Effects of planting dates on growth, yield components and yield of promising temperate cereal lines

Abstract

The objective of this study was to determine the optimal planting date for promising temperate cereal lines. The planting dates were varied into 1) Mid-November 2) Early-December 3) Mid December and 4) Early January. The promising temperate cereal lines consisted of 4 groups (bread wheat of 10 lines/variety, durum wheat of 10 lines, triticale of 10 lines and barley of 10 lines/variety) that were obtained from the Samoeng Rice Research Center, Samoeng District, Chiang Mai Province, Thailand. The results showed that the bread wheat should be planted with PMPBWS89013, FNBW8301-5-5, FNBW8310-1-SMG-1-1-1, Lampang 2, Lampang 5 and Fang 60 and triticale should be planted with MHSTCS07034, MHSTCS07035, MHSTCS07037, MHSTCS07038, MHSTCS07050, MHSTCS07053 and MHSTCS07093 in mid-November to mid-December. Durum wheat should be planted with MHSDWS07024, MHSDWS07025, MHSDWS07027 and MHSDWS07100 and barley should be planted with SMGBLS94027 and Samoeng 1 in mid-December to early-January as it gave the highest average growth, yield components and grain yield.
