【摘要】 以品系克交00—786石豆为试验材料,采用随机区组设计,重复三次。试验结果表明:石豆出苗期和成熟期分别晚12 d和7 d;石豆在株高、百粒重上差异不显著;在前期营养生长上差异显著;在产量上减产达极显著水平。研究初步确定品种特性与品种和环境的互作是石豆产生原因。更多还原

【Abstract】 In order to discover the characteristic of the "hard seed",to clarify the reason of its generation,and provide scientific basis for breeding,a line Kejiao 00-786 hard seed was used in this study with random block design and three replications.The results showed that the date of emergence and maturity were 12 days and 7 days later respectively.The plant height and the 100-seed weight were not significant.The difference of vegetative growth was significant.The reduction in yield was significant fearfully.It was concluded that the interaction of variety and environment was the reason for the generation of "hard seed".更多还原
