Autores: Andrade Junior,Aderson S. de; Bastos,Edson A.; Ribeiro,Valdenir Q.; Athayde Sobrinho,Candido; Silva,Paulo H. S. da.
ABSTRACT This study aimed to evaluate the stalk yield of ten sugarcane cultivars (RB962962, RB931011, RB931530, RB98710, RB92579, RB867515, RB863129, SP791011, RB72545 and VAT90212) subjected to water deficit, full irrigation and water surplus by subsurface drip irrigation, during three cropping seasons (2011-2014). The experiment was conducted at the Experimental Field of Embrapa Meio-Norte, Teresina, Piauí State, Brazil, in dystrophic Red Yellow Argisol. The cultivars RB962962 (162.3 Mg ha-1) and RB867515 (158.5 Mg ha-1) have better stalk yield compared with other cultivars in all water regimes and cropping seasons.

The objective of the present study was to evaluate the adaptability and stability of corn hybrids for grain yield in environments with high crop management standards. Ten corn hybrids were evaluated for grain yield in 48 environments, consisting of 12 locations over a period of four years inSouth Brazil. A complete experimental, random block design with two repetitions was used. Adaptability and stability were analyzed according to the bi-segmented discontinuous model with measurement errors in the variables. The behavior of hybrids was studied as a function of the average yield in the inferior and/or superior environments, the estimates of the parameters of the equation, and the quality of the fit. The 30F36 hybrid behaved better in the superior...

The objective of this research was to analyze the use of cultivar index selection (GARCIA, 1998) in the indication of superior genotypes of common bean for the northwest region of the state of Rio de Janeiro, in comparison to the other nonparametric indices used in plant breeding. The indexes of ELSTON (1963), MULAMBA &amp; MOCK (1978), SCHWARZBACH (1972) and GARCIA (1998) were employed in the evaluation of 14 strains (F9 e F10) of common bean of indeterminate growth habit. The experiments were conducted in the municipalities of Bom Jesus do Itabapoana (2010 and 2011) and Cambuci (2011). The design employed was of randomized blocks with four repetitions. The traits pod yield (PRODV), grain yield (PRODG), average number of pods per plant (NMVP), average...
