新疆農(nong)(nong)業科(ke)學院李(li)雪源團(tuan)隊歷時10余(yu)年選(xuan)育的(de)突破性棉(mian)花新品種源棉(mian)8號通過了國家農(nong)(nong)作物品種審(shen)定委員會審(shen)定，他(ta)們把棉(mian)農(nong)(nong)理想能高(gao)產、抗(kang)蟲(chong)害、早(zao)熟(shu)的(de)棉(mian)花種子變成了現(xian)實。

新(xin)(xin)疆作為我國最大的(de)棉(mian)(mian)(mian)花(hua)(hua)生(sheng)產(chan)基地(di)，棉(mian)(mian)(mian)花(hua)(hua)生(sheng)產(chan)區域廣闊、環(huan)境復雜(za)多樣(yang)，若要(yao)實現(xian)(xian)產(chan)業(ye)化發展(zhan)，則對棉(mian)(mian)(mian)花(hua)(hua)品種(zhong)要(yao)求極(ji)高。然而(er)目前新(xin)(xin)疆棉(mian)(mian)(mian)花(hua)(hua)品種(zhong)同質化強(qiang)，占(zhan)主導地(di)位(wei)的(de)大品種(zhong)少(shao)，現(xian)(xian)有品種(zhong)要(yao)么(me)抗(kang)病性(xing)(xing)不足(zu)，要(yao)么(me)品質不佳、產(chan)量不穩定，棉(mian)(mian)(mian)花(hua)(hua)品種(zhong)應(ying)用(yong)局(ju)限性(xing)(xing)大，影(ying)響新(xin)(xin)疆棉(mian)(mian)(mian)花(hua)(hua)產(chan)業(ye)的(de)高質量發展(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，李雪源(yuan)團(tuan)隊用(yong)了(le)10多年的(de)時間，運用(yong)南繁加(jia)代技術，綜合(he)結構設計(ji)育(yu)(yu)(yu)(yu)種(zhong)、聚合(he)育(yu)(yu)(yu)(yu)種(zhong)和分子標記選擇育(yu)(yu)(yu)(yu)種(zhong)等多項技術手段(duan)，攻克了(le)棉(mian)(mian)(mian)花(hua)(hua)育(yu)(yu)(yu)(yu)種(zhong)中(zhong)產(chan)量與(yu)(yu)質量、產(chan)量與(yu)(yu)抗(kang)病性(xing)(xing)、早熟(shu)性(xing)(xing)與(yu)(yu)產(chan)量、早熟(shu)性(xing)(xing)與(yu)(yu)機(ji)采性(xing)(xing)、早熟(shu)性(xing)(xing)與(yu)(yu)抗(kang)病性(xing)(xing)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)(yu)(yu)種(zhong)性(xing)(xing)狀指標，培育(yu)(yu)(yu)(yu)出了(le)新(xin)(xin)品種(zhong)源(yuan)棉(mian)(mian)(mian)8號，實現(xian)(xian)育(yu)(yu)(yu)(yu)種(zhong)新(xin)(xin)突破，顯著提升了(le)新(xin)(xin)疆棉(mian)(mian)(mian)花(hua)(hua)育(yu)(yu)(yu)(yu)種(zhong)水平。

源棉(mian)(mian)(mian)8號(hao)具有廣(guang)適性(xing)(xing)好(hao)、耐密性(xing)(xing)強(qiang)、集中成熟(shu)性(xing)(xing)好(hao)、易管(guan)理、鈴大、抗旱耐鹽堿、耐高(gao)溫(wen)等(deng)特性(xing)(xing)，畝(mu)產(chan)籽棉(mian)(mian)(mian)達到700公(gong)斤(jin)左(zuo)右，比(bi)一般高(gao)產(chan)田(tian)產(chan)量(liang)高(gao)出200公(gong)斤(jin)左(zuo)右。此(ci)外，李(li)雪(xue)(xue)源介(jie)紹到，綜合性(xing)(xing)能優(you)是源棉(mian)(mian)(mian)8號(hao)的(de)最大優(you)勢，也是作為(wei)突破性(xing)(xing)新品(pin)(pin)種(zhong)(zhong)(zhong)的(de)最大特點，該品(pin)(pin)種(zhong)(zhong)(zhong)將對(dui)促(cu)進棉(mian)(mian)(mian)花(hua)(hua)均衡增(zeng)產(chan)、提質(zhi)增(zeng)效(xiao)、棉(mian)(mian)(mian)農增(zeng)收(shou)發(fa)揮(hui)重要(yao)作用。據了解，一個棉(mian)(mian)(mian)花(hua)(hua)品(pin)(pin)種(zhong)(zhong)(zhong)不僅需要(yao)滿足棉(mian)(mian)(mian)花(hua)(hua)生產(chan)的(de)高(gao)產(chan)、廣(guang)適、抗逆、適采需求(qiu)，又要(yao)滿足棉(mian)(mian)(mian)花(hua)(hua)加工(gong)質(zhi)量(liang)需求(qiu)，還要(yao)滿足紡織企業對(dui)棉(mian)(mian)(mian)花(hua)(hua)質(zhi)量(liang)的(de)需求(qiu)，則這一棉(mian)(mian)(mian)花(hua)(hua)品(pin)(pin)種(zhong)(zhong)(zhong)就要(yao)同(tong)(tong)時(shi)具備(bei)綜合性(xing)(xing)狀優(you)良(liang)的(de)特點。當(dang)前，源棉(mian)(mian)(mian)8號(hao)已(yi)在(zai)阿克蘇、巴州等(deng)地示(shi)范推廣(guang)10萬(wan)畝(mu)左(zuo)右。未來，李(li)雪(xue)(xue)源團隊將圍繞源棉(mian)(mian)(mian)8號(hao)品(pin)(pin)種(zhong)(zhong)(zhong)優(you)勢特性(xing)(xing)，做好(hao)良(liang)種(zhong)(zhong)(zhong)繁育和良(liang)種(zhong)(zhong)(zhong)良(liang)法配套，更(geng)好(hao)發(fa)揮(hui)該品(pin)(pin)種(zhong)(zhong)(zhong)優(you)良(liang)的(de)生產(chan)性(xing)(xing)能潛力，同(tong)(tong)時(shi)做好(hao)示(shi)范推廣(guang)。
