“…According to Goggi et al (2008), seed quality is a very important factor that determines the early development and growth of agricultural crops. Therefore, all studies to improve yield and nutrition of plants should take into account seed quality, which as this author defined is a vitality and vigour character, facilitating the production of normal seedlings within a very wide range of conditions found in the field.…”

Fractionation of seeds is a process commonly used by breeding and seed production companies. Separation of seeds into small, medium and large size fractions depends on a thousand kernel weight and thus on the content of the endosperm of the seeds, which is used in the process of embryo germination. Research showed that large seeds were characterized by a higher field germination capacity and generally seedlings had greater weight compared to those obtained from small seeds. The question then arises whether such fractionation would promote plant yield improvement. Yields of maize (Zea mays L.) plants of cv. 'Boruta' obtained from different size fractions (of different thousand kernel weight) were evaluated in the years 2005-2007. A three-year field experiment showed that yielding of the plants depended on the seed size fraction and decreased with an increase in the size of maize seeds sown. Moreover, in the experiment the germination value of seeds was assessed in cold (10°C) and warm (25°C) tests. The highest germination capacity in both the warm and the cold test (79.0% and 74.0%, respectively) was observed in the small seed size fraction. Germination of large seeds in the cold test was by 6.71% lower (a significant difference) than that of small seeds. The amylolytic activity of three fractions was also examined as indicated by dry and swollen seeds. The results showed the highest activity of amylases in small seeds (7.33 mg maltoze g dry matter-1 min-1) and the lowest in large seeds (4.12 mg maltoze g dry matter-1 min-1).

“…It is widely used in the corn seed industry to determine the fitness of a corn seed lot for emergence and survival under stressful conditions in the field (AOSA, 2009). It has also been used for early selection of inbred lines with improved seed vigor in a Midwest corn breeding program Goggi et al, 2008) and to screen subtropical hybrids (Shah et al, 2002). This same test could be used for preliminary screening of sorghum plant introductions for cold tolerance.…”

Sorghum [Sorghum bicolor (L.) Moench] is well known for its great potential for producing grain, feed, and fuel under stressful conditions such as drought and heat. However, its genetic potential to withstand cold, wet environments at germination has not been extensively exploited because of limited sources of early‐season cold tolerance. The objective of this study was to select novel, not previously characterized, cold‐tolerant sorghum accessions that can germinate in a traditional cold test at 10°C in the laboratory and emerge in the field under a wide range of stressful conditions. Fifty‐six accessions (38 Kaoliangs and 18 non‐Kaoliang of different geographic origin) were screened in the laboratory using a 7‐d and a 14‐d cold test at 10°C with soil, and they were also evaluated under early planting conditions in the field at two locations in the Midwest. The 7‐d cold test was the best predictor of seed emergence in the field (r = 0.50–0.61), while the standard germination test overestimated field performance. Twelve of the top 15 accessions exhibiting cold tolerance in the 7‐d cold test were also ranked within the top 15 under field conditions. Eight novel accessions were identified in this experiment with potential superior alleles for cold tolerance. Breeders could perform preliminary screening of germplasm for cold‐tolerant alleles in the laboratory using the 7‐d, 10°C cold test.

Combining ability of popcorn lines for seed quality and agronomic traits

et al. 2011

Popcorn breeding programs in Brazil have emerged but despite some advances there is still a lack of material performance studies specially regard to seed quality, in different agricultural seasons. This research was carried out to estimate the popcorn combining ability from biparental crosses between eight tropical and one temperate lines in two agricultural seasons (2008 and 2009) with regard to eight traits related to seed quality, in addition to three agronomic traits related to popping expansion. Method 4, proposed by Griffing (Model 1), was used to verifying the importance of the dominance effect in the genetic control of the seed quality traits, favouring the identification of superior hybrids through seed tests in the laboratory with low cost. The lines from Zélia and CMS42 were promising in obtaining hybrids with superior seed quality and greater popping expansion. The hybrids Zélia 9 IAC-112, CMS42 9 UEM M2-1, CMS43-1 9 IAC-112 and UEM M2-2 9 Zaeli expressed superior SCA for grain yield, popping expansion and at least two seed quality traits. These hybrids are materials of interest for cultivation in different planting seasons.
