan)(chan)、提質(zhi)增(zeng)(zeng)效、棉(mian)農增(zeng)(zeng)收發揮(hui)重(zhong)要(yao)作用。據了(le)解(jie)，一(yi)(yi)個棉(mian)花(hua)(hua)品種(zhong)(zhong)不(bu)僅需要(yao)滿(man)足(zu)棉(mian)花(hua)(hua)生產(chan)(chan)的(de)高產(chan)(chan)、廣(guang)(guang)(guang)適(shi)、抗逆、適(shi)采(cai)需求(qiu)，又要(yao)滿(man)足(zu)棉(mian)花(hua)(hua)加工質(zhi)量需求(qiu)，還要(yao)滿(man)足(zu)紡織企業(ye)對棉(mian)花(hua)(hua)質(zhi)量的(de)需求(qiu)，則這一(yi)(yi)棉(mian)花(hua)(hua)品種(zhong)(zhong)就要(yao)同(tong)時具(ju)(ju)備綜(zong)合性(xing)狀優(you)(you)良(liang)的(de)特(te)點。當(dang)前，源(yuan)棉(mian)8號(hao)(hao)已在阿克(ke)蘇、巴(ba)州等地示(shi)范(fan)推廣(guang)(guang)(guang)10萬畝左(zuo)右。未(wei)來，李(li)雪源(yuan)團隊(dui)將(jiang)圍繞(rao)源(yuan)棉(mian)8號(hao)(hao)品種(zhong)(zhong)優(you)(you)勢特(te)性(xing)，做(zuo)好良(liang)種(zhong)(zhong)繁(fan)育和良(liang)種(zhong)(zhong)良(liang)法配套，更好發揮(hui)該品種(zhong)(zhong)優(you)(you)良(liang)的(de)生產(chan)(chan)性(xing)能潛(qian)力，同(tong)時做(zuo)好示(shi)范(fan)推廣(guang)(guang)(guang)。
