ABSTRACT Correlations and path analysis between characteristics can aid the selection of important attributes in breeding programs. Thus, the objective of this work was to perform genotypic, phenotypic correlations and path analysis under commercial yield of garlic bulbs, depending on morphological and agronomic variables. The experiment was carried out in 2017 at the Universidade Federal dos Vales do Jequitinhonha e Mucuri and Universidade Federal de Lavras, using ten garlic genotypes, eight trials and two commercial cultivars, Caçador and Jonas. We evaluated: plant height; number of leaves, total bulb number; total bulb mass, total bulb yield, marketable bulb yield and number of cloves per bulb. The genotypic and phenotypic correlations were positive and significant between marketable yield of bulbs with bulb mass, total yield and number of cloves per bulb, indicating that selection based on these characteristics will help increase the yield of garlic. However, only the number of cloves per bulb had a direct effect and a relevant indirect effect on the marketable yield of garlic.

Character association and path analysis in twenty genotypically diverse indigenous genotypes of garlic (Allium sativum L.) were studied at the Central Institute of Temperate Horticulture, Srinagar during the years 2010 and 2011 for nine important characters. Total bulb yield showed positive and significant genotypic and phenotypic associations with plant height, number of leaves per plant, pseudo-stem length, bulb weight and number of cloves per bulb, indicating that selection based on these traits will help increasing the yield of garlic. Path coefficient analysis provides an effective means of a critical examination of specific force action to produce a given correlation and measure the relative importance of each factor. In this analysis bulb yield was taken as dependant variable and rest characters were considered as independent variable. Bulb weight showed high positive and direct effect and significant positive correlation with total bulb yield. Therefore, bulb with higher weight should be considered in selection criteria for increasing the total bulb yield and emphasis should be given for selecting the genotypes with higher bulb weight. Overall path analysis indicated that direct effect of bulb weight and equatorial bulb diameter and indirect effect of plant height, number of leaves per plant, pseudo stem length, polar bulb diameter, equatorial bulb diameter, number of cloves per bulb and average weight of 50 cloves should be considered simultaneously for amenability of total bulb yield.

ABSTRACT The objective of this study was to analyze the phenotypic correlation and path analysis of traits related to plant architecture, earliness and grain yield in F2, BC1 and BC2 generations, from crosses between cowpea cultivars BRS Carijó and BR14 Mulato. Most phenotypic correlations of the examined traits were concordant in statistical significance, with approximate values among the examined generations. For the trait seed weight, significant and positive phenotypic correlations were observed in the three generations only for the trait number of secondary branches. The values of the direct effects were in agreement with the values of the phenotypic correlations, which indicate true association by the phenotypic correlation among the traits of grain yield examined. Path analysis indicated that the selection of productive plants will result in early plants and an increased number of secondary branches. In F2, plants with shorter length of the main branch and shorter length of secondary branches can be obtained. The causal model explained 15 to 30% of the total variation in grain weight in relation to the traits examined. The analyses indicated the possibility of selecting plants with a higher and early grain yield, shorter length of primary branches and lower number of nodes, which are important variables for mechanical or semi-mechanical harvesting.

Yield performance of primocane-fruiting experimental blackberry (Rubus spp.) cultivars from two breeding programs were evaluated in the southern Appalachian Mountains. The trial consisted of the nine experimental cultivars: NC 533, NC 534, NC 535, NC 537, NC 538, NC 539, APF-27, APF-46, and Prime-Jim®. In addition, rowcovers were applied to split plots in the spring to determine if harvest dates could be advanced. In 2007, five experimental cultivars had comparable high total yields (APF-27, APF-46, NC 535, NC 537, and NC 539), yet only three of these had comparable marketable yields (APF 27, APF-46, and NC 537). In 2008, APF-27 and APF-46 had significantly higher total yield (2234.5 and 2257.3 g/plant, respectively) and marketable yield (1611.2 and 1654.2 g/plant, respectively) than all other experimental cultivars. Rowcover treatments did not increase or decrease either total or marketable yield in any of the experimental cultivars in either year. In addition, rowcovers did not advance the date of 5% or 50% harvest in either year. On the basis of the conditions imposed in these studies, we determined that “APF” selections evaluated in this trial have higher second-year yield than “NC” selections, primocane-fruiting experimental cultivar yields are lower than yields commonly found with floricane-fruiting blackberries, and rowcovers as applied in this study are not a viable option for advancing harvest season of primocane-fruiting blackberries in the southern Appalachian Mountains.

