520 ## - SUMMARY, ETC.
Summary, etc. Our objective was to investigate the relationships between spike traits, grain number and yield potential and their physiological basis in a doubled-haploid (DH) population derived from a cross between a CIMMYT spring wheat (Triticum aestivum L.) advanced line of large-spike phenotype (LSP2; +Tin1 tiller inhibition gene) and the UK winter wheat cultivar Rialto (R; &#8722;Tin1) of conventional spike phenotype. Field experiments were carried out in high radiation, irrigated conditions in NW Mexico in two seasons. Comparing the two groups of +Tin1 and &#8722;Tin1 DH lines, results showed the presence of the +Tin1 gene for tiller inhibition increased spike partitioning index (spike DM/above-ground DM at GS61 + 5 d; SPI) from 0.32 to 0.34 (+6.3%) (P < 0.01) and grains spike&#8722;1 by 5.1 (+13.9%) (P < 0.001), but reduced spikes m&#8722;2 by 20.7 (&#8722;5.7%) (P < 0.01). Overall a significant increase in grains m&#8722;2 of 865 (+6.6%) was observed in +Tin1 DH lines compared to &#8722;Tin1 DH lines (P < 0.05), but the effect on grain yield was not statistically significant. Above-grouund biomass at anthesis was not significantly affected by the presence/absence of the Tin1 gene; although results indicated the presence of the Tin1 gene increased photosynthetically active radiation interception from onset of stem elongation to anthesis, but decreased radiation-use efficiency during this phase. Our results indicated that introgressing the +Tin1 gene into modern wheat germplasm may offer scope to increase grains spike&#8722;1 and grains m&#8722;2 in irrigated, high radiation environments.
