本研究结果表明,在旱田条件下,水稻和陆稻杂种一代的单株谷重、单株草重、每穗总粒数、每穗实粒数、谷草比、株高等表现为较强的正向优势,全生育期和成穗率表现为明显的负向优势。杂种一代的株高、穗长、单株最高茎数、单株有效茎数、每穗实粒数、单株草重、谷草比、千粒重、抽穗日数、着粒密度与双亲平均值呈显著或极显著的正相关,杂种一代的三个产量构成因素与双亲平均值呈显著的相关性。
The results showed that under dryland conditions, the grain weight per plant, grass weight per plant, total grains per panicle, seed number per panicle, grain-to-grain ratio, To advantage, the whole growth period and the ear rate showed a significant negative advantage. The hybrid generation had significant differences in plant height, ear length, maximum number of stem per plant, number of effective stalks per plant, number of solid grains per panicle, grass weight per plant, grain-grass ratio, grain weight per thousand, days of heading, There was a significant positive correlation between the three yield components of hybrids and the average of parents.
