摘要
冀麦29的选育及应用,进一步明确了适应旱作农业发展的抗逆性育种模式和目标,即以高效的“源、流”和大“库”容为前提,以抗旱节水为特点,以适应性广泛为优势。冀麦29的突出特点是:耐旱性强、抗寒性好、抗条锈、省水喜肥,生产潜力大,适应范围广。在干旱、半干旱地区推广应用,对缓解麦田需水矛盾和提高中低产麦区产量有着重大意义。该品种在黑龙港地区试验、示范、推广应用中,增产效果显著,平均比对照种增产17.8％,种植面积迅速扩大,现已发展到36万多亩。
The Selection and application of Jimai 29 further defined the brceding model and abjcitisn which Should have The character of Saoing water, drought resistance and the Superiority of wide adaptability for aduerse resisfauce in wheat breeding in ordder to snik the development or the drgland agriculture. Jimai 29 is characteriZed by strong drought and coled resistance, strip rust resistance Saving water with fertilizer. great pndutive potentiality and wide range of adaptability. Growing in the arid or Semiarid land, it has an important Significance for mitigating the contradiction of demanding water and for raising wheat production in middle of Cow-yield area. This variety has achieved nutable effect, which was 17,8 percent more than control in yeld, in Heilonygang area In addition. The acreagc under this uaricty is increasing rapidly from 137000Mu in 1987 to 360000Mu in 1988.
