河北省农科院棉花研究所将抗虫基因转入原“杂29”亲本,育成“抗虫杂29”,使其既保留了原杂交种的优良种性,又具有与新棉33B相当的抗虫性。 1 特征特性 “抗虫杂29”属中早熟杂交种,生育期130天,株高90厘米,植株塔型,叶中等大小,出苗快,易全苗。前中期生长势强,早熟不早衰。单株结铃性强,脱落率低,铃卵圆稍尖,铃壳薄,
The Cotton Research Institute of Hebei Academy of Agricultural Sciences transferred the insect-resistant gene into the original “Hybrid 29” parent and bred “Insect-resistant Hybrid 29”, which not only retains the excellent hybridity of the original hybrid, but also has the same new cotton 33B Insect resistance. 1 Characteristics of “Insect-resistant hybrid 29” is a premature hybrids, growth period of 130 days, height 90 cm, plant tower, leaf medium size, fast emergence, easy whole seedlings. Strong growth in the first mid-term, precocious puberty does not premature. The bolls of the plant are strong, the shedding rate is low, the bell oval is slightly pointed, the bell shell is thin,
