The researchers studied how different growing conditions affected the starch and protein content in triticale grain and the amylose content in starch. They looked at four types of triticale harvested in two locations over two years. They found that the starch and amylose content were mainly influenced by the type of triticale and the year of harvest. The protein content was only affected by the year of harvest. They also discovered a negative relationship between protein and starch content, and a positive relationship between starch and amylose content.
