Mongrel Natural Hybrid Series 2

Introduction
For an introduction to this topic, read the article Mongrel Natural Hybrid Series 1.

Mongrel Series Plant Scoring
The Harvest Size Index, In, which ranges from 0 to 100, compares the number of peppers a given plant produces, ni, to the maximum number of peppers produced by any member of the series, nmax, and is calculated such that the best plant will always score as In = 100. Thus:

Harvest Size Index equation

The Harvest Speed Index, Id, which also ranges from 0 to 100, compares the number of days to 50% harvest for a given plant, di, to the maximum and minimum number of days to 50% harvest for that series (dmax and dmin respectively). The Harvest Speed Index is calculated so that the fastest plant will always score Id = 100 and the slowest plant will always score Id = 0. Thus:

Harvest Speed Index equation

These two indices are then used to calculate an overall index IO, which provides a simple ranking of the plants based on both criteria. IO gives harvest size three times the weight as it does harvest speed, and is calculated such that 0 <= IO <= 100, thus:

Overall Index equation

Second Mongrel generation: Start
During the 2001 season, the 1D plant (seed code C4) scored the highest on the combined scale described above, so I used it as the mother. I removed the seeds from each of the four peppers saved from C4, keeping them separate, and labeling them 2A (first pepper) through 2D (last pepper).

In 2004, I started one cup (three seeds) from each of 2A - 2D, labeling these cups P1 through P4 respectively. This limited arrangement produces exactly four children, all of potentially different male parentage.

SMG: Notes
Germination rates and times were comparable for the four types (67-100% observed germination and 7-9 d to stand). Time to the development of the first true leaves was comparable for the 2A, 2B, and 2D cups (13-15 days); while the 2C cup produced two seedlings, they were both weak and sickly, and neither survived.

2B set fruit first (59 days), followed by 2A (62 days) then 2D (64 days). All three plants produced their first ripe pods over a similarly narrow range of dates: 2D at 94 days, 2A at 97 days, and 2B at 99 days. Days to 50% harvest were 128 (2A), 114 (2B) and 130 (2D), and harvest totals were 161, 34, and 123 pods respectively. As can be seen in the plot below, which shows % of total harvest vs. time, 2B's initial production was much faster than either 2A and 2D, both of which produced at a comparable rate percentage-wise for the initial portion of the harvest period. During the middle third of the harvest period, 2A maintained a higher production rate than the other two plants, and all three plants showed comparable decreases in productivity during the final third of the harvest period.

2A had a compact, bushlike habit; at 11" tall and 12" in diameter, it was much more compact than a typical Cayenne varietal. Leaves were dark green and correspondingly small, being 2" long and ovate-lanceolate in shape. The large (5/8" diameter) flowers had white petals and filaments, with light- and dark-green anthers. Fruit were very short, pendant, non-deciduous Cayenne-type pods, typically 3/4" to 1" long, with ends ranging from rounded to 3-lobed. Pods matured from light green to bright red.

2B had a very compact, sparse habit; it did not grow taller than 10" by the end of the season. Leaves were medium-sized (3" long) and ovate-lanceolate in shape. This plant had huge, droopy flowers that rarely opened more than halfway (flowers were 1 1/4"+ in diameter when fully opened). Petals were dirty white and anthers were dark blue-green. Pods were smooth, elongated tapered pods with slightly-rounded ends and were typically 2 1/2" long. They were thick-walled and brutally hot, and matured from light green to bright red.

2D was a larger plant, having a typically erect and bushy Cayenne habit (18" tall and 16" in diameter). Leaves were medium green and intermediate in size, being typically 2 1/2" long and ovate with a tapered point. Flowers were large (3/4" diameter) with white petals and light blue-green anthers. Pods were pendant, medium length (typically 2" long) Cayenne-type pods with blunt to round-pointed ends. They matured from light green to red.

SMG: Scoring

ID ni In di Id IO
2A 161 100 128 12.5 78.1
2B 34 21 114 100 40.7
2D 123 76 130 0 57.0


Based on these results, 2A (seed code P1) will be used for seed stock for the Third Mongrel Generation.
