Summary
Flour falling number (FN) is an important trait because not only related with pre-harvest sprouting (PHS) tolerance but also with processing quality. Waxy wheat usually has low flour falling number (FN) without severe pre-harvest sprouting (PHS). To identify quantitative trait loci (QTLs) associated with flour FN, a recombinant inbred line (RIL) population derived from two Chinese wheat, strong gluten wheat Gaocheng 8901 and waxy wheat Nuomai 1, was employed to evaluate the genetic variation and to detect QTLs based on DarT and SSR markers under three environments.

Summary
To assess the efficacy of near lethal heat stress for endodormancy release of Superior Seedless grapevine buds, single-node cuttings were soaked for 1 h in hot water (50°C) and then forced for one month. The effects of hot water treatment (HWT) on budburst, metabolic changes of carbohydrates, proline, free polyamines PAs [putrescine (Put), spermidine (Spd) and spermine (Spm)] and antioxidant enzymes activity were investigated in bud under forcing conditions. Near-lethal heat stress caused a transient increase in starch hydrolysis, leading to an abrupt accumulation of soluble sugars, especially sucrose concentration during the first 3 days after treatment.

Summary
An experiment was conducted to evaluate the effect of micro-sprinkler and drip irrigation with nitrogen fertigation on gas exchange traits, growth, yield and economics of Indian mustard during 2009-10 and 2010-11 under semi-arid conditions of Rajasthan, India. The experiment was conducted in split plot design, consisting of five irrigation systems in main plot viz. MS, MS+CB, DS, DS+CB and CB alone. Four nitrogen levels (N) 0, 40, 80 and 120 kg ha-1 were taken in the sub plots. The results revealed that MS and DS alone or in combination with CB influenced the physiological parameters including chlorophyll concentration, PAR, ICC, photosynthesis, transpiration and stomatal conductance.

Summary
Improving the nutritional quality of food is an important step in addressing worldwide health problems. A field experiment was conducted to evaluate the effects of either Se (0.03mM sodium selenate) or Si (1.5mM potassium silicate ) on the yield components as well as grain and straw qualities of rice cv. Giza 177 and cv. IET 1444 exposed to water deficit condition. Drought stress was imposed by withholding water (irrigation every 10 days). The plants were left to grow under the various treatments for five months. At full maturity (5 months after sowing) the experiment was terminated and grain quality in terms of grain appearance (grain length L, grain breadth B and L/B ratio), cooking quality (amylose content and water uptake WU) as well as nutritional (carbohydrates, proteins oil, phenols and flavonoid contents) and anti-nutritional (phytic and oxalic acids) values was estimated.

Summary
Habanero pepper (Capsicum chinense Jacq.) is one of the most cultivated plants in the world. We evaluated the physiological and molecular behavior of three habanero pepper varieties seedlings, two from the Yucatan region (Mayan Ek and Mayan Chan) and one commercial variety (SEMINIS), subjected to 10 days of nitrogen (N) deficiency treatment. Growth parameters, N compounds, net nitrate absorption, and CcNRT2.1 (Capsicum chinense high affinity nitrate transporter) gene expression were evaluated at 0, 2, 6, 8 and 10 days of the treatment.

Summary
The aim of this study was to evaluate the behavior of high-affinity nitrate (NO3-) transporters and plasma membrane H+-ATPase isoforms in rice varieties, contrasting in NO3- uptake kinetics parameters. Two varieties of rice were studied: cv. IAC-47 (improved for high N input) and cv. Piauν (a local landrace variety cultivated for low input farmers). We evaluated the expression of two PM H+-ATPase isoforms (OsA2 and OsA7), two NO3- transporters (OsNRT2.1 and OsNRT2.2), and OsNAR2.1, the rice regulatory genes for nitrate transport.

Summary
An experiment was conducted to evaluate the effect of micro-sprinkler and drip irrigation with nitrogen fertigation on gas exchange traits, growth, yield and economics of Indian mustard during 2009-10 and 2010-11 under semi-arid conditions of Rajasthan, India. The experiment was conducted in split plot design, consisting of five irrigation systems in main plot viz. MS, MS+CB, DS, DS+CB and CB alone. Four nitrogen levels (N) 0, 40, 80 and 120 kg ha-1 were taken in the sub plots. The results revealed that MS and DS alone or in combination with CB influenced the physiological parameters including chlorophyll concentration, PAR, ICC, photosynthesis, transpiration and stomatal conductance.

Summary
Improving the nutritional quality of food is an important step in addressing worldwide health problems. A field experiment was conducted to evaluate the effects of either Se (0.03mM sodium selenate) or Si (1.5mM potassium silicate ) on the yield components as well as grain and straw qualities of rice cv. Giza 177 and cv. IET 1444 exposed to water deficit condition. Drought stress was imposed by withholding water (irrigation every 10 days). The plants were left to grow under the various treatments for five months. At full maturity (5 months after sowing) the experiment was terminated and grain quality in terms of grain appearance (grain length L, grain breadth B and L/B ratio), cooking quality (amylose content and water uptake WU) as well as nutritional (carbohydrates, proteins oil, phenols and flavonoid contents) and anti-nutritional (phytic and oxalic acids) values was estimated.

Summary
In this paper we present a simulation study to investigate the influence of the pattern of missing values on the efficiency of the expectation-maximization AMMI (EM-AMMI) algorithm. Four scenarios are considered: one with cells missing completely at random; and three patterns with cells not missing at random (block-diagonal pattern, diagonal pattern and block-diagonal pattern with checks). The results are compared in terms of precision to estimate the missing cells and genotype selection.
