Abstract Background Brassica napus is an important oilseed crop cultivated worldwide. During domestication and breeding of B. napus, flowering time has been a target of selection because of its substantial impact on yield. Here we use double digest restriction-site associated DNA sequencing (ddRAD) to investigate the genetic basis of flowering in B. napus. An F2 mapping population was derived from a cross between an early-flowering spring type and a late-flowering winter type. Results Flowering time in the mapping population differed by up to 25 days between individuals. High genotype error rates persisted after initial quality controls, as suggested by a genotype discordance of ~ 12% between biological sequencing replicates. After genotype error correction, a linkage map spanning 3981.31 cM and compromising 14,630 single nucleotide polymorphisms (SNPs) was constructed. A quantitative trait locus (QTL) on chromosome C2 was detected, covering eight flowering time genes including FLC. Conclusions These findings demonstrate the effectiveness of the ddRAD approach to sample the B. napus genome. Our results also suggest that ddRAD genotype error rates can be higher than expected in F2 populations. Quality filtering and genotype correction and imputation can substantially reduce these error rates and allow effective linkage mapping and QTL analysis.

ABSTRACT The high luminosity rates and high annual average temperatures of the Brazilian semiarid region, combined with the use of irrigation and adaptability of the sunflower crop to local climate, favor increased achene yield due to acceleration of morphophysiological processes. The objective of this work was to evaluate the morphophysiological and productive characteristics of sunflower varieties grown under drip irrigation in the Sub-Mid São Francisco River Valley. The experiment was conducted in the Experimental Field of the Brazilian Agricultural Research Corporation (Embrapa Semiarid), in Petrolina, State of Pernambuco, Brazil, in a randomized block design, with 21 sunflower varieties and four replications. The variables evaluated were flowering time, plant height, number of live leaves, stem and capitulum diameter, number of lodged and broken plants, stem curvature, relative chlorophyll index, photosynthesis, stomatal conductance, transpiration, average leaf temperature, 1000-achene weight and achene yield of the sunflower varieties. The treatments presented flowering time of 43 to 59 days after sowing, plant height of 1.0 to 1.4 m, capitulum diameter of 0.154 to 0.221 m, chlorophyll content of 30.8 to 33.98 Spad units and 1000-achene weight of 35.61 to 80.30 g. The sunflower varieties V7 and V8 stood out, with achene yields above 2,960 kg ha-1 and low number of lodged and broken plants, indicating a greater adaptability irrigation crops in the Sub-Mid São Francisco River Valley.

We investigated the effect of paclobutrazol as preplant bulb soaks on plant heightof Iris x hollandica cv. ‘Frans Hals’ and ‘Blue Magic’cultivars which were grownin pots. Bulbs of iris were soaked into gibberellin inhibitor paclobutrazol solutionat 0, 15, 30 ppm before planting. Effect of paclobutrazol on the flowering time,flower diameter and length, leaf length, plant height, flower life, and chlorophyllcontent of leaves were determined. The shortest plant height was obtained from the‘Blue Magic’ cultivar treated with 30 ppm paclobutrazol which gave plants with11.3 cm, 68% shorter than untreated control. ‘Frans Hals’ cultivar treated with 30ppm paclobutrazol was 20.9 cm and 50% shorter than control. In ‘Blue Magic’ and‘Frans Hals’cultivars the lower dose of 15 ppm paclobutrazol were also effectiveon height control with 11.8 and 21.5 cm plant height, respectively. This gibberellininhibitor also shortened the leaf length of iris cultivars. Paclobutrazol treatmentsresulted in higher chlorophyll content per unit area in the leaves. The highestchlorophyll content (57.00 CCI) was obtained from the ‘Blue Magic’ iris treatedwith 30 ppm paclobutrazol, while the control plants had 32.70 CCI chlorophyll intheir leaves. Chlorophyll content of ‘Frans Hals’ treated with 30 ppm paclobutrazolwere 52.87 CCI, while control plants of this cultivar were 28.80 CCI. Plantsapplied with paclobutrazol resulted with smaller flower diameter compared to thecontrol plants of both cultivars. The smallest flower diameter was obtained from 30ppm paclobutrazol treatment with 38.83 mm in ‘Blue Magic’ iris while the controlof this cultivar was 99.63 mm. The flower diameter of ‘Frans Hals’ cultivar treatedwith 30 ppm paclobutrazol was 109.1 mm, while the control one was 112 mm.
