Abstract

Pre-harvest sprouting is one of the main factors that reducing the Rice grain yield and quality in humid weather condition with raining at harvest time. Thirty four local and improved Rice cultivars were evaluated for Pre-harvest sprouting and some related characteristics to this trait at in vivo condition. Analysis of variance results indicated that the differences between Rice genotypes were significant for Pre-harvest sprouting and some other traits of grain. Genotypic and phenotypic correlation coefficients of Pre-harvest sprouting with Alpha amylase activity were positive, this result showed that the Alpha amylase activity had significant effect on Pre-harvest sprouting. All Rice cultivars classified into three groups by Cluster analysis using ward method. First group included 24 cultivars and second and third groups included 4 and 6 cultivars respectively. In total, cultivars of the first and third groups had the lowest of Pre-harvest sprouting rate, so they were resistant to germination before harvest and the cultivars of second group had the highest of Pre-harvest sprouting rate, so they were sensitive to germination before harvest. Results of this experiment showed some local Rice cultivars such as Domsefid and Hashemi, with high resistance to Pre-harvest sprouting could potentially be used in breeding programms.