Onion varieties were evaluated for adaptability to the climatic conditions in South Ari woreda. Three varieties of onion were planted under a complete randomized block design experiment with three replications at research field in Jinka Agricultural research Center (South Ari woreda of South Omo zone SNNPRS of Ethiopia). The quantitative data on bulb yield, plant height, bulb size and number of leaves of onion varieties were collected. All the varieties were harvested at their maturity (90% tops down) and then weighed. Statistical methods were used for data analysis where by analysis of variance was applied. It was concluded that the three varieties (treatment) combinations, namely Adama red, Nasick red and contribute similarly to the total yield, plant height, number of leaves and bulb size. The variety local was the best onion variety as it produced the highest bulb yield of 3.3167 kg/plot numerically. Based on varietal characteristics of relative bulb size, good yield, easy availability of seeds and cheaper price of seeds in the local market, we recommend farmers to use local variety followed by Nasick red and Adama red therefore, government should promote these onion varieties for cultivation in South Ari especially for jinka and its vicinity. Government can import to ensure the availability of Local and Nasick red varieties so that farmers can be motivated for adoption of these varieties for commercial production. The effects of different planting dates on the yield of onion varieties can be considered for future research.

Background: Onion (Allium cepa L.) is an important and indispensable item of every kitchen. It is used as a vegetable, spice and condiment and commands an extensive internal market. Even though onion is one of the major crops in India, its cultivation is not yet popular in Kerala. Successful onion production depends on the selection of varieties that are adapted to different conditions imposed by specific environment and best planting time. In this background, the current study aimed to evaluate five onion varieties in the tropical planes of Kerala and also to study the effect of different planting time and varieties on the performance of onion in Kerala.Methods: Five onion varieties were evaluated in four different dates of planting with an interval of fifteen days. Planting commenced from 10th November to 25th December 2017 in a split plot design with four replications. Yield attributing characters such as number of leaves per plant, leaf length, bolting percentage, neck thickness, bulb weight and yield were noted. Result: All the parameters showed a significant variation over different dates of planting. There was a significant variation in number of leaves per plant, leaf length, bolting percentage, total bulb yield and neck thickness among the varieties. Interaction effect of varieties and dates of planting was significant only for leaf length and total bulb yield. Highest bulb weight was recorded in 25th Nov. planting. Highest yield was recorded in 25th Nov. which was on par with 10th Dec. and 10th Nov. plantings. Arka Kalyan recorded a highest yield, which was statistically on par with Agrifound Dark Red and Arka Pragati. Varieties when planted on 25th Dec. recorded a lowest neck thickness. Agrifound White exhibited a non-bolting behavior in all the dates of planting. Overall performance and yield of onion was found to be better when planting was done on 25th November.

ABSTRACT The aim of this study was to select S3 progenies of super sweet corn based on agronomic performance, evaluated in topcrosses with the narrow genetic base tester Honey Sweeter (Seminis®). The experiment was carried out in Guarapuava-PR. We evaluated 22 topcross hybrids and three checks, in two sowing times, in randomized blocks design with three replications. Six traits were evaluated: total yield of husked ears, commercial yield of husked ears, grain yield, grain length, ear diameter and total soluble solids content. Considering the set of evaluated traits, the topcrosses with progenies D2-07, D3-28, D4-53 and D5-24 were superior to the others; therefore, these progenies should continue in the inbreeding process and be evaluated in crosses with elite inbred lines with potential to generate competitive super sweet corn single hybrids.

