Alternatives to sowing vegetable type soybeans BABT
Mannfredini,Edcarlos; Destro,Deonisio; Homechin,Martin; Sachsida,Gustavo; Miglioranza,Édison.
Today, soybean crops of the Tamba Kurodaisu cultivar are sown in beds prior to transplantation to the field. This planting system has caused crop failure due to damage to the root system. An experiment to test different sowing alternatives to obtain plantlets for cropping of food type big seeded soybean was set up with the following treatments: sowing in beds; sowing in 130 cm³ newspaper cups; sowing in test tubes of volumes of 30 cm³, 60 cm³ and 70 cm³; sowing in 70 cm³ disposable plastic cups; sowing on 90 cm³ styrofoam trays. A randomized complete block design was used, and the following traits were assessed: germination percentage; number of days to flowering; plant height at flowering; number of days to maturity; plant height at maturity; number of...

Comparison between the SPD and the SPDS methods for segregating generation advancement in soybean BABT
Destro,Deonisio; Bizeti,Henrique Stoco; Garcia,Leandro Anderlin; Fonseca,Inês Cristina de Batista; Montalván,Ricardo; Miglioranza,Édison.
The purpose of this work was to compare the SPD (Single Pod Descent) and SPDS (Single Pod Descent with Selection) methods for segregating generation advancement in soybean breeding. Sixteen populations derived from crosses among Japanese and adapted Brazilian soybean were used. The traits, number of days to flowering (NDF) and to maturity (NDM), plant height at flowering (PHF) and at maturity (PHM), and individual plant yield (IPY) were assessed. The populations obtained by SPDS showed values close to the variation in the populations obtained by SPD. Regression through the origin showed that both methods were equivalent for NDM in the F3 generation and for NDF in the F4 generation. For all other trait/generation combinations, SPDS yielded superior means....

Genetic analysis of seed morphological traits and its correlations with Grain yield in common bean BABT
Dalla Corte,Aline; Moda-Cirino,Vania; Arias,Carlos Alberto Arrabal; Toledo,José Francisco Ferraz de; Destro,Deonisio.
This work investigated the genetic control of seed morphological traits and its correlations with grain yield in common bean. Three crossings among bean cultivars with different growth habit and seed characteristics were analyzed. F1 progenies gave origin to F2, RC1P1F1 and RC1P2F1 generations. Random samples of seeds from F2 generations and parents, F1 and backcrossings were sown during the season 2003/2004. Plant grain yield and seed morphological traits were determined by a sample of 150 plants from F2 generations and 20 plants from parents, F1 and backcrosssings. Genetic effects involved in each crossing were obtained from estimates of genetic components means and genetic and environmental components of phenotypical variance. Results showed that the...

Path analysis under multicollinearity in soybean BABT
Bizeti,Henrique Stoco; Carvalho,Claudio Guilherme Portela de; Souza,José Roberto Pinto de; Destro,Deonisio.
This study aimed to establish the phenotypic correlations among several soybean traits with grain yield in direct and indirect effects using path analysis, and to compare alternative methods for minimizing the adverse effects of multicollinearity in estimating path coefficients. The experiment was conducted in greenhouse in a randomized complete block design with four replications. Nine soybean genotypes belonging to three seed size categories were used. The correlation studies and the path analysis showed that the seed size was not important for increased yield. The number of nodes and plant height at maturity showed significant correlation with grain yield. Using the least square methodology, the results obtained by path analysis under multicollinearity...

Selection for grain yield and quality in segregating generations of wheat BABT
Andrade,Alessandro Ramos de; Riede,Carlos Roberto; Scholz,Maria Brígida dos Santos; Destro,Deonisio; Fonseca,Ines Cristina de Batista.
The objective of the work was to combine simultaneous selection for grain yield and technological quality in elite segregating populations of wheat developed by the breeding program of IAPAR. Thirteen populations were chosen according to their potentiality of genetic variability in the F2 generation of the 1997 crop season. One hundred heads were selected from each population and sown as F3 head-rows in the following season. Visual selection of individual head-rows or lines was done for yield potential and maturity. Seeds of the selected lines were evaluated for Sedimentation Values as well as Protein Content. The populations were identified as C1 to C13, representing the different crosses. The number of F2:3 lines selected within populations varied from...
