Phenotypical Variability

Maize grain has many and diverse uses in the food and feed industry. The diversity of applications requires characteristics of quality in accordance to that. To examine phenotypical diversity in the grain content, it was evaluated a total of 754 maize samples: 265 local populations (landraces); 59 synthetics/composites; 430 “TURDA” inbred lines for their grain quality attributes. Comparison of the inbred lines diversity is on average the most divergent in grain starch concentration (range value 19.9) from landraces (range value 11.8) and synthetics (range value 12.5). The grain oil and ash content showed high variability among the genotypes. The quality attributes in most of the cases showed positive phenotypic correlation except grain starch contents which was negatively correlated at phenotypic levels. The objective of this study was to evaluate the potential of maize “TURDA” germplasm in according to its grain quality content, such as: protein, oil, fiber, ash and starch concentration; to estimate the extent of phenotypical variability and correlation for various quality components to formulate a selection criterion in a breeding program.

Pod Wall

One means of increasing seed yield in white lupin may be the modification of the harvest index in the reproductive compartment by a reduction of the proportion of pod walls. Genetic and environmental effects on the pod wall proportion and yield components were evaluated. Thirty-five genotypes of spring-sown material were sown in 6 different locations across France in 1996 and 1997, accounting for a total of 10 site × year combinations. The existence of a genetic variation for the pod wall proportion among studied genotypes was demonstrated (0.26–0.34). Highly significant genotypic differences for the pod wall proportion, seed number per pod, seed weight per pod, mean seed weight, flowering time, and seed yield were observed among lupin genotypes. The heritability of pod wall proportion was moderate, the phenotypic correlation between this character and seed yield was significant and negative, and the genetic correlation was high and negative. The environmental variance contributed a major part of the total variation. The genotype × environment effect for the pod wall proportion was small, which suggests that the selection of genotypes with low and stable pod wall proportion in different environments will be possible. The strong negative genetic correlation between pod wall proportion and seed yield supports the feasibility of using the character as a selection criterion for a higher seed yield.

The aim of the research was to develop a cultivar of naked oat with improved traits of productivity and grain quality for cultivation under climate change conditions and utilization in breeding practice as a source of useful economic properties. The pre-flag leaf’s area was found to render a considerable effect on the formation of the number of grains and grain weight in the panicle and on the total biomass (r= 0.78-0.85), while the area of leaves depended on the duration of the period from seedling emergence to wax ripeness (r = ‒0.79) and on agroclimatic conditions during the growing season (HTC, r = 0.76).  The flag leaf’s pigments (Chl a, Chl b, Car) were observed to have a sizable effect on the weight of 1000 grains during the period from flowering to milk ripeness (r = 0.79-0.88). The new naked cultivar ‘Virovets’ (1h07) with improved levels of productivity and grain quality (1000 grain weight: 29.2 g; crude protein content: up to 19.8%; oil of the oleic-linoleic group: 7.71%, grain volume weight: 670 g/l; pubescence: weak) was developed to be cultivated for food and feed purposes and be used in naked oat breeding as a source of high grain quality.
