The root rot/stem "rot/charcoal rot" disease caused by Macrophomina phaseolina (Tassi.) Goid is one of the most destructive disease in all sesame growing areas. To improve tolerance and/or resistance of sesame to this pathogen, two cycles of pedigree selection under artificial infection of were done at Fac. Agric. Assiut Univ. Expr. Farm. Assiut, Egypt. The genetic materials were the F2, F3 and F4 generations of two populations. The experiments were done in the three successive seasons of 2018 to 2020. The F2 was sown in nor-replicated experiments, and the F3 and F4 were raised in RCBD of three replications. The selection criteria were days to 50% flowering (earliness), plant height (PH), height to first capsule (HFC), length of fruiting zone (LFZ) and seed yield/plant (SY/P). The infection % in the F2 ranged from 53.67 to 80.43%. The remained genotypic coefficient of variation in the F4 was high and enough for further cycles of selection for HFC, LFZ and SY/P. Heritability in broad sense of the selection criteria in the F4-generation was very high and unreliable. However, the narrow sense heritability was low to moderate. After two cycles of selection, the direct observed genetic gain from the mid-parent was significant (p ≤ 0.01) and reached -6.06 and -12.15% for earliness,14.66 and 5.82% for PH, 32.35% and 19.19% for LFZ and 43.89 and 36.67% for SY/P for pop1 and pop2, respectively. The infection% decreased significantly by selection. Single trait selection was an effective method to improve the selection criterion, but in some cases, it was accompanied with adverse effects on the other correlated traits. To overcome this problem selection index combined the favorable traits could be recommended.

Phenological growth stages ofSolanum sessiliflorumaccording to BBCH scale

2015

Solanum sessiliflorum is becoming an economically important crop in many parts of South and Central America. For accurate information to be given for crop management and research, it is highly desirable to have a universal scale for describing its growth stages. This study adapted the codes of the general BBCH scale to S. sessiliflorum. Detailed descriptions of vegetative and reproductive growth, from germinating seeds to adult plants, as well as principal and secondary growth stages, are provided in a two-and three-digit decimal code. Seven out of the ten principal developmental stages from BBCH scale were described for S. sessiliflorum: germination, leaf development, branches development, inflorescence emergence, flowering, fruit development and fruit ripening. Applications of the BBCH scale for this species in both research and crop management are discussed.

BBCH [Biologische Bundesanstalt (Julius Kühn-Institut), Bundessortenamt, CHemische Industrie] scales are used in applied natural sciences for the description of phenological growth stages of plants and are available for many crops today. Currently, a specific BBCH scale for Asparagus officinalis, a perennial vegetable plant of worldwide interest, does not exist. In this study, an extended BBCH scale was developed, describing precisely the growth stages of A. officinalis. Nine principal growth stages were defined and subdivided into several secondary growth stages resulting in a two-digit decimal code. Detailed descriptions of the particular stages and illustrations were included to clarify the application of the code system. The scale is proposed to specify and harmonise research activities as well as to enhance comparability of crop management practices for growers of asparagus.
