铁春三号小麦新品种,表现高产稳产、优质、抗病、抗逆性强,适应性较广。产量稳定性好、千粒重稳定性亦好,回归系数都接近于1,离差方差 (S~2d)接近于0。穗粒数稳定性较好,改善环境条件,有利于穗粒增多。要获得高产必须在稳定千粒重的基础上,保证基本苗数,增加穗粒数而获得高产稳产。 Iron Spring No. 3 new wheat varieties, the performance of high and stable yield, high quality, disease resistance, strong resistance, wide adaptability. Yield stability, grain weight stability is also good, the regression coefficients are close to 1, the deviation of variance (S ~ 2d) is close to 0. Spike grain number is better stability, improve environmental conditions, is conducive to grain spike. To obtain high yield must be based on the stability of 1000-grain weight, to ensure that the basic number of seedlings, increase the number of grains per spike and get high and stable yield.
