玉米自交系耐盐碱性鉴定研究初探
A Preliminary Study on Saline-alkali Tolerance Identification of Different Maize Inbred Lines
摘要
Abstract
The saline-alkaline tolerance of maize skeleton inbred lines were evaluated , of which were classed into different grades through the determination of the saline-alkaline tolerance index in the whole growth stage in this study .The results showed that ,the saline-alkaline tolerance index of mature plant rate ,plant height ,green leaf num-ber ,seed number per spike and seed-producing percentage were positive related to the yield ,which the saline-alka-line tolerance index of seed-producing percentage and yield reached significant level .This study also concluded that higher mature plant rate at tasseling-silking stage ,relatively more green leaf number after silking ,more seed number per spike and seed-producing percentage at seed mature stage was the premise to obtain high yield .Compared with other skeleton inbred lines ,Qi 319 inbred lines had a stronger saline-alkaline tolerance .关键词
