陕西省小麦品种粉质特性的研究

研究了三类小麦材料粉质特性各参数间、地点间和年际间的变异特点以及各参数间的关系,结果表明:各粉质参数在品种间、地点间和年际间的变异大小都是形成时间、稳定时间、弱化度和粉质质量数等远大于评价值,而评价值又远大于吸水率;同一参数在不同品种间的变异大小也不尽相同;各品种的不同参数虽在年际间、地点间均有较大的变异系数,但并未达到显著水平;大部分参数间的相关和回归系数均达到极显著水平。说明粉质性状主要由遗传因素决定,外因只起修饰性作用,大部分参数之间可以较可靠地相互预测。

Studies of Farinogram Parameters on Wheat Cultivars of Shaanxi Province

This paper studies the variability, correlation coefficient and regression coefficient between farinogram parameters on three types wheat cultivars of Shaanxi Province in different location and different years. The results shows: the variability of Development Time, Stable Time, Softening of Dough and Farinogram Quality Number is absolutely higher than Valorimeter Value, and Valorimeter Value is absolutely higher than Water Absorption; the variability of the same farinogram parameters is different among cultivars; the variability of the different farinogram parameters of several cultivars is rather high in different locations and different years, but it isn''t at variation significance levels ;most of the correlation coefficient and regression coefficient between the farinogram parameters reach absolutely significance levels .From above on ,we may get a conclusion which farinogram parameters is decided by genetic factors.
