Sweet pepper line SBY28-1223

#The present invention relates to the field of plant breeding and, more specifically, to the development of pepper line SBY28-1223.

#The goal of vegetable breeding is to combine various desirable traits in a single variety/hybrid. Such desirable traits may include greater yield, resistance to insects or pests, tolerance to heat and drought, better agronomic quality, higher nutritional value, growth rate and fruit properties.

#Breeding techniques take advantage of a plant's method of pollination. There are two general methods of pollination: a plant self-pollinates if pollen from one flower is transferred to the same or another flower of the same plant or plant variety. A plant cross-pollinates if pollen comes to it from a flower of a different plant variety.

#The invention provides methods and compositions relating to plants, seeds and derivatives of pepper line SBY28-1223. This line shows uniformity and stability within the limits of environmental influence for the traits described hereinafter. Pepper line SBY28-1223 provides sufficient seed yield. By crossing with a distinct second plant, uniform F1 hybrid progeny can be obtained.

#Line SBY28-1223 exhibits a number of improved traits including resistance to Tobamovirus pathotypes P0, P1, P1-2, and P1-2-3, resistance to Tomato Spotted Wilt Virus pathotype P0, large fruits that are orange-yellow in color, and a short, compact plant. The development of the line can be summarized as follows.

#Year 1, Winter The F1 hybrid SVR 02895310 was made from the parents 992855 and 993128. The parent 992855 was a line with green to yellow maturing bell (LD=0.84) fruits and an open compact plant habit with resistance to Tobamo virus (L4 gene). The parent 993128 was a line with green to red maturing bell fruits (LD=0.90) with a compact plant with resistance to the Tomato spotted wilt virus. Neither parent was marketed directly as open pollinated lines. Year 2, Winter Plants of the F1 hybrid SVR 02895310 were transplanted into a hybrid trial as stake #00S-467 and allowed to self. SVR 02895310 was tested for Tobamo virus (L4 gene) and Tomato spotted wilt virus resistance and found to be resistant to both. Plant 00S-467-5 was selected and selfed. Plant 00S-467-5 was a compact plant with green fruits which slowly matured to pale red with a LD=0.93. The seeds of 00S-467-5 were designated 20002119. Year 2, Summer The F2 inbred line 20002119 was planted as stake #00F-2421. Line 20002119 produced compact plants with bell fruits segregating for yellow and red mature color. Line 20002119 was tested for resistance to Tobamo virus (L4 gene) and Tomato spotted wilt virus and found to segregate resistance to both. Individual plants were selected; the seeds of one plant, 00F-2421-8, were designated 20004002. Year 3, Winter The F3 inbred line 20004002 was planted as stake #01S-2082. Line 20004002 produced plants with green to dark-yellow maturing fruits. Line 200040002 was tested for resistance to Tobamo virus (L4 gene) and Tomato spotted wilt virus and found to be resistant to both. Individual plants were selected; 01S-2082-6 was designated 20013182. Year 3, Summer The F4 inbred line 20013182 was planted as stake #01F-1102. Line 20013182 produced plants with green to yellow maturing fruits, with a short (LD=0.73) bell shape. The average fruit set was 11 fruits per plant. Line 200013182 was tested for resistance to Tobamo virus (L4 gene) and Tomato spotted wilt virus and was found to be resistant to both viruses. Individual plants were selected; 01F-1102-7 was designated 20014091. Year 4, Winter The F5 inbred line 20014091 was planted as stake #02S-857. Line 20014091 produced plants with green to yellow maturing fruits, with a short (LD=0.80) bell shape. The average fruit set was 14 fruits per plant. Line 200014091 was tested for resistance to Tobamo virus (L4 gene) and Tomato spotted wilt virus and was found to be resistant to both viruses. Individual plants were selected; 02S-857-2 was designated 20021382. Year 4, Summer The F6 inbred line 20021382 was planted as stake #02F-318. Line 20021382 produced plants with green to dark yellow slowly maturing fruits, with a short (LD=0.74) bell shape. The average fruit set was 12 fruits per plant. Line 200021382 was tested for resistance to Tobamo virus (L4 gene) and Tomato spotted wilt virus and was found to be resistant to both viruses. Individual plants were selected; 02F-318-6 was designated 20022602. Year 5, Winter The F7 inbred line 20022602 was planted as stake #03S-705. Line 20022602 produced plants with green to dark yellow slowly maturing fruits, with a short (LD=0.71) bell shape. The average fruit set was 15 fruits per plant. #03S-705 was evaluated on uniformity, seeds of multiple plants were bulked and designated “SBY28-1223.” Year 5, Summer Planted SBY28-1223. This line produced a concentrated set of large, sweet, square-shaped yellow-orange mature fruit on a short, compact plant. Fruit were rather flat (LD=0.77), very smooth, with a medium shoulder and deep blossom end. The line is resistant to the Tobamo virus (L4 gene) and the Tomato spotted wilt virus.
