HIGHER LINT PERCENT AND DROUGHT TOLERANT COTTON LINE SELECTED BY RADIATION BREEDING

HE Zhuo Pei ZHOU Qing Qi XU Shu Ping XU Jun (Shanghai Institute of Plant Physiology, Chinese Academy of Sciences, Shanghai 200032, China) SHI Wei Jun ZHU Wen Jin (Institute of Industrial Crops, Xinjiang Academy of Agricultural Sciences of China, Urumqi 830000, China)  
The Gossypium hirsutum cv. Liaomian No. 9 were mutagenized by 60Co γ ray, from which the mutant line Zhonghuzhi PI 935 (be called "PI 935" for short) was bred by family selection method. The PI 935 not only has some good traits (growing period, drought tolerance, lint color and fiber quality) similar to the original cultivar, but also has higher lint outturn and lint yield than that of the Liaomian No. 9. The PI 935 has been identified and regional tested in nine places times for four years in the southern Xinjiang Weiwuer autonomous region. It was shown that the PI 935 had the higher lint outturn for the average 47.3 % was ten-point percentage more than that of the check cultivars (Junmian No. 1 or Xinluzhong No. 5 ) , the similar lint yield by and large and the growing period by five days later than that of the checks. The PI 935 was collected in the National Bank of Crop Germplasm (u-nified No. ZM 114274 and named " Zhonghuzhi PI 935").
