1. Productive potential and castor bean selection of the FCA-PB cultivar progenies
ABSTRACT Castor bean is a very important crop, however, in Brazil it still has relatively low productivity, 0.47 Mg ha-1 as a mean. Besides that the Country has significant castor oil demand and depends on international commerce to complement its production. The solution of these problems goes through the development of genotypes highly productive and adapte

3. Resistance of the wild tomato Solanum habrochaites to Phytophthora infestans is governed by a major gene and polygenes
Abstract: This work aimed to study the inheritance of resistance to Phytophthora infestans in tomato plants, using the maximum likelihood estimation function. The susceptible cultivar Santa Clara (Solanum lycopersicum) was used as the female genitor and the P. infestans resistant S. habrochaites f. glabratum accession (BGH 6902) as the male genitor. F1 plant

4. Pure line selection in a heterogeneous soybean cultivar
Abstract Although cultivars of autogamous plants are homogeneous genotypes, they may show natural variability due to mechanical mixing, natural hybridization, and mutation. The aim of the present study was to estimate genetic and phenotypic parameters and to identify and select superior genotypes that associate good performance in traits of interest from a h

5. Development of superior lines of papaya from the Formosa group using the pedigree method and REML/Blup procedure
ABSTRACT Developing superior lines based on a simultaneous response from many traits of agronomic importance is a fundamental strategy to expand papaya cultivar supply, mainly the much-needed cultivars belonging to group Formosa. Our goal was to associate the pedigree method with REML/Blup procedure to select plants of progenies F2:3 with superior agronomic

6. Tomato progenies selection in Rondônia, Brazil
RESUMO O objetivo deste trabalho foi selecionar progênies endogâmicas de tomate, a partir da cultivar Yoshimatsu e realizar teste de progênies no estado de Rondônia, seguindo o delineamento de blocos ao acaso com quatro repetições e oito plantas por parcela, num espaçamento de 1x0,5 m, conduzidas com uma haste. Mediante analise dos resultados verifico

7. Genetic variation and gain in progenies of crambe
Abstract The objective of this study was to estimate the genetic variability of a Brazilian cultivar of crambe, as well as to estimate the genetic gain, with selection focusing on grain yield in crambe. Eighty two progenies were selected within the FMS Brilhante cultivar in 2009. The progenies were evaluated in 2010 and 2011 in Botucatu and São Manuel, Sao

8. Breeding common bean populations for traits using selection index
A common bean (Phaseolus vulgarisL.) cultivar must combine desirable genotypes for several traits in order to be accepted by producers and consumers. This study aimed to evaluate selection efficiency when segregating bean populations for traits, by means of a selection index, in order to obtain superior progenies for traits considered. A total of 16 populati

9. Melhoramento genético do cafeeiro (Coffea arabica L.) visando resistência durável à ferrugem e estabilidade fenotípica por meio de seleção recorrente
Os programas de melhoramento genético do cafeeiro têm dado ênfase à obtenção de cultivares resistentes à ferrugem, para minimizar os prejuízos causados pela doença à cafeicultura brasileira. O desenvolvimento de cultivares resistentes e/ou tolerantes as pragas e doenças têm papel importante no aumento de produtividade, diminuição de custos de p

10. AssociaÃÃo entre arquitetura da planta e a produtividade do feijoeiro do mesmo "pool" gÃnico. / Association between plant architecture and grains yield of common bean with the same gene pool.
The objective of this study was to verify if progenies with erect plant architecture display the same yield potential as progenies with no erect architecture, from the same segregating population. Crosses were made between the prostate cultivar BRSMG Majestoso with three erect cultivars (BRS Horizonte, BRS Supremo and BRS Valente), yielding three populations

11. Desempenho agronômico de cultivares de soja em diferentes épocas de semeadura no cerrado do Distrito Federal
In the Brazilian Savannahs, as a general breeding procedure, cultivars, progenies and other soybean genotypes are grown under ample environmental conditions, before they are released to cultivation. The variations comprise different soil types, fertility levels, moisture regime, sowing dates, temperature and cultivation patterns. An outstanding cultivar in o

12. Allele frequency and selection efficiency in cross populations of Andean x Mesoamerican common beans (Phaseolus vulgaris L. Fabales, Fabaceae)
Strategies were investigated for improving efficiency in the use of segregating common bean (Phaseolus vulgaris) populations using crosses between the Andean cultivar BRS-Radiante and the Mesoamerican parent cultivar Carioca-MG by developing populations with 12.5%, 25%, 50%, 75% and 87.5% of the allele frequency of one of the parents. For each of the five po
