新疆(jiang)農(nong)業科學院李雪源(yuan)團(tuan)隊歷(li)時(shi)10余年選育(yu)的突(tu)破性棉(mian)花(hua)新品種源(yuan)棉(mian)8號通過了(le)國家農(nong)作物品種審(shen)定委員會審(shen)定，他們把棉(mian)農(nong)理想能高(gao)產(chan)、抗蟲害、早熟的棉(mian)花(hua)種子變成了(le)現實。

新(xin)(xin)疆作(zuo)為我國最大的(de)棉(mian)(mian)花生(sheng)產基(ji)地，棉(mian)(mian)花生(sheng)產區域廣闊、環境(jing)復雜多(duo)(duo)樣，若要(yao)實現(xian)產業(ye)化(hua)發展，則對棉(mian)(mian)花品種(zhong)(zhong)(zhong)(zhong)要(yao)求(qiu)極高。然而目前新(xin)(xin)疆棉(mian)(mian)花品種(zhong)(zhong)(zhong)(zhong)同質(zhi)化(hua)強，占主導地位的(de)大品種(zhong)(zhong)(zhong)(zhong)少，現(xian)有(you)品種(zhong)(zhong)(zhong)(zhong)要(yao)么(me)抗(kang)病性(xing)(xing)不足，要(yao)么(me)品質(zhi)不佳、產量不穩定，棉(mian)(mian)花品種(zhong)(zhong)(zhong)(zhong)應用局限性(xing)(xing)大，影響(xiang)新(xin)(xin)疆棉(mian)(mian)花產業(ye)的(de)高質(zhi)量發展。新(xin)(xin)疆農業(ye)科學院研究員李(li)雪源(yuan)介紹。在這一(yi)背景下，李(li)雪源(yuan)團隊用了(le)10多(duo)(duo)年的(de)時間，運用南繁加代技術，綜合(he)結構設計育種(zhong)(zhong)(zhong)(zhong)、聚(ju)合(he)育種(zhong)(zhong)(zhong)(zhong)和分子(zi)標記選擇育種(zhong)(zhong)(zhong)(zhong)等多(duo)(duo)項技術手段(duan)，攻克了(le)棉(mian)(mian)花育種(zhong)(zhong)(zhong)(zhong)中產量與(yu)質(zhi)量、產量與(yu)抗(kang)病性(xing)(xing)、早(zao)熟(shu)性(xing)(xing)與(yu)產量、早(zao)熟(shu)性(xing)(xing)與(yu)機采(cai)性(xing)(xing)、早(zao)熟(shu)性(xing)(xing)與(yu)抗(kang)病性(xing)(xing)等多(duo)(duo)項負(fu)相關難題，有(you)效聚(ju)合(he)了(le)多(duo)(duo)個商業(ye)化(hua)育種(zhong)(zhong)(zhong)(zhong)性(xing)(xing)狀指標，培育出(chu)了(le)新(xin)(xin)品種(zhong)(zhong)(zhong)(zhong)源(yuan)棉(mian)(mian)8號，實現(xian)育種(zhong)(zhong)(zhong)(zhong)新(xin)(xin)突破，顯著提升了(le)新(xin)(xin)疆棉(mian)(mian)花育種(zhong)(zhong)(zhong)(zhong)水平。

源(yuan)(yuan)棉(mian)(mian)(mian)8號具(ju)有(you)廣(guang)適性(xing)(xing)(xing)(xing)好、耐密性(xing)(xing)(xing)(xing)強(qiang)、集中成熟性(xing)(xing)(xing)(xing)好、易管(guan)理(li)、鈴大、抗(kang)旱耐鹽堿、耐高溫等特性(xing)(xing)(xing)(xing)，畝(mu)產(chan)籽棉(mian)(mian)(mian)達到700公斤左右，比一般高產(chan)田(tian)產(chan)量(liang)高出200公斤左右。此外，李(li)雪(xue)(xue)源(yuan)(yuan)介紹到，綜合(he)性(xing)(xing)(xing)(xing)能(neng)優是源(yuan)(yuan)棉(mian)(mian)(mian)8號的(de)最大優勢，也是作(zuo)為突破性(xing)(xing)(xing)(xing)新品(pin)(pin)種的(de)最大特點，該品(pin)(pin)種將(jiang)對促進棉(mian)(mian)(mian)花均衡增產(chan)、提質增效、棉(mian)(mian)(mian)農(nong)增收發揮(hui)重要作(zuo)用。據了解，一個棉(mian)(mian)(mian)花品(pin)(pin)種不僅需要滿(man)足(zu)棉(mian)(mian)(mian)花生產(chan)的(de)高產(chan)、廣(guang)適、抗(kang)逆(ni)、適采需求(qiu)，又要滿(man)足(zu)棉(mian)(mian)(mian)花加工(gong)質量(liang)需求(qiu)，還要滿(man)足(zu)紡織企業對棉(mian)(mian)(mian)花質量(liang)的(de)需求(qiu)，則這一棉(mian)(mian)(mian)花品(pin)(pin)種就要同時(shi)具(ju)備綜合(he)性(xing)(xing)(xing)(xing)狀(zhuang)優良(liang)的(de)特點。當前，源(yuan)(yuan)棉(mian)(mian)(mian)8號已在阿克(ke)蘇(su)、巴州等地示(shi)(shi)范推廣(guang)10萬畝(mu)左右。未來，李(li)雪(xue)(xue)源(yuan)(yuan)團隊將(jiang)圍繞源(yuan)(yuan)棉(mian)(mian)(mian)8號品(pin)(pin)種優勢特性(xing)(xing)(xing)(xing)，做(zuo)好良(liang)種繁(fan)育和(he)良(liang)種良(liang)法(fa)配套，更好發揮(hui)該品(pin)(pin)種優良(liang)的(de)生產(chan)性(xing)(xing)(xing)(xing)能(neng)潛力，同時(shi)做(zuo)好示(shi)(shi)范推廣(guang)。
