TY - JOUR TT - Nutrient Use and Uptake Efficiency in Wheat and Triticale Genotypes under Low and Optimum Input Conditions AU - Vats, Akshay Kumar PY - 2016 DA - July JF - Ekin Journal of Crop Breeding and Genetics JO - Ekin Journal PB - Bitki Islahçıları Alt Birliği WT - DergiPark SN - 2149-1275 SP - 95 EP - 100 VL - 2 IS - 2 KW - Nutrient use efficiency KW - wheat and triticale KW - N KW - P KW - Zn content in wheat N2 - N, P and Zn content, harvest index and grain yield were used to evaluate diverse 32 wheat and triticale genotypescategorized in four groups i.e. Triticum aestivum, Triticum durum, synthetic wheat and triticale genotypes. The genotypesdiffered significantly for all the characters indicating considerable variation for improvement of these traits. The varietiesLoK1 and HD2687 were having highest grain yield under low and optimum input conditions respectively, while HD 2687showed maximum percent of increase over low input conditions. PBW343 and P7307 were having highest harvest indexunder low and optimum input conditions respectively, whereas Syn5 was found to show highest percent of increase overlow input conditions. As nutrient use and uptake parameters are concerned, for N content triticale genotypes TL2963and TL2967 showed highest content under low and optimum input conditions, while percent increase over low inputconditions was found to be highest in HD2687 (285.96 per cent). Genotypes TL2966 and Syn36 were having highest Pcontent under low and optimum input conditions respectively among all the four groups, while TL2969 responded betterover low input conditions. Among all the four groups triticale genotype TL2963 showed trend having high content of zincunder both low and optimum input conditions, whether for percent of increase over low input conditions P7531 respondedbetter. Path coefficient analysis revealed that harvest index followed by biological yield had the direct effect under bothconditions. CR - Anonymous (2010).