The aim of the study was to evaluate the dependence of potato crops on the level of irrigation in three mesoregions of Poland. The field experiments were carried out in 2009–2011 according to an obligatory methodology for evaluation of crop cultivars. Three factors were tested: two cultivation practices (with irrigation and without irrigation as control), five potato cultivars, and three locations (Masłowice, Szczecin-Dąbie, and Węgrzce). The study was conducted in randomized blocks in triplicate. The study included the same nutrition across locations and protection against potato blight. Irrigation was applied according to the criterion of optimal soil moisture at a humidity decrease below 70% of the field water capacity. At the time of harvest, total and commercial yields of tubers were determined. Detailed analysis of the dependent variables, total and marketable yield, and the independent variables for the second harvest date, confirmed confidence in the achieved results. The coefficients of variation for total and marketable yield, on the second harvest date, were 23% and 25%, respectively, which means high stability for the results. Irrigation of potato plantations contributed to an increase in the total yield of tubers in the first harvest term by 3.22 t·ha−1 and by 7.23 t·ha−1 -in the second term; and the commercial yield of tubers by 3.45 t·ha−1 in the first term and by 7.42 t·ha−1 -in the second term of tuber harvest. The highest watering efficiency in the first harvest time, 60 days after planting, was distinguished by the “Miłek” variety, and in the second harvest date by the “Denar” variety.

Abstract The Atlantic Forest has very high levels of biodiversity and is considered one of the most important and threatened biomes in the world. Balfourodendron riedelianum is one of the forest’s characteristic tree species that is currently under considered endangered due to timber extraction and forest fragmentation. With the goal of generating information that may contribute to the genetic conservation of B. riedelianum, genetic parameters are estimated for quantitative traits important for silviculture in a provenance and progeny test located in the Experimental Station of Luiz Antônio, São Paulo State, Brazil. The test was established in 1986 and consists of three provenances, from which open-pollinated seeds from 19 seed trees were collected. The following traits were evaluated at 32 years of age: diameter at breast height (DBH), total height (H), stem height (SH), stem straightness (SS), and forking (FOR). The estimates were carried out using the REML/BLUP method. Significant genetic variation among progenies was detected for all traits (except SH) and between provenances for DBH. The coefficient of individual genetic variation (CVgi) ranged from 2.5 to 9.5 %. The mean heritability among progeny ( $h_f^2$ ) was substantial for DBH (0.44) and FOR (0.36), enabling the selection of families with the highest DBH and lowest FOR for population improvement. Genotypic and phenotypic correlations among traits were also found. We conclude that there is genetic variability in the population that can be exploited in future breeding programs and for the genetic conservation of the species.

An experiment was carried out from December 2005 to July 2006, in the Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM), in Diamantina, Minas Gerais State, Brazil, aiming at selecting sweet potato clones for the Alto Vale do Jequitinhonha. We evaluated nine clones from the UFVJM germplasm bank, using cultivars Brazlândia Branca, Brazlândia Roxa, and Princesa as controls. The experimental design was blocks at random, with four replications. Plants were harvested seven months after transplanting. We assessed the fresh mass yield of vines and roots, as well as root shape and resistance to soil insects. Genotypes did not differ from each other for the fresh mass yield of vines (ranging from 3.81 to 11.76 t ha-1). The total yield of roots ranged from 22.0 to 45.4 t ha-1 and clones BD-06, BD-113-TO, BD-15, BD-38, BD-25, BD-61, and cultivar Princesa had statistically the highest figures. However, only clone BD-06 significantly overcame the control cultivars Brazlândia Branca and Brazlândia Roxa. Clone BD-06 had also the highest commercial yield of roots (38.58 t ha-1), statically similar to most of the other clones and cultivar Princesa (25.87 t ha-1), but superior to cultivars Brazlândia Branca and Brazlândia Roxa. Most of the clones tested, including clone BD-06, produced good shaped roots and were resistant to soil insects. Considering our results, clone BD-06 stood out as a good option for growing sweet potato in the Upper Valley of Jequitinhonha.
