【摘要】：【目的】研究我國(guó)西北地區(qū)水地春小麥基因型與環(huán)境的交互作用及其產(chǎn)量的穩(wěn)定性,為我國(guó)西北水地春小麥高效生產(chǎn)提供相關(guān)依據(jù).【方法】對(duì)2009-2010年由16個(gè)試點(diǎn)、15個(gè)新品種(系)組成的中國(guó)西北水地春小麥區(qū)域試驗(yàn)的產(chǎn)量資料進(jìn)行方差分析和GGE分析.【結(jié)果】在我國(guó)西北水地春小麥生產(chǎn)區(qū),基因型與環(huán)境互作效應(yīng)對(duì)產(chǎn)量變異的影響約為品種效應(yīng)的4.68倍,品種間豐產(chǎn)性、穩(wěn)產(chǎn)性均較理想的品種占供試品種的40%,其中穩(wěn)產(chǎn)性差異較大,但部分品種仍對(duì)環(huán)境具有一定的特殊適應(yīng)性.16個(gè)試點(diǎn)可劃分為3個(gè)類型區(qū),其中在寧夏平羅(E_8)為代表的河套平原灌溉區(qū)表現(xiàn)最好的品種分別是‘寧春47’(G_6)、‘C78’(G_8)和‘巴豐6’(G_9),以青海西寧(E10)為代表的青藏高原寒旱區(qū)表現(xiàn)最好的品種‘銀春8’(G_(10)),以甘肅會(huì)寧(E4)為代表的黃土高原中部旱作區(qū)表現(xiàn)最好的品種‘蒙鑒11’(G_(12)).從環(huán)境代表性和對(duì)品種鑒別能力兩方面分析,環(huán)境代表性較理想的試點(diǎn)是青海西寧(E_(10)).鑒別力較好的是新疆塔城(E_(14))、新疆焉耆(E15)、寧夏平羅(E_8)、內(nèi)蒙古巴盟(E_1)、青海西寧(E_(10))、新疆溫泉(E_(16))、青海平安(E_(11))等.【結(jié)論】共篩選出‘甘春357786’(G_1)、‘隴春25’(G2)、‘E32-1’(G_3)、‘隴春’(G_5)、‘C78’(G_8)、和‘銀春8’(G_(10))高產(chǎn)、穩(wěn)產(chǎn)性較好的6個(gè)品系,‘寧春47’(G_6)在個(gè)別試點(diǎn)表現(xiàn)優(yōu)異;水地春小麥試點(diǎn)中代表性最好的是青海西寧(E_(10)).
[Abstract]:[stability of interaction and production of irrigated spring wheat genotypes in Northwest China and the environment of the objective], provide the basis for our country northwest spring wheat in irrigated land and efficient production. [Methods] to 2009-2010 by the 16 pilot, 15 new varieties (lines). Chinese northwest water wheat regional test yield data were analysis of variance and GGE. [results] in the northwest water wheat production area in China, genotype and environment interaction effect on yield variation is about 4.68 times the variety effect, varieties of high yield, stable yield were ideal varieties varieties accounted for 40%, of which yield the difference is large, but some varieties are still on the environment has certain special adaptability of.16 pilot can be divided into 3 types, including in Ningxia Pingluo (E_8) as the representative of the Hetao plain irrigation area the best varieties respectively "Ning 鏄，
