<p><strong>Background: </strong><em>Pepper huastecto yellow vein virus</em> (PHYVV) is one of the main viruses affecting pepper (<em>Capsicum</em> spp.) plants in Mexico.</p><p><strong>Question: </strong>Why there are no pepper resistant cultivars to PHYVV currently? Could it be due for the lack of new pepper resistant sources and knowledge about the heritability of the resistant trait?</p><p><strong>Study species: </strong><em>Capsicum annuum, Pepper huasteco yellow vein virus </em>and<em> Bemisia tabaci</em>.</p><p><strong>Study site: </strong>Culiacan<strong> </strong>Sinaloa, Mexico; January 2013 to August 2014.</p><p><strong>Methods: </strong>Two assays were performed in 2013 and 2014 with three resistant wild lines of <em>Capsicum annuum</em> in the S2 and S3 generation under greenhouse conditions to analyze the resistance to the <em>Pepper huasteco yellow vein virus</em> (PHYVV) and its heritability. Plants were inoculated with PHYVV through <em>Bemisia tabaci</em> G. and by grafting.</p><p><strong>Results: </strong>Line UAS12 showed a significantly higher proportion of resistant plants, longer incubation time, and less amount of viral DNA, followed by lines UAS13, UAS10 and the Maverick cultivar under both inoculation methods in both assays. Distribution of symptoms revealed a bimodal tendency in both assays. The novel gene "<em>CchGLP</em>" which confer resistance to PHYVV in pepper plants, was identified in the three lines evaluated on this study. Heritability of line UAS12 was of 0.35 and 0.26 in the insects and grafting inoculations, and of 0.58 and 0.10 in the first and second assays, respectively. Lines UAS13 and UAS10 showed close to zero heritability in the first and second assays with both inoculation methods.</p><strong>Conclusions: </strong>Line UAS12 is the most promising genetic resource for its high resistance and for showing heritability for the resistance trait. The intermediate resistance of lines UAS13 and UAS10 could be also useful for breeding programs. At least two genes are involved in the resistance trait to PHYVV. Part of the resistance shown in these lines may be due to the presence of the "<em>CchGLP</em>" gene. Line UAS12 count with variability for the resistant trait and can, therefore, be used to improve resistance and the other two lines possibly are stable as they did not show heritability.

Resistant Trait

Pepper huasteco yellow vein virus (PHYVV) is a major disease in pepper (Capsicum annuum) that causes quantitative and qualitative losses to the crop in Central America and part of North America. To date, no resistant cultivars are available, and breeding is hampered by the lack of knowledge of the inheritance of this trait. Sources of resistance to PHYVV have been identified in the wild peppers of Mexico. The objectives of this study were to determine the grade of dominance, to analyze the maternal influence, and to estimate the number of genes involved in this resistant trait to PHYVV in the resistant wild pepper accession UAS12. Three susceptible parent lines—‘Anaheim’ (Ana), ‘Ancho Gigante’ (AG), and ‘Yolo Wonder’ (YW)—were crossed with resistant UAS12 accession to develop F1 (reciprocal), F2, and BC1 progenies in three families. Plants from this study were inoculated with PHYVV through Bemisia tabaci, evaluated phenotypically, and the segregation of disease scores was studied. A single recessive gene was found to control resistance to PHYVV in the resistant UAS12 accession, although segregation patterns suggested that other minor genes could participate in the expression of this resistant trait. No proof was found for maternal inheritance of PHYVV resistance. The gene symbol phv is proposed for PHYVV resistance in UAS12 accession in pepper. These results provide useful information for the design of pepper breeding programs in the introgression of this trait into commercial pepper backgrounds.

Bemisia Tabaci Biotype B

The silverleaf whitefly, Bemisia tabaci biotype B, is currently one of the most important pests of melon, causing direct and indirect damage to plants, and significantly reducing production in the field. Due to the need for alternative methods of chemical control in melon crops, the melon cultivars AF-646, AF-682, Don Luis, Frevo, Jangada, Nilo, Vereda, Amarelo Ouro and Hales Best were assessed at field, greenhouse, and laboratory trials for resistance to whitefly B. tabaci biotype B. In general, 'Hales Best' and 'Amarelo Ouro' were the most resistant, showing oviposition non-preference against whitefly. The trichome density is associated with the variation in oviposition on the cultivars and should be further investigated in future work. These results may be helpful in melon breeding programs, focusing on plant resistance to B. tabaci biotype B.

Kutukebul Bemisia tabaci (Gennadius) biotipe B yang juga dikenal sebagai Bemisia argentifolii  (Gennadius) merupakan jenis biotipe yang lebih ganas dalam merusak tanaman dibandingkan dengan biotipe non-B. Saat ini kutukebul B. tabaci biotipe B telah dilaporkan keberadaanya di Indonesia. Informasi dasar, seperti siklus hidup, lama hidup, keperidian, dan kemampuan berkembang biak kutukebul sangat diperlukan sebagai dasar dalam menyusun strategi pengendalian hama kutukebul tersebut. Penelitian bertujuan untuk mempelajari siklus hidup dan statistik demografi kutukebul B. tabaci biotipe B dan non-B pada tanaman cabai. Penelitian dilakukan dengan mengamati perkembangan sejak telur sampai menjadi dewasa di growth chamber yang terkontrol suhu dan pencahayaannya. Pengamatan dilakukan terhadap beberapa aspek biologi dan beberapa parameter statistik demografi. Hasil penelitian menunjukkan bahwa kutukebul B. tabaci biotipe B memiliki beberapa aspek biologi yang berbeda dengan non-B pada tanaman cabai. Siklus hidup kutukebul B. tabaci biotipe B dan non-B masing-masing adalah 33,27 dan 30,86 hari. Kutukebul B. tabaci biotipe B memiliki laju reproduksi bersih (R0) yang hampir sama dengan biotipe non-B, begitu juga rataan masa generasinya. Namun demikian, laju pertambahan intrinsik (r) kutukebul B. tabaci biotipe B 2,5 kali lebih cepat dibandingkan biotipe non-B. Kutukebul B. tabaci biotipe B berlipat ganda populasinya (DT) 2 kali lebih cepat dibandingkan biotipe non-B. Kutukebul B. tabaci biotipe B berpotensi lebih berbahaya dibandingkan dengan biotipe non-B sehingga perlu diwaspadai keberadaannya.
