普通杏(Armeniaca vulgaris)种质资源果实主要数量性状变异及概率分级
Variation and probability grading of main quantitative traits of apricot (Armeniaca vulgaris) germplasm
摘要
Abstract
[Objective]Genetic resources evaluation, based on the reasonable grading of the fruit quantitative characters, is an important part of research work. The fruit quantitative characters of 143 to 478 apricot accessions were investigated with statistical analysis and probability grading. [Method]The fruit quantitative characters were graded based on the Kolmogorov-Smiromov (K-S)normality test and X2 test, including average fruit weight, firmness of fresh, soluble solid content, soluble sugar content, titratable acid content, Vitamin C content, weight of fresh stone, weight of dried stone and weight of dried kernel [Result]Large variation present in apricot fruit quantitative characters. The largest coefficient of variation occurs in fruit firmness (5546%) and the smallest in soluble solid content (14,95%). According to the K -S normality test, the quantitative characters which conformed to the normal distribution divided into five grades by four points: (X-1.2818S), (X-0.5246S), (X+0.5246S) and (X+ 1.2818S). Occurrence probabilities of the first to the fifth grades were 10% ,20%, 40%, 20% and 10% respectively. The grading standards were discussed for the characteristics conforming to normal distribution based on X2 test. [Con-clusion]There is abundant genetic diversity in Chinese apricot fruit, and probability grading in the fruit quantitative characters is an ideal result.关键词
