育种工作者为了选拔推广适应各种不同自然区域的农作物新品种,每年对新选育的品系,新杂交种或新引进的品种都进行丰产性、适应性、抗逆性与经济性状等鉴定试验,以便从中选拔提升优良品系参加区域、生产试验,为审定推广新品种提供科学依据。我省每年各种作物大约有八百个以上省、地、县不同级别的鉴定或区域试验点,对这些试验结果都要进行统计分析,并且要求数据可靠,计算准确,步骤清晰,处理意见明确。为此,育种工作者必须花费大量时间进行统计计算,而且稍有不慎就会出现错误,还需反复核算,对生物统计不熟悉的
In order to select and popularize new varieties of crops adapted to different natural regions, breeders carry out identification tests such as high yield, adaptability, resistance and economic traits to newly-selected lines, new hybrids or newly introduced varieties every year , In order to select and improve good strains to participate in regional and production trials to provide a scientific basis for validation and promotion of new varieties. Each year in our province, there are about 800 different types of appraisal or regional test points for different crops at provincial, prefectural and county levels. Statistical analysis should be carried out on the results of these tests, and the data required should be reliable, calculated accurately, the steps should be clear, and the treatment opinions should be clear . For this reason, breeders must spend a great deal of time in statistical calculations, and mistakes made only a little inadvertently require double counting, unfamiliar to biometrics
