新(xin)疆農(nong)業科學院李雪源團隊歷(li)時10余年選育的突破性棉(mian)花新(xin)品種源棉(mian)8號通過(guo)了(le)(le)國家農(nong)作物品種審定委員會(hui)審定，他們把棉(mian)農(nong)理想(xiang)能高產、抗蟲害(hai)、早熟的棉(mian)花種子變成了(le)(le)現實。

新疆作(zuo)為我國最大的(de)棉(mian)(mian)花(hua)(hua)生(sheng)產基地，棉(mian)(mian)花(hua)(hua)生(sheng)產區域廣(guang)闊、環境復雜多樣，若(ruo)要(yao)(yao)實現(xian)產業(ye)化(hua)發展(zhan)，則對棉(mian)(mian)花(hua)(hua)品(pin)(pin)(pin)(pin)種(zhong)(zhong)(zhong)(zhong)要(yao)(yao)求極高。然而(er)目前(qian)新疆棉(mian)(mian)花(hua)(hua)品(pin)(pin)(pin)(pin)種(zhong)(zhong)(zhong)(zhong)同質(zhi)化(hua)強，占主導地位的(de)大品(pin)(pin)(pin)(pin)種(zhong)(zhong)(zhong)(zhong)少，現(xian)有(you)品(pin)(pin)(pin)(pin)種(zhong)(zhong)(zhong)(zhong)要(yao)(yao)么(me)抗(kang)(kang)病性(xing)(xing)不(bu)足，要(yao)(yao)么(me)品(pin)(pin)(pin)(pin)質(zhi)不(bu)佳(jia)、產量(liang)不(bu)穩定，棉(mian)(mian)花(hua)(hua)品(pin)(pin)(pin)(pin)種(zhong)(zhong)(zhong)(zhong)應用局限性(xing)(xing)大，影(ying)響(xiang)新疆棉(mian)(mian)花(hua)(hua)產業(ye)的(de)高質(zhi)量(liang)發展(zhan)。新疆農(nong)業(ye)科學(xue)院研究員李(li)雪源介紹。在(zai)這一背景下，李(li)雪源團隊用了(le)(le)10多年的(de)時間，運用南繁加代技(ji)術(shu)，綜(zong)合結(jie)構設計育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)、聚(ju)合育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)和(he)分子標記選擇育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)等(deng)多項技(ji)術(shu)手(shou)段，攻克(ke)了(le)(le)棉(mian)(mian)花(hua)(hua)育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)中產量(liang)與質(zhi)量(liang)、產量(liang)與抗(kang)(kang)病性(xing)(xing)、早(zao)熟性(xing)(xing)與產量(liang)、早(zao)熟性(xing)(xing)與機采性(xing)(xing)、早(zao)熟性(xing)(xing)與抗(kang)(kang)病性(xing)(xing)等(deng)多項負(fu)相關難題，有(you)效(xiao)聚(ju)合了(le)(le)多個商業(ye)化(hua)育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)性(xing)(xing)狀指(zhi)標，培育(yu)(yu)出(chu)了(le)(le)新品(pin)(pin)(pin)(pin)種(zhong)(zhong)(zhong)(zhong)源棉(mian)(mian)8號(hao)，實現(xian)育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)新突(tu)破，顯著提升了(le)(le)新疆棉(mian)(mian)花(hua)(hua)育(yu)(yu)種(zhong)(zhong)(zhong)(zhong)水平。

源棉(mian)(mian)8號(hao)具有廣適性好(hao)(hao)(hao)(hao)、耐(nai)密性強、集中成熟性好(hao)(hao)(hao)(hao)、易管理(li)、鈴大(da)、抗(kang)旱耐(nai)鹽(yan)堿、耐(nai)高溫等特(te)(te)性，畝(mu)產籽棉(mian)(mian)達到(dao)700公斤(jin)左(zuo)右，比一(yi)般(ban)高產田(tian)產量高出200公斤(jin)左(zuo)右。此外，李雪源介紹到(dao)，綜(zong)合性能(neng)優(you)(you)(you)是源棉(mian)(mian)8號(hao)的最大(da)優(you)(you)(you)勢，也(ye)是作為突破性新品種(zhong)的最大(da)特(te)(te)點(dian)，該品種(zhong)將(jiang)對促進棉(mian)(mian)花(hua)均衡增(zeng)產、提質(zhi)增(zeng)效、棉(mian)(mian)農增(zeng)收發揮(hui)重要(yao)作用。據了解，一(yi)個(ge)棉(mian)(mian)花(hua)品種(zhong)不(bu)僅需(xu)要(yao)滿足棉(mian)(mian)花(hua)生產的高產、廣適、抗(kang)逆(ni)、適采需(xu)求(qiu)，又要(yao)滿足棉(mian)(mian)花(hua)加工質(zhi)量需(xu)求(qiu)，還要(yao)滿足紡織(zhi)企業(ye)對棉(mian)(mian)花(hua)質(zhi)量的需(xu)求(qiu)，則這(zhe)一(yi)棉(mian)(mian)花(hua)品種(zhong)就要(yao)同時具備綜(zong)合性狀(zhuang)優(you)(you)(you)良(liang)的特(te)(te)點(dian)。當前，源棉(mian)(mian)8號(hao)已在阿克蘇、巴(ba)州等地示范推廣10萬畝(mu)左(zuo)右。未來，李雪源團(tuan)隊將(jiang)圍繞源棉(mian)(mian)8號(hao)品種(zhong)優(you)(you)(you)勢特(te)(te)性，做好(hao)(hao)(hao)(hao)良(liang)種(zhong)繁育(yu)和良(liang)種(zhong)良(liang)法(fa)配套，更好(hao)(hao)(hao)(hao)發揮(hui)該品種(zhong)優(you)(you)(you)良(liang)的生產性能(neng)潛(qian)力(li)，同時做好(hao)(hao)(hao)(hao)示范推廣。
