Hybrid registration HAP14F

The HAP14F hybrid is owned by the National Institute of Forestry, Agriculture and Livestock Research (INIFAP) and is registered in the National Catalog of Plant Varieties (CNVV) of the National Service of Seed Inspection and Certification (SNICS) with the definitive registration number CHI-031-100415, and Breeder’s Title No. 1443.

Origin and development of the hybrid

The wide poblano pepper hybrid “HAP14F” was developed in the San Luis-INIFAP Experimental Field by simple crossing of the lines ♀AP-3526 x ♂AP-30010 with genealogy AP-3526 () 8 and AP-30010 () 8, respectively; both parents are property of INIFAP. Obtaining the two parents as pure lines was by successive self-fertilization; for the formation and selection of the hybrid, the use of diallel crosses of seven progenitors (advanced lines) was used, using the Design 2 proposed by ^{Griffing (1956)}, until obtaining the hybrid of simple cross HAP14F (Figure 1).

Variety description

It was carried out through the use of qualitative and quantitative descriptors for pepper (^{IPGRI-AVRDC-CATIE, 1995}, ^{SAGARPA-SNICS, 2014}).

Botanical characteristics. HAP14F has a plant height of 68-78 cm and a foliage cover of 60-70 cm in diameter. The pubescence in leaves and stems is scarce. It has light green leaves with weak blistering on the surface, the margin of the leaf blade is entire unlike the witness variety AP-VR that presents it wavy. Presents flowers in intermediate position and the color of the anthers is purple with white filament. HAP14F is considered to be early cycle because the flowering and ripening of the fruit are presented at 39 and 118 ddt, respectively; while the AP-VR variety is intermediate cycle with 48 and 140 ddt (Table 1).

Horticultural characteristics. HAP14F produces fruits of intermediate green color in immature state (Figure 2) that turn a dark red color with a strong brilliance in mature state; while the AP-VR variety has a dark emerald green color that changes to bright red. The fruits of the hybrid are located in a slope position and have a length and diameter of 13.95 and 6.25 cm, respectively. The preponderant shape of the longitudinal section is triangular with a strong transversal undulation. A predominant feature of the fruits is the presence of a peduncular cavity with a medium depth. The texture of the surface is smooth and has two to three locules. The thickness of the pericarp is 4.13 mm, so it is considered thick (Table 2). This last character is important because the thicker it produces a better quality at the time of drying (^{Berrios et al., 2007}).

Performance evaluation under open sky conditions

During the 2013-2014 period, in different locations in the state of San Luis Potosi, the hybrid HAP14F and the control variety AP-VR were established under open sky conditions to evaluate fruit yield in green and dry or dehydrated. The management of the evaluation plots was according to the production systems of each locality. This hybrid had an average yield of 3.7 t ha^-1 of dry or dehydrated pepper and in green fruit it reached 23.1 t ha^-1 (Table 3), which was higher in comparison with the control variety in 15.6 and 12.7%, respectively. For the aforementioned, HAP14F is considered a good alternative for the Altiplano de México.

Conclusions

The hybrid HAP14F is a good alternative for the Altiplano of Mexico because it has better botanical, horticultural and production characteristics in relation to the control variety.
