我省棉区气候特点是温度低、无霜期短,在棉花生育期间常遇低温冷害,产量不高不稳。为了尽快选育出早熟、耐低温能力强的棉花新品种,我所于1969年以株系“646—197”为母本,以株系“6579—5293”为父本进行杂交,在原有试材的基础上,经定向选择和异地鉴定,育成极早熟、耐低温、高产、优质棉花新品系“6913”。主要特征特性如下:一、生物学特征:平均株高45.8厘米,植株塔形,较紧凑,果
Cotton climate in our province is characterized by low temperature, frost-free period is short, low temperature chilling damage often occurs during the growth of cotton, the yield is not high and unstable. In order to breed as soon as possible a precocious, low temperature resistant cotton varieties, I in 1969 to strain “646-197” as the female parent, strain “6579-5293” as the male parent hybridization, in the original test Based on the selection of materials and the identification of different places, bred “6913”, a new cotton line with very early maturity, low temperature resistance, high yield and good quality. The main features are as follows: First, the biological characteristics: average height 45.8 cm, plant tower, more compact, fruit
